    A swivel bracket can only be used with the 1,000 Pound Capstan Hoist. If you need to mount your 3,000 Pound Capstan Hoist, click here to check out our blog post on how to use the chain mount bracket.

     

    Assembling the Bracket


    The first part of mounting the capstan hoist requires assembling the bracket and attaching it to the truck.

    Step 1: Attaching the Swivel Plate to the Hitch

    Insert the swivel mount plate into a 2-inch hitch mount. The plate does not come with a key or pin to secure the plate onto the hitch. You will need to get a pin/key that fits the hitch you are using. **Do not use the setup until the plate is secured to the hitch with a pin/key.

    Step 2: Attaching the Swivel to the Plate

    The swivel bracket comes with four Grade 5 Bolts. Line the bracket up with the holes on the plate and secure the bracket into place with the included bolts. The bolts should be attached with the threads facing down. Ensure that you have tightened the bolts securely to hold the bracket in place.

    Step 3: Attaching the C-Bracket

    There is a pin on the back of the swivel mount bracket. This pin fits into the bottom of the C-Bracket to ensure that it is positioned correctly. Using a ½ inch Allen wrench secure the C-Bracket with the 4 provided screws.

    Step 4: Attaching the Capstan Hoist to the C-Bracket

    The C-Bracket has a pin on the back of it. This pin ensures that you will install the capstan hoist on the bracket correctly. The drum of the capstan hoist should be positioned directly above the center bolt of the swivel bracket. To correctly position the drum, make sure that the safety bar is on the backside of the load. Then, using the 6 screws that came with the C-Bracket, attach the capstan to the bracket.

  3. Shackles 101

    When it comes to lifting and rigging, knowing the hardware you are using is an important part of safety. A common piece of hardware used in lifting and rigging is a shackle. A shackle is a metal link, typically U-shaped, closed by a bolt or screw. Shackles are typically made from forged steel to provide very high tensile strength. Many US contractors have begun requiring domestically made shackles. This week our Gear Experts® are going to break down shackles.

    Domestic vs. Foreign


     

    It was mentioned above, but now it’s time to break it down further. Many US contractors have started requiring shackles that are made domestically. A domestic shackle is a shackle that has been made in the United States. They are often preferred to foreign made shackles due to better manufacturing and testing processes. Crosby, one of the most popular shackle manufacturers in the world, has a full selection of domestically manufactured shackles to meet your needs no matter what the job site requires.

    Screw Pin vs. Bolt Shackles


     

    Each job is unique and that means requirements are different. Not to mention, contractors may have preferences in addition to requiring domestic shackles. Apart from common things like U-shape size and capacity, the main difference between shackles will be whether they are a screw pin or a bolt shackle.

    Screw Pin

    A screw pin shackle is pretty self-explanatory. It is a type of shackle where the pin has a male threaded end, which tightens into the female threads in the body of the shackle. These shackles are popular because of their ease of use and are most commonly used on jobs that don’t require heavy duty attachment.

    Bolt

    A bolt shackle is pretty self-explanatory as well. It is a type of shackle where the pin has a male threaded end which is fed through the body of the shackle and secured with a bolt on the outside of the shackle. These shackles aren’t as easy to use as the screw pin shackles because of the requirements of securing the bolt to the pin. However, bolt type shackles are typically a better solution for jobs that require heavy duty attachment.

    Standards: ASME B30


     

    When it comes to lifting and rigging, which happens to include shackles – if you’re using them in a lifting and rigging capacity, the ASME B30 Standard is something that you need to be mindful of. The ASME B30 standard focuses on setting the standards for materials, rated loads, identification, inspection, repair, and removal. ASME B30 covers blocks and a range of other hardware used for lifting and rigging. We covered ASME B30 and provided a full breakdown of the standard in a previous blog post. You can find that post here.

  4. Mounting a Capstan Hoist to a Pole, Tower, or Beam with the Chain Bracket

    Capstan hoists revolutionized the art of lifting and rigging. What used to have to be done by hand or with complicated rigs that utilized truck power can now be done with a lightweight single unit piece. The capacity of the capstan depends on the model that you get and depending on the capacity, the way that you secure the hoist may be different. This week our Gear Experts® are going to break down how to mount a capstan to a pole, tower, or beam with the chain bracket.

    Chain Bracket vs. Swivel Mount vs. Straight Mount


     

    Before we go over how to mount a capstan with the chain bracket it’s important to outline the other options, when each is appropriate, and why you would use the chain bracket. The three main mounting options are a chain bracket, swivel mount, and straight mount. The straight mount and swivel mount bracket fit onto the hitch of a truck, while the chain bracket is attached to a pole, tower, or beam.

    The straight mount bracket can be used when you have easy straight access to your rigging location. The downside? It doesn’t have the ability to change direction without moving the vehicle it is attached to. If you think moving direction might be something you’ll need to do while on the job site, then the swivel bracket may be better suited for your rig setup.

    The chain bracket is similar to the straight mount bracket due to flexibility being limited. However, the chain bracket can handle more weight. In fact, the chain mount bracket is the ONLY bracket that can be used in combination with the 3,000 lb Capstan Hoist.

    Pole Mounting


     

    Mounting the hoist on a pole is a simple process that can be done in just a few minutes. Before beginning to mount the hoist the first step is to open the binder as far as possible by turning the handle counter-clockwise. The bolts in the chain tubes should be removed to allow the tubes to pivot.

    Next, place the chain over the top of the drum of the capstan and hold the hoist against the pole. It is recommended that you hold the capstan against the pole with your leg so that you have both hands free for the next steps. Next, Wrap the chain around the pole and hook them into the slots on the bracket. The final step is to turn the binders clockwise to tighten the connection of the hoist to the pole.

    ** Please note that after a heavy initial load you may need to re-tighten the binders.

    Tower/Beam Mounting

     


     

    The majority of steps for tower/beam mounting of the hoist are the same as pole mounting. However, there is one main difference. That difference is making sure that the two bolts located at the wheel tightener end of the chain binders have been secured in place through both the binders and the bracket. If secured correctly a 90° angle should be created between the chain binders and the bracket. This 90° angle allows the hoist to be mounted to square surfaces like those found on a tower/beam. After the angle has been created the remaining steps in the pole mounting section can be followed.

  5. Product Spotlight: The Sterling Pocket Hauler

    Certain situations call for a single person or team to lift an object or person that they normally wouldn’t be able to lift. That’s where mechanical advantage comes in. This week our Gear Experts® are going to talk about the Sterling Pocket Hauler and how it can provide a mechanical advantage for a range of applications.

    Mechanical Advantage


     

    First things first, let’s talk a bit about mechanical advantage. Mechanical advantage is “the advantage gained by the use of a mechanism in transmitting force; specifically: the ratio of the force that performs the useful work of a machine to the force that is applied to the machine”. Basically, mechanical advantage is the number of times the device multiplies the force you apply. Need to lift 60 pounds but only strong enough to lift 30? A device with a 2:1 (2 to 1) mechanical advantage will help you achieve that lift.

    The Pocket Hauler


     

    The Sterling Pocket Hauler is a small, lightweight, simple to operate system that provides a 4:1 or 5:1 mechanical advantage. This device makes lifting extremely easy for use in rescue, adjustable directional, tensioning, or a number of other rigging needs. The Sterling Pocket Haul System comes with everything you need to get the job done. It includes:

    → (1) 50’ 8 mm Rope with a Sewn Eye;

    → (2) Aluminum Mini-double Pulleys;

    → (2) Aluminum Auto lock Carabiners;

    → (1) 6 mm Prusik Cord; and

    → (1) Screwlink Carabiner

    **The pocket hauler does not come pre-rigged. But don’t worry – we’ve got you covered. You can check out our video on how to properly rig the Sterling Pocket Hauler Below.

    Save Energy


     

    To prove how much energy the Sterling Pocket Hauler’s mechanical advantage can save you, we did an experiment. In our experiment, we used a Rock Exotica Enforcer LC1 Load Cell to test the loads. We had a volunteer rig up to the haul system and used the Load Cell to show that he was 182 pounds. The next step was to change the configuration of the Load Cell to allow it to measure how much force was required to lift the volunteer using the haul system. In the 4:1 configuration it took 50 pounds of force to lift 182 pounds of weight. In the 5:1 configuration it only took 40 pounds of force to lift 182 pounds of weight.

    See the full experiment in the below video.

  6. Product Spotlight: The Rock Exotica MHP55

    The MHP55 from Rock Exotica has changed the game when it comes to lifting and rigging. This super-efficient, light, and versatile block is a must have for many rigging plans. This week our Gear Experts® are going to discuss why this block is such a great piece of equipment.

    ASME B30 Standard


     

    The Rock Exotica MHP55 meets the critical ASME B30 Standard for lifting and rigging. More specifically, Chapter 26-5 which covers rigging blocks, like those you would use with a capstan hoist on a tower. We covered the ASME B30 standard in a previous blog post. Click here to check out that blog post.

    Features


     

    This material handling 2.6 inch block features a red side plate to help differentiate it from other Omni-Block pulleys. The working load limit (WLL) is also a stout 4,500 pounds making it one of the strongest blocks in this category, even when compared to other steel blocks. A major advantage of this block is its ease of use. The side plates swing open, so you can install the rope while not detaching it from the system. Then, it locks back into place with a two-stage double-catch safety mechanism. The extremely efficient ball-bearing sheave reduces friction while lifting and rigging. It also has a swivel at the top to help the block align with the system. Last, but certainly not least, is rope compatibility. This block accepts ropes between 3/8 and ½ inch.

  7. Blocks for Lifting & Rigging: ASME B30

    Whether you are lifting or rigging, the block you choose is one of the most important decisions you will make. Your gear is the difference between a job well done and an accident with unforeseen consequences. Our dedicated Gear Experts® have spent years sourcing the best, and most reliable equipment to help you get the job done safely. This week we are focusing on blocks and the ASME B30 standard.

    We offer a wide range of blocks to fit all of your rigging and lifting needs. But, what exactly should you be looking for when choosing a block? Well, the most important things to look for are covered by the ASME B30 standard for lifting and rigging. More specifically, Chapter 26-5 which covers rigging blocks, like those you would use with a capstan hoist on a tower.

    Materials


     

    The rigging block should be able to permanently deform before losing the ability to support the load. This ensures that you should notice the block has been overloaded before it fails. We will cover inspection shortly, but remember that proper inspection is extremely important.

    The side plates should be made of metal, wood, or a synthetic material. Obviously, you’ll almost always see steel or aluminum blocks in the tower industry. The sheaves and load-bearing straps or fittings should be made of metal as well.

    Rated Loads


     

    Load weight should always be kept within the recommended limits of the manufacturer. It is also important to remember that this limit is the maximum load applied, not a single load line. What this means is that if the block is rigged at the top of the tower and you’re lifting something that weighs 1,000 pounds, there could be up to 2,000 pounds of total weight on the block. These concepts can get pretty complicated and are outside of the range of a blog post. For more information, check out a competent rigger training course.

    Proper Identification 


     

     

     

    ASME B30 26-5.5 covers proper identification. Each block has to have markings providing the manufacturer, rated load, and acceptable rope sizes. The block should also be maintained by the user to ensure these markings remain legible through the life of the hardware.

     

     

     

    Inspection, Repair, and Removal


     

    A qualified person should designate whether the hardware is suitable for rigging, and remove it from service if it’s not. Prior to use, all blocks should be inspected to verify compliance with ASME B30. A visual inspection should be performed each time the block is used. Permanently installed rigging hardware should have periodic inspections as well. Written records are not required for these inspections, but remember, if it doesn’t pass inspection you must remove it from service. Written records may not be required, but they are recommended. It makes it much easier to track inspection and keep everyone safe while on the job.

    If a block shows any of the following during inspection, they cannot be used in the field and should be replaced.

    • Missing or illegible identification
    • Misalignment or wobble in sheaves
    • Excessive sheave groove corrugation or wear
    • Loose or missing nuts, bolts, cotter pins, snap rings, or other fasteners or retaining devices.
    • Indications of heat damage or arc strikes
    • Excessive pitting or corrosion
    • Bent, cracked, twisted, distorted, or broken load-bearing components
    • Excessive wear, nicks, or gouges
    • 10% reduction of the original dimensions at any point on the device
    • Excessive damage to load-bearing threads
    • Evidence of unauthorized welding or modifications
    • For hooks and shackles, removal criteria specified in those B30 standards
    • Any other condition including visible damage that causes any doubt as to the integrity of the block.

    Repairs of modifications must be specified by the by the manufacturer or a qualified person. The replacement parts should meet or exceed the original manufacturer specs. Unless advised by the manufacturer, modifications are not recommended.

    Operating Practices


     

    Obviously, load ratings should not be exceeded. Make sure you’re keeping clear of the block, its running lines, load, or any other part of the system during lifting. This includes walking or standing under a suspended load or lifting line. Also, don’t stand next to a rig when the line is under tension.

    As for rigging practices, avoid sharp angles or edges that could damage the block. And be sure not to drag blocks along abrasive surfaces. The load applied to the block should be in-line with the sheave to prevent side loading. Blocks with swivels help to avoid these problems.  Also, make sure your rope is securely in the groove of the sheave. Shock loading should also be avoided.

    This is not a comprehensive training. Before doing any lifting and rigging a competent rigger course should be completed. We also have a full line of training courses that are available for a range of different subjects. Those can be found here.
