  1. 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.

  2. Safety & Jobsite Banners

    Keeping employees, team members, and other people on the job site safe is at the top of mind for many people. One integral part of keeping people safe on the job site is ensuring that they are aware of the hazards they may encounter. OSHA requires signs to be posted on job sites which is a great first step. In this week's blog post our Gear Experts® are going to talk about our job site safety banners and motivational workplace banners.

    Job Site Safety Banners


     

    Our job site safety banners make it easy to quickly get your job site OSHA compliant. All of our banners come with grommets on each corner and in the middle so that you can easily hang them. These banners are available in two sizes – 4 x 2 or 6 x 3 foot. These banners feature all of the common job site signs – dangers, warnings, cautions, and notices, that are all required by OSHA.

    Customizations


     

    We’ve got two main types of job site safety banners – Tower Climbing Job Sites and Construction Job Sites.

    Tower Climbing Job Sites:

    The tower climbing job site banners have notices that are directed towards… you guessed it, tower climbing job sites. The notices are for fall protection, RF monitors, and overhead work.

    Construction Job Sites:

    The construction job site banner is directed towards general construction. It features notices for electrical hazards, speed limits, and PPE.

    Custom Banners:

    We know that not all job sites are created equal. That’s why we can work with you to customize your job site banner. We can customize the signs that are on the banner, provide a banner with clear pockets so that you can switch out signs when needed, and even add your logo to the banner so that people know which company is on the job site. For more information about customization please contact one of our Gear Experts® or click here.

    Tough Enough to Actually Use


     

    The job site is not a place for the faint of heart and the equipment should be just as tough as the men and women who are there to get the job done. At GME Supply we strive to make sure that the products we sell are a reflection of you – our tenacious customer. All of our job site banners are made of extra-heavy-duty ultraflex 15 oz PVC material. What does that mean? It means that you don’t have to worry about fading, cracks, tears, or rips.

    Motivational Workplace Banners


     

    Banners that are required by law are great. But, banners that motivate employees to stay safe and instill a sense of pride are great too. That’s why our Gear Experts® have put together a selection of motivational workplace banners. These banners are 4 x 2 feet and come with a variety of messages. They are made of the exact same ultraflex 15 oz PVC material that the job site banners are made of. These banners can also be completely customized.

  3. Manufacturer’s Spotlight: Petzl

    We know that as a tower climber your gear is important – because it can be the difference between making it home every night, and not. But, where does that gear come from and how did the company that made your gear get started? This week our Gear Experts® have teamed up with Petzl to bring you a special look into one of the companies that pour their soul into your safety.

    The Beginning


     

    Petzl’s story begins above the French town of Grenoble in the early 1930s. Two brothers, caked in mud and in their early twenties, emerge from a cave. For the elder brother, Edmond, this caving experience was one in a series of adventures that would lead him to Canada. For the younger brother, Fernand, this experience would change his life and the lives of many others.

    Fernand Petzl was an inquisitive tinkerer. From an early age, he learned how to work with machines and by the age of twenty-five he had his own business doing industrial modeling for a nearby factory. It was around this time that Edmond took him caving.

    Innovation


     

    Fernand spent his time exploring the limestone mountains above Grenoble that are bored with caves. This was before the invention of nylon ropes, so Fernand and his friends carried hemp cords and wooden ladders into the caves. Soon, all of Fernand’s free time was spent either underground or in his machine shop devising better equipment for his subterranean explorations.

    Strong nylon rope changed the nature of caving. A rope could be coiled into a tight bundle and carried through the cave, then unfurled to span distances or aid long climbs. With this new tool came new devices and techniques for climbing and descending rope within caves, and here is where Fernand Petzl, his knack for tinkering, and his small shop became famous in the caving community. The name PETZL which explorers had once found marking new passages underground, now became stamped into the actual equipment cavers carried.

    Cavers from all over France would gather in the workshop and discuss the new techniques, technology, and exploration. Through this exchange of ideas, Fernand would modify or invent new devices for ascending and descending rope. Others began to take notice of the equipment used for cave exploration. Mountaineers began purchasing rope ascenders and descenders as they raced to summit the world’s highest peaks. By the 1970s Fernand had hired his first employee and his son, Paul, was working in the family shop.

    From Recreation to Profession


     

    In spite of Fernand's progress, it wasn’t until the 1980s that Petzl first moved in a direction that would change its very DNA. Ever since Fernand’s work in caves other explorers had taken notice of the equipment made by the father-son team. But it was the Électricité de France (EDF, France's national utility company) that helped change the business.

    At the time lineman worked with bulky, uncomfortable, outdated safety equipment and accidents were not uncommon. The EDF first looked to mountaineering gear, but soon the Petzls developed a harness specifically designed for the needs of a professional. Like the cavers many years before, industrial workers had discovered the many advantages afforded by fixed ropes. By now the Petzls' company employed over thirty people.

    Revolutionary Gear 


     

    Two of the innovations created in Crolles, France, have fundamentally changed the face of the rope access community: First, the I’D (for Industrial Descender) is available in small and large sizes. The I’D grew from the STOP descender used in caves, then the technology was evolved for climbers as the GRIGRI, and finally expanded upon into the I’D. This device became the go-to descender for anyone frequently descending fixed lines.

    The second device that changed Petzl’s line was the ASAP (the name comes from its purpose to stop As Soon As Possible). Used as a backup for rope access and as a fall arrest device, the ASAP uses centrifugal force to sense when a user is falling on the rope and arrests their fall. While its ability to track with the user as they move up and down was welcomed, the major development in the ASAP was how it took into account the user's psychology. Previous devices could be disengaged by squeezing or grabbing them. Unfortunately, this is also a worker’s natural reflex. With the cam wheel enclosed in the ASAP, grabbing around the device would not interfere with its locking ability.

    Modern Day


     

    Today the needs of industrial workers are more than half of the Petzl focus, with specific tools and devices for arborists, rope access techs, tower climbers, riggers, first responders, tactical needs, and other workers operating at height. Though Fernand passed away in 2003, Petzl remains a family owned and operated, business. Fernand’s son Paul runs the company, and Paul’s sons Olivier and Sebastian both work for the firm, continuing the innovation and tinkering tradition of their grandfather, but now well beyond the quiet caves of the French Alps.

  4. SRL ANSI Classes

    An SRL, or Self-Retracting Lifeline is a device that contains a spring-loaded retracting web or cable lanyard wound around an internal drum. This device automatically locks and arrests the fall of a worker. SRLs come in a range of different shapes and sizes. There are also a range of types available for different environments and mounting styles. However, there is one thing that all SRLs used on a job site have in common: ANSI Class ratings. This week our Gear Experts® have put together a guide outlining the ANSI SRL Classes.

    ANSI Classes


     

    ANSI Z359.14-2014 classifies SRLs into two classes. Those classes are Class A and Class B. The main differentiators between the two classes are stopping distance and arresting forces.

    Class A:


     

    In order for an SRL to be Class A it must meet the following requirements:

    → Have a maximum arresting distance that does not exceed 24 inches.
    → Have an arresting force that does not exceed 1,350 pounds (6 kN)
    → Have a maximum peak force of 1,800 pounds (8 kN)
    → After environmental conditioning (hot, cold, or wet) the average arresting force must not exceed 1,575 pounds (7 kN)
    → After environmental conditioning (hot, cold, or wet) the maximum peak force must not exceed 1,800 pounds (8 kN)

    Class B:


     

    In order for an SRL to be Class B it must meet the following requirements:

    → Have a maximum arresting distance that does not exceed 54 inches.
    → Have an arresting force that does not exceed 900 pounds (4 kN)
    → Have a maximum peak force of 1,800 pounds (8 kN)
    → After environmental conditioning (hot, cold, or wet) the average arresting force must not exceed 1,125 pounds (5 kN)
    → After environmental conditioning (hot, cold, or wet) the maximum peak force must not exceed 1,800 pounds (8 kN)

    Comparison:


     

    Each of these devices has benefits based on the jobsite and working conditions. As you can see above a Class A device will stop your fall faster, but with more forces applied to the body. Class B devices, on the other hand, will take longer to arrest the fall, but will reduce the g-forces significantly. Which device you should use depends on your environment. If you have plenty of fall clearance below you, then a Class B device could be the perfect fit. However, if you are working in close quarters and don’t have that extra fall clearance, then you will need a Class A device.
