  1. Not Your Average Metal Loop

    This little loop of metal has come a long way. The term carabiner comes from German, “karabinerhaken” which means hook for a carbine. Before they were saving your life, the first carabiners were used for sailing and weren’t made to support a load. They usually just had a spring loaded wire closure, which was not made to catch a person’s weight, when they… say… fell off a tower.

     

    Two Carabiners

     

    The first load-bearing carabiners were hand forged steel. Lighter aluminum versions came around WWII but there were no safety features, such as auto-twist gates. And the shapes were pretty basic ­– usually just an oval, which led to cross-gate loading, causing the ropes to slip out. That’s bad.

     

    Obviously, a lot has changed over decades. Carabiners are better, and you should be pretty pumped about that. Instead of an oval there are offset D shapes or larger pear shaped carabiners. The closing function is much better. Instead of a light wire gate, there are screw or auto twist gates. Each revision has made the carabiner more functional and safer. That’s good.

    Carabiner ANSI Gate

     

    In our industry, carabiners must comply with specific regulations. The American National Standards Institute (ANSI) says that for a carabiner to be used in fall protection it must have a strength rating of 5,000 pounds, or 22 kilonewtons and gate strength of 3,600 pounds, or 16 kilonewtons. The tested and approved ratings are always stamped or printed somewhere on the carabiner and gate. If you're not sure if yours are rated, or the stamps aren't visible… DON’T USE THEM!! (In case you were wondering: A newton is the force required to accelerate a one-kilogram mass one meter per second per second. 1000 N = 1kN = 224.8 lb force) OK! Enough math.

     

    There are obviously a wide variety of carabiners, and they all have the same basic parts:

    • The body, which is a loop
    • The gate and hinge, which open to allow attachment
    • The inner sleeve, which is what the gate twists around

     

    Different carabiner options may work better for one application over another.  GME Supply can help you select the best one for you, so you can Climb Higher!

  2. Hand Injuries

    Hand ProtectionYou use your hands to operate basically any tool. You use your hands to climb, carry, tighten, loosen, hold, and lift. If you injure your hands, you’re not going to be productive. Your hands are probably the most important part of your body. Turns out, they’re also the most injured.

    According to the CDC, there are almost 1.9 million hand injuries per year by workers in the US. 1.9 million!

    Hands can be injured in a variety of ways:

    • Cuts and punctures
    • Extreme temperatures
    • Chemical and thermal burns
    • Vibrations
    • Impact

     

    Obviously all injuries can’t be prevented but according to one study, wearing gloves reduces the risk of injury by 60%. Meanwhile, 70% of hand injuries are from workers not wearing gloves. Another large percentage was wearing incorrect or damaged gloves.

    Hand injuries also cost a lot. $382 million a year. They’re the second most expensive injury, only being beat by back strain.  They will crank up your insurance, could lead to fines or even law suits. An average claim on a hand injury is over 6 grand. And while that injury is being taken care of, you’re losing productivity.

    There is a very wide variety of glove types. Whether you need gloves that add grip and dexterity or increase cut and abrasion resistance, GME Supply can find you the right glove to meet your needs. We carry gloves for any application from a variety of brands.

    M18™ is the fastest growing 18V system around. These things do what you used to need an extension cord and a corded tool to do. If you haven’t heard about it, here’s the short version. They’re professional grade, lightweight, ergonomic tools with 18V lithium batteries that keep going long after others have died. You don’t make money while you’re waiting for your batteries to charge!

     

    Milwaukee Fuel Drills

     

    The M18 Fuel™ System has killer brushless motors and REDLINK PLUS™ that makes sure your tool is working as hard as it can and as efficiently as possible. While we’re on the subject, let’s look at the differences between brushed and brushless motors.

    Now, motors are all about magnets. As we all know, opposites attract and likes repel. When put together and correctly controlled, magnets inside a motor create rotational motion and spin the axle. Motors are everywhere, including power tools like drills.

    There are two basic types of motors that are used in drills: brushed and brushless. Both do essentially the same thing. They pump electricity through an electromagnet which is positioned near permanent magnets. This creates spin. The polarity of the magnet has to be flipped every 180 degrees, though. If the polarity weren’t changed, the motor would turn 180 degrees and stop. The way this polarity flip is created is the difference between brushed and brushless motors.

    In a brushed motor, the electromagnet passes through a pair of brushes which flip the polarity and makes the motor spin. While this is a very simple and cost efficient way to make a motor, it does have drawbacks. The brushes can spark and create electrical noise, and they also limit the maximum speed of the motor. The motor also runs hotter due to the friction from the brushes. The biggest drawback, though, is the fact that the brushes wear out. If the motor isn’t serviced, eventually it will start losing power and then fail. That's an expensive repair.

    A brushless motor basically turns a traditional motor inside out, eliminating the need for brushes. It puts the electromagnets on the outside and the permanent magnet as the rotating piece on the inside. The polarity swap is handled by a small computer which rapidly turns the electromagnets on and off to spin the rotor. While this motor is more expensive to manufacture, it is more efficient and has a longer life. These very precise motors have virtually no wear parts and operate much cooler.

    Each motor has it's place, but the latest and greatest is definitely the brushless motors that are featured in the M18 Fuel™ system.
