Feature of Steel Rotating Manual Winches: Model GM
This is the base grade of a MAXPULL manual winch. This winch is equipped with a built-in mechanical brake. Rotating the handle clockwise winds up the wire, rotating it counterclockwise winds down the wire, and the brakes automatically works at the stopped position of the load. The brake can be released (when there is no load).
Model: GM-1 / GM-3 / GM-5 / GM-10 / GM-20 / GM-30
Simple operation
As the machine efficiency is high, the hand load during operation is very light compared to that of competitors’ winches and you can carry out the work easily. This winch has a compact design with minimal weight and very convenient to carry or move. In addition, the main unit can be easily attached using predefined bolts. Another major feature is that each part is made by press processing, and the whole winch is assembled with bolts, so it can be easily disassembled. If a repair is necessary, anyone can easily repair and assemble the winch by following the instruction manual and purchasing the parts.
Exceptional durability
Ball bearings from leading manufacturers are used for all of our winch products. These ball bearings make the winding process light and exhibit outstanding strength against wear. For the reducer, our company’s custom designed heat treated gear uses an unique transposition method to allow the user to work with ease. The mechanical brake also has a mechanism that freely adjusts the gap so it is extremely durable. All surfaces are painted and treated which makes the winch resistant to rust with unrivaled durability in any working environment.
Reliable safety
This winch is extremely safe because of carefully selected material parts, advanced design and technology. Especially for the parts where load is applied in a concentrated manner, the strength is further increased by combining ribs or double plates made by precision press processing. The mechanical brake has a double safety mechanism, so even if there is an impact applied to the claw arm, the brake will remain in place. The wire rope is fixed to a specially designed drum using a double safety structure. The end of the wire rope can be easily fixed to the drum using a Hex key L-wrench included with the product. This MAXPULL original design ensures a highly reliable and safe product.
Standard (brake can be released) type
This is a product type that can release the brake by disengaging the stopper when there is no load. As the drum can be idle, the wire rope can be easily pulled out by just pulling the wire rope wound around the drum after removing the handle. This function is convenient when the wire rope is usually stored in the drum and it is pulled out only during the work.
* Do not release the brake under any tension such as during vertical suspension. Otherwise, the brake does not function and a serious accident may occur.
