Features of manual winch equipped with built-in stopper (SI type) series

Please select this winch for an automatic braking system. A braking stopper arm located on outside of the winch can release accidentally in busy locations (schools, public facilities, a place where an unspecified number of people come and go, etc.). With the SI type winch, the braking stopper mechanism is embedded in the special sealed clutch cover for safety. You can wind-up and down the load without risk of accidents.
This type can be separately produced as models made of stainless-steel or steel. For example, when ordering a product please specify GM-5-SI or ESB-5-SI.

Model: GM-1-SI / GM-3-SI / GM-5-SI / GM-10-SI / GM-20-SI / GM-30-SI

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.

Safety design when it is not necessary to release brake

This winch is suitable for busy locations with many people around (lifting of various nets used for physical education at schools, lifting of basketball goal boards, lifting of stage equipment, etc.). The stopper arm with a brake release button is eliminated, and the stopper mechanism is embedded in the sealed clutch cover. This winch ensures safety and prevents the need to remove the stopper during wind-up / wind-down of the load.
