Ratchet type handle manual winch MR-SI series feature
Winding up and down is enabled by right and left reciprocating movements of the ratchet type handle. This winch can be directly installed on walls or floors with narrow spaces where it is impossible to rotate the handle 360 degrees. In addition, this winch can be also used as a rotary winch the same way as the GM series.
Model: MR-1-SI / MR-3-SI / MR-5-SI / MR-10-SI / MR-20-SI / MR-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.
