Maxpull Ratchet type manual winch MR series

Made in Japan
Manufacturer: Maxpull
Model: MR-1 type / MR-3 type / MR-5 type / MR-10 type / MR-20 type / MR-30 type

Features

Because of the ratchet type handle, it can be rolled up and lowered by left and right reciprocating motion. Even in narrow spaces where it is impossible to rotate the handle, it is possible to work by attaching it directly to the wall or floor. It can also be used as a rotary winch like the GM series.

Easy operability

Due to its high mechanical efficiency, the manual load during operation is very light compared to winches manufactured by other companies, making work easier. Due to its compact design, it is lightweight and very convenient to carry. In addition, the body can be easily fixed with the prescribed bolts. Another big feature is that each part is made by press processing, and the whole is assembled with bolts, so it can be easily disassembled. In the case of repair, anyone can easily perform repair and assembly by simply purchasing the parts and following the instruction manual.

Outstanding durability

All bearings use ball bearings from leading manufacturers. It is light to wind up and exhibits outstanding strength against wear. In addition, the speed reducer employs our unique shifting method gear that has been subjected to special heat treatment, allowing work to be performed with ease. The mechanical brake also has a mechanism that allows you to freely adjust the gap, so it has excellent durability. In addition, the surface is completely prepped and baked on, so it is resistant to rust and can be used in any work location.

Safety you can trust

Carefully selected materials and advanced design and technology boast an extremely high level of safety. In particular, the parts where the load is applied intensively are combined with precision press-processed ribs or double plates to further increase strength. A double safety mechanism is adopted for the mechanical brake, so even if an impact is applied to the claw arm, no braking will occur. In addition, the wire rope is fixed to the drum with a double safety structure using a special drum that ensures waste winding. Wire rope ends can be fixed to the drum easily and securely with the included hexagonal L-shaped wrench. All are highly reliable and safe designs unique to our company.
