Japan, MAXPULL
Maxpull Dust-proof and drip-proof manual winch (SIC type)
Made in Japan
Manufacturer: Maxpull
Model: GM-1-SIC type/GM-3-SIC type/GM-5-SIC type/GM-10-SIC type/GM-20-SIC type/GM-30-SIC type
Features
As with the SI type, the stopper arm that releases the brake to allow the drum to idle has been eliminated, and the entire stopper mechanism is built into a special sealed clutch cover. Please select it in a place with bad atmosphere such as dust.
It is possible to manufacture for all stainless steel and all steel models. When ordering, please specify, for example, GM-5-SIC, ESB-5-SIC.
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 great feature is that each part is made by press processing, and the whole is assembled with bolts, so it can be easily disassembled. Even in the case of repair, anyone can easily repair and assemble 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.
Designed with dust and drip resistance in mind for brakes
Like the SI, this type does not have a stopper arm that releases the brake to idle the drum, and the entire stopper mechanism is built into the closed clutch cover.
In order to make the entire brake mechanism dustproof and drip-proof, a “shield packing” is used on the mounting flange surface of the clutch cover, and a “shield ring” is used on the sliding part with the clutch to improve airtightness. . The maintenance period of the brake part tends to be relatively long compared to other models because the contamination of foreign matter from the outside is reduced. In addition, the airtightness creates a soundproofing effect, and the noise emitted from the brake mechanism is kept small.

An example of a site where the SIC type is used
Even if exposed to rain, water droplets are less likely to enter the brake mechanism.
