Features of dust proof / drip-proof manual winch (Type-SIC) series
In the same way as SI type,the stopper arm with a brake release button is eliminated from this winch. The entire stopper mechanism is embedded in the sealed type special clutch cover. In addition, sealed packing and sealed rings are added to ensure dust resistance and drip-proofness. Please select this winch for hard environments due to dust.
This type can be separately produced as models made of stainless-steel or made of steel. When ordering a product, please specify GM-5-SIC or ESB-5-SIC.
Model: GM-1-SIC / GM-3-SIC / GM-5-SIC / GM-10-SIC / GM-20-SIC / GM-30-SIC
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.
Design considering dust resistance / drip-proofness of brake part
This winch has no stopper arm that idles the drum by releasing the brake the same way as a SI model. The stopper mechanism is embedded in the sealed clutch cover.
In order to make the brake mechanism dust proof and drip proof, “sealed packing” and “sealed ring” are used for the flange surface for attaching and sliding part with the clutch to improve the sealability. The brake maintenance period is comparatively longer than other models because dust from outside can be reduced. In addition, the sealability produces a soundproofing effect and noise generated from the brake mechanism can be reduced.
Examples of SIC type usage site
Even if the product is exposed to rain, water droplets do not easily enter the brake.
