The main products of chain hoists Explosion-proof chain hoists, chain hoists 1: aluminum bronze, beryllium HSZ as a rough one ton chain hoists, chain hoists, chain hoists explosion H62 copper alloy shell with proof hoists applicable In explosive environments HSZ chain hoist prices, such as chemical, offshore and other operations. 2. Explosion-proof chain hoists rotating gear after high-temperature heat treatment to achieve the gear, according to a high wear resistance. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, small size, durable. 3. proof hoists work principle: Hands chain drag chains, bracelets wheels began to turn HSZ chain hoist, friction ratchet brake seat (to be pressed into one) co-rotating HSZ chain hoist manufacturers, five tooth long axis will rotate sprocket, tetradentate minor axis and the spline hole gear. Thus, the lifting device on the spline sprocket holes on the drive gear lifting chain, lifting heavy objects smoothly. Standard chain hoists each product must be accompanied by a product maintenance manual, production licenses and product certification mark. Two products should be clear and durable signage. 3 Do overload or oblique lifting crane. Ban hanging pull buried or heavy condensation on the ground. 4 hanging chain hoists bearing point must be strong and stable. 5 hanging, tied with a rope and chain safety factor of not less than six non-rebate to the next hook lifting heavy lifting chain hoists 7 allowed to throw. 8 users can not change the original design of the product. 9 Replacement parts must meet the original design requirements.
