Explosion-proof chain hoists chain hoists works are driven by human pulling the hand chain bracelet wheel rotation, chain hoists prices will ratchet friction plate, brake pressure into one common rotating seat, tooth long axis will rotate pieces gear, short gear shaft and spline hole. This wholesale chain hoists, lifting apparatus sprocket holes in the gear spline on drive lifting chain, thereby smoothly heavy lifting. Products using one-way ratchet friction plate system is under load hoist brake on their own, Jiangxi chain hoists, under the action of the spring pawl and ratchet engages the brake to ensure safety. Selection Method Selection proof chain hoists have two points: one is to select the type of protection, and the other is to select mechanical properties. Manufacturing material proof performance depends on whether the use of explosion-proof tools have been tested and the National Light Industry Quality Supervision and Inspection Center, the only material proof certificate in order to ensure the overall performance of explosion-proof chain hoists; the other is to look at the mechanical properties, depending on whether the product is After testing the national handling equipment Quality Supervision and Inspection Center, and only after testing the product quality can only be guaranteed. The maintenance of a chain hoist brake, the spring pressure should be less than the putter thrust; 2, when the brake is open, chain hoists spot, on both sides of the gap between the brake shoe and the brake wheel should be equal; 3, the brake drum center brake shoe center error should not exceed 3mm; when the brake is released, tilt and non-parallelism brake shoe and brake wheel brake wheel width should not exceed 1/1000; 4, after the brake open, the parts not should jamming. 5, does not affect the chain hoist brake clearance, the compensation stroke better.
