Maintenance of a chain hoist brake, spring pressure should be less than putter thrust; 2, when the brake is opened on both sides of the gap between the brake shoes and brake wheel should be equal; 3, wheel hub and brake shoe center error should not exceed 3mm; when the brake is released HSZ 1 ton chain hoist, tilt and non-parallelism shoe and brake wheel brake wheel width should not exceed 1/1000; 4, the brake open, the parts There should be no jamming. 5, does not affect the chain hoist brake clearance situation SHZ chain hoists price, the bigger the better compensation for travel. Qingyuan Crane Co. (Address: Hebei Qingyuan East Lu Economic Development), 1992 construction, the registered capital of 8 million, 100 employees, is an electric hoist manufacturers. Hoists commonly used models are: HSZ, HS-C, HS-VT, explosion-proof chain hoists and so on. Hoists as an upgraded version of the fixed pulley, chain hoist components fully inherited the advantages of fixed pulley, while using a combination of reverse backstop brakes reducer and chain pulley block, the symmetrical arrangement of two spur gears rotating structure, simple, durable and efficient. Hoists hands by pulling the chain, bracelet wheel rotation HSZ chain hoist, the friction plate ratchet brake pressure into one common rotating seat, then the long axis of rotation of the tooth sprocket, gear and spline hole short axis gear. Such HSZ chain hoist manufacturer of lifting equipment on the spline sprocket holes on the drive gear lifting chain, lifting weights so smoothly. Using one-way ratchet friction plate brake, brake under load on their own, with the ratchet pawl is engaged in the action of the spring brake safety. HSZ chain hoist manufacturer | Sichuan HSZ chain hoist | Qingyuan Xinyu Xinyu lifting by Crane Co. provided. Qingyuan Xinyu Crane Co. (xyqz0312.1688.com) strong, credible, Baoding in Hebei engineering, construction crane industry has accumulated a large number of loyal customers.
