- Scope
- This standard specifies the type, basic parameters, dimensions, technical requirements, inspection rules and markings, packaging, storage and coupling installation of spherical roller couplings for reels (hereinafter referred to as couplings). This standard is applicable to the connection between the reducer and the drum of the crane hoisting mechanism and the couplings connected by other similar mechanisms, which are used to transmit torque and bear radial load. The operating temperature is -25℃～+80℃; the nominal transmission torque is 5kN·m～900kN·m, and the allowable radial force is 165kN～520kN.
