CATALOGUE OVERVIEW

About this component series

Qidong Datong’s construction-hoist gearbox catalogue separates TCW worm drives, TSK two-stage spiral-bevel drives and JNSK three-stage spiral-bevel drives. TCWS identifies the worm-above layout and TCWB a brake-equipped version; TSKZ is the direct-connected version and TSKB includes a brake. These suffixes identify different assemblies. Match the hoist transmission layout and brake arrangement before requesting reduction ratio and permissible output torque.
