SELECTION & ORDER BASIS
Specify the application before the model.
A pulley block must be matched to the rope, sheave geometry, reeving arrangement, connection and loading direction. Specify the entire operating configuration rather than only the nominal capacity.
Specify sheave diameter, rope diameter, number of sheaves, hook or eye fitting, load requirement and operating environment.
ZECH supports industrial distributors and project buyers with model matching, catalog specifications, packaging confirmation and order-specific documentation. Final technical details are confirmed with the quotation.
