SR wheel block system –
inconspicuous all-rounders for cranes and systems


Wheel blocks are unobtrusive all-rounders in STAHL CraneSystems’ range of products. However the potential applications for these reliable heavyweights are practically unlimited: storage and retrieval machine, gantry crane or stadium roof – our wheel blocks can get practically anything heavy moving. The rigorously modular system is designed for wheel loads from 5 t to 30 t. You can choose from six wheel diameters: 125, 160, 200, 250, 315 and 400 mm.
The compact units consist of a metal housing with integrated wheel. Available in various designs, they are bolted or welded to customers' machine or system components.

Option: guide rollers
The standard guide rollers are designed for flanged wheels. In special cases, guide rollers can be mounted on the wheel block. This version is used for example with overwide rails or to reduce rolling resistance. The use of additional guide rollers is also important to reduce skew forces and thus minimise wear on the runway rail.
