Hook block keeps you moving
25 April 2008
The McKissick Quick-Kit is a compact, mobile system designed to provide a customised replacement hook block within minutes of a crane going down. The system can be configured to replace more than 80% of overhead crane block applications, according to distributor Crosby. It covers wire rope diameters from 6.5 to 26 mm and has adjustable sheave spacing to match different requirements.
Included with the kit in its portable case are assembly instructions and tools to make the replacement. Also included is software that allows, for example, printing a dimensional drawing of the exact crane block required and specific assembly instructions.
Kits are available in ten sizes: The 751, a single sheave series in four different sizes with working load limits of 2, 3, 5, 7.5 and 10 tonnes; the 752, a double sheave type with working load limits of 3,5, 7.5, 10 and 15 tonnes.
Sheave bearings are all maintenance free and sealed for life (10,000 hours), the removable housing allows the block to be reeved without complete disassembly, and an anti two-block device can be attached.
