Product Description

QTZ50 (TC5008) tower crane

Features:
QTZ50 tower crane is based on microcomputer design platform of tower crane, applying group technology, combined design technology and FE analysis technology, combining with advanced international technology and requirements of domestic construction market, develop and design more advanced tower crane in China.
The tower crane is horizontal arm support, trolleying, top slewing and hydraulic jacking tower crane. Its jib length is 50m, max. Load moment is 540 KN. M, free standing height is 30m, max. Attached height is 120m (2 falls).
Self-weight of the crane(without balanced weight and anchors) is 22.56t, total capacity of whole crane is 25.1 Kw. Advanced parameters, stable performance, good looking, excellent quality, simple structure, equipped with advanced safety devices, simple maintenance and competitive price make TC5008 tower crane be popular in small and medium construction enterprises.
