	Portal Slewing Crane
	MQ Model portal crane is a multi-function large size loading and unloading equipment for handling of chandlery. It is applicable to all kinds of big docks and ports and can move freely along the pre-set rails. This model is widely used in various fields with high operating efficiency. This Model includes single girder type and single Rack Luffing type. Facilitated with compensating pulley system, the crane is capable of horizontal movement with load and joint operation for slewing, hoisting and luffing at any angles with load. The crane has the advantage of energy saving and high efficiency. The activities conducted by this machine are stable , reliable, and safe.     This model of crane is designed and manufactured according to GB3811-83 Criterion of Designing for Cranes, , GB6067-85 Safety Rules on Cranes, GB17495-1998 Technical Requirement on Portal Crane, JT400-1999 Safety rules on Portal Crane and other related standards.
