European Standard Runway Long Traveling Electric Hoist Single Girder Gantry CraI. Brief Introduction of Long Traveling Single Girder Gantry Crane
European-style single-beam gantry cranes are rail-operated small and medium-sized lifting equipment, mainly constitute by main beam, legs, bottom beam, hoisting mechanism, operating mechanism and electrical control part. The machine uses high-strength materials, improve the carrying capacity. Limit distance from hook to both sides is short but has large working arrange. With lower height above the rail, it makes full use of space of factory building.
II. Advantages of Single Girder Gantry Crane
1. Main beam
The main beam uses square structure, compared with the traditional I-beam welded beam, higher strength, electric hoist on it run more stable.
It employs motor of hoisting mechanism and reducer imported from Germany. The integrated and compact design of hoisting motor, reducer, reel and limit switch saves space for the user. Modular design increase the reliability of mechanism meanwhile reduces the time and cost for maintaining.
It has more and faster hoist speed and various pulley ratio which can be selected. The standard travelling mechanism of trolley is controlled by converter, with speed of 20m/min, which makes a little swing and accurate position if hoisting items while trolley travelling as well as lifts precision and valuable items reliably.
