MODEL GCL(GCT) HAND-PULLED SINGLE RAIL TROLLEY Application: Model GS series of hand-pulled single rail trolley is driven by pulling the hand chain and travels along the lower edge of "I" shaped steel beam. Working in set with chain blocks, it forms a bridge crane, a single beam crane and a cantilever crane. It is widely used in factories, mines, wharfs, warehouses and construction sites for the installation of machinery and equipment, and for lifting and conveying cargoes. It can also be used at places where electric power is not available. Features: 1. Safety in use and convenience in maintenance. 2. Compact in construction and small in dimension. 3. Span between wheels can be conveniently adjusted and is suitable for various "I" shaped steel beam. 4. Left and right side plates are of hinge-joint construction and their heights can be automatically adjusted under pressure, and as a result, tension can be evenly distributed onto all four wheels. 5. High efficiency in transmission and minimum hand-pull and can travel on bends of small radius. Points to remember when using: 1. Overload strictly prohibited. 2. When lifting heavy pieces, no passage or working underneath the heavy pieces being lifted up is allowed. 3. When lifting heavy pieces, make sure that the center of gravity of the heavy pieces be within the plane of the web plate of the "I" shaped steel beam. Otherwise no lifting is allowed. 4. When pulling the chain, make sure that the tension received by the chain be within the plane of the center of the hand wheel. No pulling from sideways is allowed. 5. If the operator feels something abnormal when pulling the chain, make sure that he shall not pull any further with all his might. What he should do is to stop the operation immediately and check. 6. Lubrication should be done to the gears and the rails regularly and meanwhile check and make sure that all fastening parts are not loose. 7. This trolley's operation is realized
