Heavy duty overhead crane, also called large overhead crane, this overhead equipment used widely on construction site, industry, factory. Most of heavy duty overhead cranes are double girder type, if you want to save cost and plant space, you can choose a high quality single girder crane that is able to lift large duty loads. This crane has a better performance than common equipment, it can lift loads around 100 tons, some high working class crane can lift capacity more than 400 tons. We provide you standard crane weight from 0.5 tons to 70 tons. if you have any exceptional lifting need, we can make your non-standard overhead equipment.

Heavy duty overhead cranes have heavier rated capacity and used on more busy occasions, so the safety of this large crane is very important. Here overhead equipment is going to introduce some little thing that concerns a lot of the safety of overhead crane. For traditional double girder heavy duty overhead crane, travel switch takes little space on the overhead bridge crane configuration, of course, it is also the cheapest part. However, new type overhead crane pays much attention and technology on travel switch. Here are the meaning why we use high cost strong strength switch.
The changing is because an accident. Some of overhead crane may have problem on the direction for hoist trolley test by our engineer, and sometimes it just cannot move. And the other action are no problem. You may think that hoist trolley is run out of power, but the other movement is smooth. So it is not the problem. After many times test, engineers find that problem happens because of the limit of travel switch. Bending amplitude of limit ruler is small, so the connection of travel switch is not good. And the limiter ruler belongs to non-standard product, it relies on the technique of operator. If the operator has less experience, then the limit ruler may have the same problem.
In order to solve the problem caused by human, excellent manufacturer uses photoelectric switch or cross fork type switch. Though the price is higher than transitional LX1012B switch, it doesn’t need a limit ruler. So operator cannot influence the angle or size, and without the influence, your overhead crane can be more safe.
