Single girder overhead crane two hoists
An electrical single girder bridge crane can be used together with two electric hoists. There are some important tips for that.
First, the capacity of two hoists can’t be over the design capacity of single girder. For example, two 1 ton electric hoists are installed on the crane, the crane lifting capacity must be over 2 ton.
Second, if the overall lifting capacity of single girder is more than 1 ton, it is necessary to have a qualified enterprise to make reconstruction operation.
Third is anti-collision device.
If these two electric hoists are far away from each other, just take travel switch or photoelectric switch to set anti-collision device.
If two hoists are near, pay attention to the closest place of load and no-load when installing fiber. For double speed, it is better to limit the fast speed first, then stop.
Fourth, if the lifting material is long, the crane can be designed to be operated by one switch or two switches.
Fifth is direction of the power supply cable. Supply the power to the crane from both sides of girder or directly by trolley line.
