Overhead Crane Maintenance Troubleshooting

   Active running gear wheels and carts frequently repeated emergency stop and parking will cause reverse gear torque of each axis, vibration increases, could easily lead to leakage.bridge gantry crane Such problems occur, the traditional method and more to be machined after welding or repair the main brush, but there are some drawbacks both: high thermal stress generated by welding can not be completely eliminated, prone to bend or break; the brush plated by the coating thickness limit is easily peeled off, and the above two methods are metal with metal repair, you can not change the "hard to hard" with the relationship, the combined effect of the force, will cause wear again. Latest repair methods mostly based polymer composites, and applications have more Wah Mei technology products, which has superior adhesion, excellent compressive strength and other performance. Applied Polymer repaired, neither welding thermal stress on the repair thickness is not restricted, while products with metallic materials do not have the concession, can absorb shock and vibration equipment, to avoid the possibility of re-wear and greatly extended equipment component life, save a lot of down time, creating significant economic value.
Crane agencies generally only four driving and driven wheels, if the starting weight is large, common approaches to reduce the wheel increases wheel pressure. When more than four wheels,overhead gantry crane a frame must be balanced hinge device, the crane load is evenly distributed on each wheel.

The metal structure of the bridge from the main beam and side beams, divided into single girder and double girder bridge bridge categories.hoist gantry crane Single girder bridge by a single span girders and located on both sides of the end beam composed of two dual-beam bridge girders and by the end beam components.
