Background

The size and the weight of a rotor in a large hydroelectric generating set are usually large, some rotors even reach 2000T, and when the large rotor is hoisted, a single bridge crane is very difficult to hoist. At present, each large hydroelectric power plant is generally hoisted in a way of combining two bridge cranes. Namely, the two bridge cranes operate independently and do not influence each other at ordinary times. When the rotor is hoisted, the two bridge cranes are parallelly connected by adopting the balance beam and the connecting rod, so that the two bridge cranes work cooperatively, and the hoisting work of the large rotor is realized.

When the bridge cranes are combined, the bridge cranes are usually connected by connecting rods with the diameter of 150mm because the main beams of the bridge cranes are spaced by about 3 m. The connecting rod is about 3.5m long and weighs about 500 kg. When the bridge machines are connected, the connecting rod is placed on one of the bridge machines and then penetrates through a gap of about 3m between the main beams of the two bridge machines. In the process of installing the connecting rod, because the length and the weight of the connecting rod are large, and no hoisting tool is arranged on the connecting rod, the installation process is completely installed in a manual mode, so that the connecting rod is easy to fall when passing through the neutral position between the main beams, and great potential safety hazards are caused.
