The operation of blocking up the screw steel of 9m or 12m is generally carried out by using double 25t forklifts at the port at present, and 3 bundles of screw steel are simultaneously forked by two forklifts to about 9 tons. In the later stage of the blocking operation, the screw-thread steel is already installed in the cabin, so that the forklift cannot normally run in the cabin, and in order to ensure the normal operation of the forklift, a steel plate needs to be paved on the already-installed screw-thread steel. The steel plate is generally perforated at the periphery, four lifting hooks and steel wires are used for hoisting, then the steel plate is basically paved on the threaded steel in the middle of the cabin, the forklift runs on the steel plate for operation, and two forklifts simultaneously hold three bundles of threaded steel for synchronous operation, so that requirements on commanders and forklift drivers are higher, and the risk coefficient of the blocking operation is high, the operation cost is high, and the operation efficiency is low.
