Grab cranes are more common at the docks and have a great effect on the handling and loading and unloading of goods. Dock cranes are large-scale mechanical equipment, which has great requirements in terms of safety and reliability. Especially in the rainy season, what should be paid attention to when using cranes?

    1). Due to the special operating environment, through the operation space, the suspended object to the designated position should consist of a series of links. Once there is a problem in the middle, it may cause an accident. So every step in the middle should pay attention, it is best to have someone work together.

    2). Under normal circumstances, the load of the terminal grab is very heavy, weighing up to ton, or even hundreds of tons. It has a high potential energy in the process of lifting heavy objects suspended in the air. In the event of an accident, the high potential can be quickly transformed. For kinetic energy, the entire safety is destroyed. The operator of the remote grab should pay attention to the slow and even operation, not too urgent.

    3), in the bad weather, especially in the rainy days should pay attention to avoid affecting the line of sight, the location of the staff is also more important. No outsiders can appear around the crane's operation, and check that some parts of the crane can operate safely.

    4). Pay attention to lightning protection and check if the circuit is in good condition. Moreover, the crane will be relatively slippery when it is wet by rain, and it must be tied with a rope when lifting. If the wind and heavy rain affect the operation, stop running.
