Single-arm crane is a kind of lifting equipment that uses a single column and a rotary arm to lift goods. The lower end of the column of the single-arm crane is generally fixed on the foundation of concrete, and the rotary arm can be rotated according to the needs of customers. The single-arm crane has the advantages of simple structure, convenient operation and large working space. It is widely used in the production line and assembly line of various factories and mines. It is an energy-saving and efficient material lifting equipment.
Safety technical operation specification for 2T single-arm crane
I. Single-arm lifting weight is 2T, it is strictly prohibited to exceed this weight.
2. The personnel of the outside unit shall not use the equipment without the permission of the district mechanical and electrical team, otherwise all accidents will be taken responsibility by themselves.
Three, the operator must hold a certificate to work, is strictly prohibited to drive without a license, before driving carefully check the winch brake is flexible and reliable, each part of the lubricating oil is sufficient. Whether the wear of the wire rope exceeds the limit, whether the rope head is fixed firmly, when the wire rope is found out of the pulley, it must be reset immediately, and check whether the ground anchor, hook, lifting arm, lifting chain is damaged.
