Large crane is mainly used for loading and unloading and transfer of materials, is the primary production of modern equipment. The use of lifting transport machinery, can reduce the labor intensity, reduce loading and unloading costs, reduce the damage to the goods, improve labor productivity, Big Crane Claw Machine the end of the production process mechanization and automation is not a short machine equipment. So it is widely used in factories, mines, ports, stations, construction sites, power plants and other production areas. Large cranes are mechanical equipment that are intermittent, repetitive, lifting, lowering, or lifting and moving heavy loads by lifting hooks or other spreaders. Big Crane Claw Machine Its work characteristics are cyclical. In each working cycle, its primary organization makes a positive and reverse movement, each cycle contains the loading and unloading of items, the transfer of items of work and unloading after the empty hook return, before and after the two loading between There is a short stop with the help of the preparation time.
Summarize the working characteristics of large cranes, Big Crane Claw Machine from the perspective of security skills analysis, can be summarized as follows:
(1) Large cranes usually have a huge structure and a messy organization that can end a lifting movement, one or several horizontal movements. Work process, often a few different directions of movement with the operation, skills more difficult.
(2) the lifting of the heavy variety, Big Crane Claw Machine the load is changed. Some heavy weight of several hundred tons or even thousands of tons, and some objects up to tens of meters, the shape is very irregular, so that the process of hanging and the risk of clutter.
(3) most of the large cranes, the demand in a larger range of operation, and some to install trajectories and wheels (such as tower crane, bridge crane, etc.), and some to install tires or crawlers walking on the ground (such as car cranes , Crawler cranes, etc.), and the need to walk on the rope (such as passenger, cargo aerial ropeway), the event space is larger, once the impact of the incident area is also larger.
(4) some large cranes, the demand for direct carrying personnel in the rails, channels or wire rope to do lifting movements (such as elevators, lifting channels, etc.).
(5) exposed, the activities of the more parts, and often with the lifting of the staff directly touch (such as hooks, wire rope, etc.), Big Crane Claw Machine potentially a lot of occasional risk factors.
(6) work environment messy. From large steel joint enterprises, to modern ports, construction sites and so have a large crane in operation; often encounter high temperature, high pressure, Big Crane Claw Machine strong magnetic and other risk factors, equipment and staff posed a threat.
(7) work often require more people to work together to carry out an operation, ask the command, strapping, driving and other staff cooperation skill, action coordination, mutual care, the staff should have the ability to deal with on-site emergency situation. The close cooperation between the many staff, Big Crane Claw Machine there is a big difficulty.
It is precisely because of the impact of many of the above factors, lifting and causing more trouble, so the use of lifting equipment must be strictly safe and safe, as far as possible to reduce the incident. Enterprises should be punctured on the lifting equipment to eliminate security risks.
