Overhead Crane Work Levels Classification

2021-06-112017-09-28 by ellsodov

Overhead Cranes are intermittent machines that feature short and repetitive work. At work, the crane when the institutions open， it can stop immediately. Sometimes it can turn, while sometimes it can also be reversed. Some cranes work day and night, and some work once only, and some even work only a few times a day. This working condition shows that the crane and its agencies are working differently. At the same time, the load on the crane is also changing, and some cranes are often loaded, and some often only hanging light load, the load situation is very different. In addition, due to the different speed of the various agencies, the impact of dynamic impact load is also different.

This work characteristic of the crane must be taken into account when designing the crane parts, the metal structure and the determination of the crane power. Today, as a major technical parameter of a crane is the working level of a crane, which replaces the unreasonable working system of the past. The size of the work of the crane level is determined by the two types of capacity, one is the use of heavy cranes, known as the crane use level; the other is the size of the crane to bear the load, known as the crane load state. The crane has a certain total number of cycles during the active life. The working cycle of the crane operator is the entire process from the start of the lifting of the item to the next lifting of the item. The total number of work cycles represents the degree of utilization of the crane, which is one of the basic parameters of the crane grading. The total number of work cycles is the sum of the number of cycles of the crane during the specified service life.

The crane must be equipped with the qualified fire extinguishing. When fire, you should immediately cut off the power, use the insulation fire extinguisher to put out the fire.
When the crane has an electrical fault, it should be repaired by an electrician.
TheThe working light used for repair should be under 36V. The rated capacity of each fuse (piece) shall not exceed the specified value, and it must not be arbitrarily increased, not allowed to use the other wire (piece) instead.

Regular Inspection Work Ensures a Safe and Efficient Work

Crane running mechanism is equipped warning and alarm, check they are good when starting to work. Check whether the terminals of lifting steel wire rope are firm before starting, and they must be without bend and squeeze. Check whether each contactor is intact, the limiter switch is complete, the location is correct. Check whether wire and cable are without damage, each operating handle is intact. Check whether walking track has obstacles or not.
Check whether a contractor, limited switch, and brake are flexible for a no-load run. It can be put into operation after making sure that each mechanism is reliable.

Pay attention to the hook lifting height to prevent the accident from lifting over the limit device.
No climbing the bridge crane when it is moving.

What does the overhead crane driver should do for his own safety facility?
