​How To Extend The Service Life Of Grab Cranes?

How to extend the service life of grab cranes?

In addition to the content introduced in the article "How To Care And Maintain A Grab Crane in 2022?", I will pass you two more on how to maintain the grab crane:

1. Lubrication of running gear;

In the first application, the reducer ventilation cap should be opened first to ensure excellent ventilation to relieve internal pressure.

Before working, check whether the height-to-width ratio of the grease surface of the reducer exceeds the specification. If it is lower than the oil level, immediately upgrade the grease of the same type and specification.

During the assembly process, the bearing of each wheel of the running gear has been filled with enough grease, and it does not need to be refueled every day.

The grease can be replenished every two months through the oil filling hole or by opening the bearing cap, and the grease can be removed, cleaned and replaced once a year.

Lubricate the meshing portion of each open gear once a week.

2. Maintenance and maintenance of the reducer;

Be sure to check the lubricating oil in the gearbox to see if the oil level of the lubricating oil is within the specified range. When the oil level is lower than the specified level, the lubricating oil should be replenished in time.

In the case of infrequent use of the grab crane and good sealing conditions and operating environment, the lubricating oil in the reduction box must be replaced regularly.

If the use environment is relatively harsh, it needs to be replaced every quarter.

If the water or oil in the oil tank deteriorates, please replace the oil immediately. There are also relevant operating instructions when changing the oil.

At the same time, we must make it clear to you that the grab crane is a very dangerous special equipment, and must be operated, maintained and maintained by a special person, and must be supervised during maintenance. Requirements: (important)

1. If it is found that each limit and brake fail, it must be repaired by professional personnel before it can be used.

2. Before each use, the operator must check whether the hoisting brake is in good condition, and can work only after confirming that it is in good condition.

3. The operator must concentrate and operate carefully when operating the crane.

It is strictly forbidden for the grab bucket to collide with the lifting limit, the grab bucket to collide with the pool wall, and the lifting trolley to collide with the head on both sides.

4. After each work is completed, the grab bucket must be placed outside the pool at a low position ten centimeters above the ground, cut off the main power supply, and hang the button switch box at the designated position.

At the same time, rinse the grab bucket and add lubricating oil to each rotating part.
