The daily maintenance of the wire rope electric hoist crane is the key to ensuring its normal operation and extending its service life. Here are some suggestions for daily maintenance and upkeep of wire rope electric hoist cranes:

1、 Maintenance and upkeep of steel wire rope

Correctly open and cut the steel wire rope:

Steel wire ropes are usually packaged in coils when they leave the factory, and should be opened correctly to avoid twisting or knotting.

When cutting the steel wire rope, measures should be taken to prevent the rope strands from scattering.

Installation and Protection:

When installing steel wire ropes, avoid dragging them in unclean areas and do not wrap them around other objects to prevent scratching, grinding, crushing, and excessive bending.

During daily storage, precautions should be taken to prevent damage, corrosion, or other physical or chemical reasons that may cause a decrease in performance of the steel wire rope.

Daily inspection:

Check the fixed connections at the end of the steel wire rope, the balance pulley, and the wear condition every day, and make a safety judgment.

Pay special attention to checking for broken wires and whether the wear of the steel wire rope exceeds the specified standards.

Lubrication and Cleaning:

The lubrication status of the steel wire rope should be checked regularly and lubricated regularly, usually at least twice a month.

Regularly clean the steel wire rope by first using a wire brush to remove dirt, then cleaning it with kerosene, and then dipping it in lubricating oil heated to above 80 ℃ to ensure that the lubricating oil is immersed in the rope core.

2、 Maintenance and upkeep of other critical components

Brake:

Check the wear of the brake pad pad, which should not exceed 2mm, and the contact area between the pad and the brake wheel should not be less than 70%.

Check the installation and fixing condition, wear and lubrication condition of each pin shaft to ensure that the wear does not exceed 5% of the original diameter.

a hook:

Check whether the hook has cracks and whether the wear of its dangerous section exceeds 5% of the original thickness.

Check if the anti loosening device of the hook nut is complete and if all parts on the hook assembly are complete and reliable.

Ensure that the hook rotates flexibly without any jamming.

Electric motor and reducer:

The bearing parts of the electric motor should be regularly lubricated with lubricating oil.

The gear oil inside the reducer should be replaced regularly.

Other components:

Check all bolts for looseness or shortage.

Regularly check whether the slider on the drum is stuck.

The various pin shafts inside the brake should be regularly lubricated with butter.

The protective cover installed on the motor shaft must be kept intact and operate flexibly and reliably.

3、 Precautions for use

Overloading is prohibited: It is absolutely forbidden to use it in environments that do not allow it, and in situations where it exceeds the rated load and rated closing times per hour (120 times).

Safe operation: It is not allowed to press two manual switch buttons at the same time that cause the electric hoist to move in opposite directions. After the work is completed, the main switch of the power supply must be opened to cut off the power.

Regular inspection: Special personnel must regularly inspect the electric hoist, take timely measures if any faults are found, and carefully record them.

Lubrication and Cleaning: Maintain sufficient lubricating oil and keep it clean, without impurities and dirt. When oiling, a hard bristled brush or small wooden pieces should be used, and it is strictly prohibited to directly oil the working steel wire rope by hand.
