Summer is the peak production period for many enterprises
The use frequency of forklifts has increased significantly
In order to protect the driving safety of forklift
In addition to routine regular maintenance
Forklift safety components are also particularly important
Due to the long replacement cycle, it is often ignored by customers
Today, let's talk about "fork" and "chain"
As two important parts of forklift safety
How should I maintain it?
What are the necessary safety inspections and usage specifications
"Fork"
The two forks are like the two hands of a forklift, which rely on these iron hands to complete the heavy material handling and stacking work. Although these iron hands look solid and thick, they also need the care and care of drivers in their daily work.
Attention should be paid to the following daily operations:
■ when parking the forklift, the forklift must be completely on the ground, and the gantry must be tilted forward
■ when the forklift is driving, the height from the bottom of the fork to the ground should be kept 300-400 mm, and the gantry must be tilted back. It is forbidden to tow the fork
■ it is strictly forbidden to transport people with forks or lift people to work at heights
■ it is strictly forbidden to walk under the forks in the lifting state
■ it is forbidden to fork goods at high speed or use braking inertia to slip objects
■ it is forbidden to work with a single fork or use a fork to hold or pull objects
■ it is forbidden to unload the goods by turning the pallet with a fork
■ the fork spacing adjustment should be as stable as possible
■ the front end of the fork is uneven and cut. Do not knock it at will to try to recover, which may cause local stress concentration of the fork and cause fracture of the fork
When the fork:
Please replace it in time:
01. The fork root thickness is less than 90% of the original thickness, and the fork needs to be replaced
02. If the fork has cracks or the forward inclination angle is greater than 90 °, it needs to be replaced
03. When the height difference between the two fork tips exceeds 3% of the fork length, it needs to be replaced
"Chain"
If the fork is the two hands of the forklift, the chain is the arm of the forklift, and the lifting and unloading of materials all depend on it. The structure of this pair of iron arms is more complex than that of iron hands, so it needs more routine maintenance.
Attention should be paid to the following daily operations:
■ when the gantry is lowered to the minimum and tilted back, if the roller at the bottom of the fork frame is exposed for more than 1/3, the chain screw must be adjusted immediately
■ ensure that the tightness of the lifting chains on both sides is consistent, otherwise the chain on the tighter side bears the main load and is easy to break
■ regularly use chain spray for cleaning and lubrication. It is strictly forbidden to use butter, otherwise it will cause dust and other substances to stick to the chain and gantry and cause wear
■ remove the foreign matters on the chain in time and keep it clean. For example, use a high-pressure water gun to wash the chain. After washing, use a high-pressure air gun to remove the water between the chains
■ regularly check the chain, and the end connection must be firm without distortion and deformation, and the pitch must not exceed 3% of the length
When the following conditions occur in the chain:
Please replace it in time:
01. The chain piece of the chain must be replaced when cracks appear
02. The adjusting screw of the chain has been adjusted to the limit, indicating that the chain has been stretched to the limit and needs to be replaced
03. When the chain ruler detects that the chain elongation exceeds the safety value, it needs to be replaced
