Today take you to see, different time, forklift trucks are prone to faults are what ?
1. Failure characteristics of forklift at the early stage of use
Forklift in the early stage of use (equivalent to go together period) its failure is from high to low (down curve), the use of the early stage of the failure rate is high or low with the manufacturing or maintenance quality and go together period of use. If the forklift manufacturing or repair quality is high, and can be properly used and maintained. Then, the initial failure rate is low. Otherwise, the early failure rate will be high.
Early failure is mostly loose or loose joint bolts; loose or loose pipe joints: residual metal chips or casting sand is easy to block the oil channel or clamped in the relative motion friction strains the machine parts (such as the hydraulic system in the actuator cylinder) caused by oil leakage, adjusted gap or pressure changes, so that the machine parts can't perform the specified capacity, some joints due to the bolts are not tight and leakage, leakage of oil, leakage of water, leakage of gas and so on.
2. Failure characteristics of forklift in normal use stage
Forklift trucks enter the normal use stage after the end of the period. Forklift operation in this stage, as long as the required maintenance and proper use, generally will not fail, even if the failure occurs, but also random failure (this kind of failure is hidden, maintenance or inspection is not easy to find), so the failure rate is very low, the curve of the curve is flat and slightly rising.
If forklift failure occurs during normal use, it is mostly accidental or due to improper use and maintenance.
3. Failure characteristics of forklift trucks close to the overhaul stage
When the forklift is close to the overhaul period, the loss of each component increases and the technical condition deteriorates.
This stage of failure is characterized by high failure rate, and common, mostly due to wear and tear and parts aging caused by the oil circuit of the blockage, leakage, bad phenomenon appears more.
4. Failure characteristics of forklifts in different seasons
Forklift failure rate is related to the season. In winter, the failure rate is higher than that in summer when the machinery is used in low temperature. For example, the fuel supply is often in the winter due to low temperatures poor atomization.
Fuel is easy to solidify the occurrence of fuel line blockage and not easy to start or engine running stalling and other faults; lubricant fluidity is poor, accelerating the wear and tear of the machine parts; battery leakage, resulting in the engine is not easy to start, braking is not reliable, the liquid transmission is not normal and so on.
