wheel
The wheel materials of trucks are generally polyurethane, nylon, and rubber; among them, polyurethane materials are widely used in various industries because they are relatively soft and wear-resistant. Nylon wheels are generally suitable for manual pallets or semi-electric pallets because of their light weight and high hardness. The appearance rate of using rubber wheels is not very high, generally only used for the special needs of customers. The wheels must wear out because they move on the ground, so general manufacturers sell trucks without warranty. Even if it is a warranty, generally only three or six months of guarantees are provided!
Bearing
Many bearings are installed inside the wheels. When the wheels are changed, many bearings cannot be knocked off, so they are scrapped. In addition, because bearings have always been worn parts, they are basically not covered by the warranty. But generally good bearings can be used for three to five years without problems, and imported bearings can be used for more than ten years.
Oil seal
The oil seal generally acts on the piston rod of the hydraulic cylinder to play a sealing role. With the long-term friction of the piston rod, it is only a matter of time before the oil seal is worn out, so generally the oil seal is not warranted.
plastic shell
As for the plastic shell of the truck, the damage is basically caused by human operation. Of course, the probability of this occurrence is still very high. Therefore, the manufacturer also lists it as a vulnerable part and does not provide three guarantees.
Carbon brush
The motor carbon brush has always played the role of contact, but just like a pencil, it wears out all the time, so it is an inevitable trend to wear off. However, generally speaking, the carbon brush of the motor can be used for three to five years when replaced once, so although it is a vulnerable part, the frequency of replacement is not high!
Battery
At present, the batteries of electric pallet trucks are generally lead-acid battery packs; the chemical reaction inside the battery generally has an active cycle, and the general plastic shell starter battery can only be used for 1-2 years, and the iron shell is installed. The battery pack can generally be charged and discharged 700 times. Normally, it can be used for almost 3 years. Of course, better batteries such as imported batteries can be charged and discharged for 1500 times. When the manufacturer sells the truck, the warranty period given by the general battery is also 3-6 months!
to sum up
In general, wearing parts are things that have been worn out, and are things that cannot be solved at the current technical level, such as carbon brushes, batteries, etc. Of course, these vulnerable accessories are also accepted by most people!
