Operation system of electric pallet truck

Speaking of electric pallet trucks, we have to mention his operating system. The guide rollers and rollers of the gantry, pressure roller, and fork frame are de-soldered, out of round, overrun or unable to operate. Obvious distortion, deformation, cracks and a series of problems. Next, let's take an in-depth look at the operation system of the electric pallet truck.

The lateral movement of the electric pallet truck is not flexible, and the flexibility and reliability of the positioning pins will be deteriorated. The length difference between the two forks will exceed 10mm, the height difference will exceed 5mm, and the angle between the forks will be greater than 90 or less than 88. The chain pins and guide pulleys are deformed, moved or worn beyond the limit, the chain pieces are corroded and deformed, the hasp cannot rotate freely, the adjusting screw and lock nut are not tight; it is mentioned that if the cotter pin and lock nut do not meet the requirements ; The chain is greasy; the chain is skewed or stuck. These phenomena are all detrimental to the equipment.

The running braking performance of the electric pallet truck is also very worthy of everyone's attention. If there is a problem with its performance, the equipment will have the following types of problems:

(1) The parts of the braking device of the electric pallet truck are deformed, cracked, corroded and damaged, and the brake pipelines and joints leak oil or even leak; it indicates that there is abnormal noise during braking, the stroke is large, and the braking Uneven, there will be slow separation or poor return after the brake is released, and the pressure of the pneumatic tire does not meet the standard.

(2) The transmission system is unstable, there are abnormal noises, and the gearbox is out of gear; the free travel of the pedals does not meet the standard, the steering wheel sways in a meandering manner when running, and the rear wheel is obviously pulled out.

(3) Raise the gantry to make the driving wheel off the ground, the shaking wheel will move axially, and there will be stuck phenomenon when driving the two wheels; there is a large amount of oil on the surface of the tire, which will embed hard objects , The tread wear exceeds the limit, the tires of the electric pallet truck have cracks and lumps falling off, the rubber rim is loose, and the rim is deformed.

(4) It is indicated that the brake on the foot at normal speed will not cause the phenomenon of immediate braking, the left and right drag marks are obviously inconsistent, and there is obvious unilateral braking or deviation.

(5) After the hand brake is applied, the electric pallet truck can start or drive on the runway marked with the graded grade, stop and slide, the hand brake is inflexible, and the screws of the support plate are loose.

There are a wide variety of which are scientifically tested to have positive effects on the ability to pedestrian pallet stacker. hand pallet truck pallet stacker truck is one of them.
