How to inspect the working device of electric forklift?
As we all know, the working device of electric forklift is very important, including gantry, chain, pulley, etc. They control the lifting and lowering of goods and affect work efficiency and quality. Once the working device of the electric forklift has problems, it will bring many troubles to the driver's work. Then, how to inspect whether the working device of the electric forklift meets the requirements? Whether it is a cheap forklift or not, we can get twice the result with half the effort by following the instructions of the electric forklift manufacturer.
First, let's see how to inspect the chain and pulley of the electric forklift. As required, the chain piece of the electric forklift shall be free from cracks and deformation, shall be able to rotate flexibly. The elongation of every 20 links shall not exceed 8mm. The wear of the chain pin shall not exceed 5% of the original diameter, and there shall be no serious bending, cracking and corrosion. If the above problems occur, replace them in time. Look at the pulley. If uneven wear occurs on the surface of the pulley, the outer diameter difference between the two pulleys is greater than 0.2mm, and the pulley surface has indentation, which affects the normal operation of the chain. Whether it is a cheap forklift or not, it should be replaced in time.
Then let's take a look at how to inspect the internal and external mast of the electric forklift. According to the regulations, the internal and external portal frames shall be straight, and the straightness error within the full length shall not exceed 1mm, and the maximum shall not exceed 3mm, otherwise they shall be inspected. Use magnetic flaw detection and tapping method to inspect whether there are cracks, deformation and distortion. If the bending deformation exceeds 1.5mm in the full length range, the transverse width exceeds 1.5mm, and the bending deformation of the top plate of the inner mast exceeds 2mm, it shall be corrected. Local deformation or concavity and convex of internal and external portal frames shall be corrected with flame, and the temperature shall be controlled at 700~800 ° C. If the overall deformation and corrosion are serious, whether it is a cheap forklift or not, it will be scrapped.
The above is the inspect method of the working device of the electric forklift. The manufacturer of electric forklifts reminds everyone that whether it is a cheap forklift or not, they should follow the methods provided by the electric forklift manufacturer, carry out regular inspections and maintenance, and solve the problems that may occur in advance, so as to avoid affecting work efficiency and saving costs.

New energy forklift power system controllerIn the electric forklift power unit, when the forward contactor is closed, the motor is in a forward rotation state; Whereas, when the reverse contactor is closed, the motor is reversed. By changing the direction of the armature current or excitation current, or by changing the polarity of the excitation winding, the commutation control of the motor is realized. However, the use of two sets of excitation windings with opposite windings will lead to a complex structure and an increase in the volume of the motor, so the first two methods are more commonly used in practicalDo you like ?0

Electric forklifts vs. internal combustion forkliftsHowever, there are also some drawbacks to internal combustion forklifts. First of all, diesel engines are more expensive to run, especially against the backdrop of the current surge in oil prices. Secondly, the internal combustion forklift is noisy and vibrate, and the operating noise of the diesel engine has an irreversible impact on the human body. In addition, the exhaust gas pollution is serious, even if the processor is installed, it will cause environmental pollution, and it is necessary to clean up the dust regularly, which is more cumbersome to maintain, and can easily lead to oil pollution problems on the site.Do you like ?0
