The forklift has changed from the previous fuel to the current electric forklift, which brings many conveniences to our lives. Some drivers find that after long-term driving, electric forklifts will make noise after a period of time. How is the noise of the forklift generated? What precautions should be taken to operate the clutch to avoid noise? The following is a detailed introduction for everyone. a. Reasons for noise problems of electric forklifts 1. Check whether the conflict between the guide wheel, the roller and the mast is too large. Whether the cooperation gap between the fork and the fork frame crossbeam is too large, these factors will cause the electric forklift to produce greater noise during use. 2. The gap between the chain and the pin of the chain pin is too large, or the gap between the upper and lower staples of the fork and the crossbeam of the fork frame is too large. 3. Loose fasteners, severe wear of the guide wheels and rollers of the car body, resulting in a large gap. b. Matters needing attention 1. When the electric forklift is not using the clutch, do not put your feet on the clutch pedal to avoid the semi-linkage phenomenon of the clutch, affect the power transmission, and aggravate the wear of clutch plates, clutch bearings and other mechanical parts. 2. No matter whether it is high-end downshifting or low-range upshifting during driving, it is forbidden to shift the clutch without collapsing. 3. Frequently check and maintain the clearance between the separation lever and the separation bearing, and check and lubricate the clutch separation bearing, seat and sleeve on time. There are many reasons for the noise caused by electric forklifts. The staff should drive the forklift to the parking lot facility for special investigation and find the reason, so as to solve the doubt of the forklift noise from the source. The staff should pay attention to the operation and try to avoid it Noise generation.

The unmanned forklift has the advantages of accurate positioning, no infrastructure, independent programming, and flexible operation. Its navigation uses remote control technology, which not only saves labor, but also effectively prevents the occurrence of dangerous accidents. Currently, the two mainstream navigation methods are based on SLAM environment natural navigation and reflector navigation. 1. Reflecting plate navigation principle: Reflecting plates are arranged at a certain distance around the driving route of the forklift. The laser scanner on the forklift emits laser beams. These laser beams can quickly collect the laser beams reflected by the reflecting plate. Based on the data of multiple laser beams reflected back, the current position and course of the forklift in the environment can be determined, and in conjunction with the motion controller control algorithm, the forklift can be driven automatically. 2. Natural navigation based on the SLAM environment: SLAM is simultaneous positioning and mapping. In an unknown environment, the robot positions itself through the internal sensors and external sensors carried by itself, and on the basis of positioning, uses external sensors to obtain Environmental information, incrementally build an environmental map.

Electric forklifts mainly carry cargo in a fixed space, so how to drive an electric forklift? What is the specific method of use? Let's listen to the introduction of electric forklift manufacturers. Instructions for use of electric forklifts: 1. Depress the clutch pedal, start the engine, gradually refuel to raise the temperature of the engine, properly operate the multi-way valve, and lift the fork off the ground by about 15-20CM. 2. Switch to low gear, choose forward or backward gear, gently lift the clutch, slowly increase the throttle, and the forklift starts. 3. Alignment. Go to the pick-up place, slow down the speed, adjust the height and level of the fork, lightly step on the clutch, semi-linked. Adjust the direction until all forks fork into the goods, refuel to lift the forks, 15-20CM away from the ground. 4. When moving the forklift, the speed should be slow, the truck should be stable, and brakes should be used less. 5. Delivery. When the forklift arrives at the place where the goods are placed, slow down the vehicle and move the joystick gently. After the goods are stabilized, the forks can be emptied before returning. The above is the specific method of opening the forklift. In addition, in the process of use, it should be flexibly operated according to the actual situation. Before operating, be sure to understand the operation manual of the forklift and understand some common faults.

Doing good maintenance and maintenance of electric stacker trucks can effectively improve work efficiency and greatly liberate manpower. Here is a brief introduction to electric forklift manufacturers: (1) Cleanliness and sanitation of the use site. (2) When servicing, please take off your watches, earrings or other ornaments, and do not bring loose or valuable items on your body to avoid falling into the electric stacker. Especially when repairing the electrical system of the electric stacker, if the metal contacts the energized electronic components, it is easy to cause short circuit or burning. (3) Before maintenance, unplug the power socket of the electric stacker and disconnect the power supply. (4) Before opening the cover or electrical system, turn off the key switch of the forklift. (5) Before checking the hydraulic system, the fork should be lowered and the system pressure should be released. (6) Check the oil leakage of the car body, wipe it with paper or cardboard, and do not touch it directly with your hands to avoid burns. (7) Before changing gear oil or hydraulic oil, let the electric stacker truck cool down first, because the oil temperature in the transmission or hydraulic system may be higher to prevent the high oil temperature from causing combustion. (8) Store and discharge oil according to regulations, and do not discharge it to sewer pipes casually. (9) When welding the car body, disconnect the battery power supply. Otherwise, the welding current may enter the battery during welding, so it is important to cut off the battery. (10) If working under the stacker truck, the electric stacker truck should be supported by a bracket. Improper support, the electric stacker will tip over and hurt people. (11) Fill the hydraulic system with new cleaning oil. If the hydraulic oil is not clean or hydraulic oil of different brands is used, it will affect the precision hydraulic components and reduce the capacity of the entire hydraulic system. It is recommended to use uniform grade hydraulic oil. The above is the maintenance and maintenance method of the electric stacker. Doing a good job in maintenance can not only improve the logistics handling efficiency, but also effectively extend the service life of the product.

(1) What is a three-pivot electric forklift? The three-fulcrum type counterbalanced seated electric forklift is abbreviated as the three-fulcrum electric forklift. It is an electric forklift whose rear wheels are both driving wheels and steering wheels. This type of forklift has a small load on the rear wheel axle due to the load in the front, so the motor power required by the drive system is small, the fully enclosed AC technology is adopted, the structure is compact and simple, and the turning radius can be obtained with a small turning radius. There is enough grip on the slippery ground. The three-pivot electric forklift does not drive the front axle, the mast is directly connected to the front wheel as a whole, the upper part is connected to the frame, the lower part of the mast is connected to a tilting cylinder arranged at the bottom of the car body, and the oil is supplied through the hydraulic system. The piston rod moves back and forth. The mast and the front wheels rotate around the hinge axis on the frame. Extend or retract the bottom to achieve backward or forward tilt. At the same time, the wheelbase of the vehicle is extended or shortened. (2) What are the advantages of the three-fulcrum electric forklift? 1. Shorten the front overhang of the vehicle. With the same tonnage, the required counterweight is light, the vehicle length is shortened, the turning radius is reduced, and the maneuverability is good. 2. When the cargo is in operation, the mast tilts backward and the wheelbase extends. The stability is improved, and the driver can operate the forklift more safely and smoothly. 3. The traction performance is more superior because the center of gravity moves back as the track length increases. The rear wheel load is increased. When the full-load mast tilts backward, the rear wheel load can be increased to about 54% of the original rear wheel full load load. Since the rear wheel load is within a small range, the traction force is determined by the rear wheel adhesion. The increased load on the rear wheels undoubtedly improves the traction performance. 4. Increase the working hours of each class. Due to the small counterweight and light weight of the whole machine, energy can be saved. 5. When the wheelbase is shortened, it can improve mobility and increase the use of storage space. The forklift truck adopting this structure can work in a narrower aisle than other forklift trucks. In short, the three-fulcrum electric forklift is a forklift with flexible use and compact structure, which has a wider use field and a long life.

The normal operation of electric forklift trucks is inseparable from the participation of electric motors. Electric forklift truck manufacturers remind forklift drivers that it is necessary to understand in advance: common faults of electric forklift motors. 1. Cannot start. It may be that the electric forklift's motor has a fuse blown, the control circuit is not open, the motor winding has a serious short circuit or open circuit, a short circuit between the commutator blades, poor brush contact, overload, or mechanical damage such as bearings. 2. The speed is abnormal. It may be caused by short-circuit or open circuit of the winding, incorrect and overloaded brush position, bearing damage, and low power supply voltage. 3. Sparks from the brush. It may be caused by poor contact of the brushes of the electric forklift, unevenness of the surface of the commutator, unclean surface of the brush, incorrect position, short circuit of the commutator or short circuit of the motor winding. 4. There is noise. The bearing parts of the forklift are damaged, the surface of the commutator is uneven, and the vibration or friction of the brush is caused. 5. Generate high temperature. Due to overload, the bearings and oil seals of the forklift are too tight, damaged or poorly lubricated, the shaft core is not correct, the armature and the magnetic pole phase friction, the winding short circuit, the brush pressure is too large, the position is not correct, and the rectification is caused.

In the field of logistics, electric forklifts and diesel forklifts are often used. They are similar in shape, but the price is very different. Why are electric forklifts more expensive than diesel forklifts? According to electric forklift manufacturers, this mainly depends on the engine. What is the engine? It can transform other forms of energy into mechanical energy, and it is the heart of an electric forklift. Although the frames of electric forklifts and diesel forklifts are basically similar, their power is different. The power source of diesel forklift is diesel engine and gearbox, while the basic power mechanism of battery forklift is motor, gearbox, battery and controller. The internal combustion engine developed early, the technology is relatively low, and the price is low. Most controllers for battery forklifts are imported. The battery price is also relatively expensive. The circuit board price is also higher than that of diesel forklifts. Overall, the cost of accessories is much higher than diesel forklifts. This determines that electric forklifts are more expensive than diesel forklifts. The sales volume of diesel forklifts is much higher than that of electric forklifts. The output is large and the purchase cost of individual parts is low. Although the sales volume of electric forklifts has been increasing, diesel forklifts can be produced in large quantities and the price is naturally very low. It is difficult for battery forklifts to achieve mass production. , So electric forklifts are more expensive than diesel forklifts. Although current sales of electric forklifts are not as good as diesel forklifts, and the price is more expensive than diesel forklifts, it is simple to operate, has low maintenance costs, and has a long life, more efficient and environmentally friendly, and will gradually replace diesel forklifts in the future.
