What is the lowest cost warehouse lift truck?

The DC motor is an important component of the electric stacker . Although AC motors are very popular, DC motors are still widely used today. The faults of DC motors can be divided into electrical and mechanical faults. Electrical failures mainly occur in the winding, commutator, and brush parts. Mechanical failures mainly occur in the bearing part. Next, the stacker manufacturer  will explain in detail what common faults exist on the DC motor of the electric stacker. The first common fault is that the motor of the electric stacker  cannot rotate. This problem may be caused by the following reasons: the power supply does not have voltage or the power supply is not connected; Poor contact between the brush and the commutator; Due to the excessive size of the brush, there is no contact between the brush and the commutator; There is a short circuit or grounding in the armature winding and excitation winding; Excitation winding wiring error; The bearing is too tight causing the arm...

  The failure of the traveling circuit of the electric stacker  is manifested as a phenomenon of not running, and the failure of not running should focus on three aspects: the operating circuit, the control circuit, and the main circuit. The operation circuit mainly solves the problem of whether the reversing contactor can be closed or not. The control circuit mainly solves the problem of whether there is a thyristor control signal. The stacker manufacturer  told everyone that the main circuit is to solve the problem of whether the traveling motor can be powered on. First of all, the manufacturer of the electric stacker  will explain how to check the operating circuit of the electric stacker car. The operation circuit mainly includes power switch, seat or handle switch, brake switch, start switch, contactor coil, etc. During inspection, it is necessary to first determine whether there is a pickup sound from the contactor. If there is a pickup sound, it indicates that...

Drive and control systems are very important for any mechanical equipment or vehicle. The same is true for electric stacker . The development of the drive and control system for electric stacker is reflected in two aspects: the drive motor and the control system.

The stacker manufacturer told you that the battery is very important for the electric stacker . It is an important source of power for the electric stacker. On the battery, a very important part is the plate. The electrode plate may not be known to you. It is divided into positive plate and negative plate. It is a lamellar porous body composed of active substances and "collector" for supporting and conducting. Regardless of the forklift  price , if there is a problem with the plate, the normal operation of the battery will be seriously affected. Among them, short circuit is a very easy problem for the plate. What should I do if the battery of the electric stacker is short-circuited? The stacker manufacturer came to talk to you in detail. First of all, let's see how to judge whether the battery of the electric stacker  is short-circuited. It generally has several performances. The first is that the open-circuit voltage is relatively low. The second performance is...

Pallet is a very important logistics storage facility. It is generally used with electric forklift such as electric stacker  and electric pallet jack to play a huge role. It can make goods mobile and ready for movement at any time, which greatly facilitates handling and stacking. However, if the electric stacker is operated improperly, it is likely to damage the pallet, affect the work efficiency, and even damage the goods. How to prevent the electric stacker from damaging the pallet? The electric stacker manufacturer  will tell you something. First of all, the precondition to prevent the electric stacker  from damaging the pallet is to move slowly. Reducing the speed when handling, stacking and forking goods can not only give drivers more time to think about how to handle goods correctly and reduce errors, but also prevent gantry, elevator, etc. from violently hitting pallets or goods. Secondly, overload or eccentric load shall not be allowed. The carrying capacity ...

Electric stacker  is mainly used for short distance transportation, loading and unloading and stacking of goods. Before transporting goods, enterprises and drivers should pay attention to many problems, such as the placement of goods during loading and unloading, because we know that if there is a problem with the placement of goods, it is easy to have security problems. Then, we need to pay attention to many aspects. Next, the electric stacker manufacturer  will take you to know what problems should be paid attention to when loading and unloading goods. No one is allowed to stand on the electric stacker  when it is running. When stacking goods, the driver should pay attention that the fork tip should not touch other goods to avoid damage to the goods. The correct method is to insert the fork deeply under the goods, and adjust the distance between the two forks as required, so that the load of the two forks is balanced and will not deflect. The electric stacker manufactur...

Electric stacker  is a logistics storage equipment for lifting, stacking and short distance transportation of goods. In recent years, it has become popular and its sales volume has risen sharply. Compared with other stacker trucks, it is more efficient, time-saving and labor-saving. However, many enterprises that are willing to buy do not know how to express clearly, although they have many requirements and questions when consulting the electric stacker manufacturer. This is mostly because enterprises do not understand the terms of electric stacker, so it is hard to say. Now, the electric stacker manufacturer  will popularize the terms of electric stacker for enterprises. First, let's talk about the most important term, the rated load of the electric stacker . It refers to the maximum weight of the cargo allowed to be lifted when the distance from the center of gravity of the cargo to the fork forearm is not greater than the load center distance. To put it simply, it can tell ...

As a common logistics transport vehicle, electric stacker  also inevitably has some small failures. In order to become a qualified driver of electric stacker, it is necessary to learn how to judge the cause of the fault and solve it successfully. Then, the professional electric stacker manufacturer  will tell the drivers what are the common small faults of the electric stacker, and how to troubleshoot and repair them in the future. If the speed of the driving wheel of the electric stacker  drops significantly, it may be caused by the following reasons: the voltage in the battery is too low or the resistance is too high; Carbon deposits between motor commutator blades cause short circuit; The motor brake is not adjusted properly, causing the motor to run with brake; Motor armature is short circuit; The gear box and bearing of the drive head are jammed and need lubrication urgently. When encountering such problems, the driver can check and repair in the following ways: meas...

The stacker is a wheeled carrier used for loading, unloading, stacking and short distance transportation of goods. It can be divided into semi electric stacker, electric stacker  and manual hydraulic stacker.

Electric stacker  is a kind of storage equipment with battery power as the energy source and motor as the power source. It is composed of battery, motor, hydraulic pump, oil cylinder, piston and other components. Among them, the oil cylinder is the part that converts hydraulic energy into mechanical energy, which is very important for the electric stacker. However, oil leakage is a common problem of electric stacker, which gives many drivers a headache. In case of oil leakage from the electric stacker, don't worry. The electric stacker  manufacturer  will explain how the electric stacker leaks oil and how to solve it. The oil leakage of the electric stacker  may be due to the wear between the valve stem and the valve body. If the distribution valve is frequently used with high intensity or the oil is not clean, the wear between the valve stem and the valve body will be increased. This may damage the mating sealing surface and cause oil leakage. If the wear is not too...
