What are Electric Stackers?

Electric stacker is a kind of storage equipment which uses battery power as energy source and motor as power source. The main structure includes: battery, motor, hydraulic pump, oil cylinder, piston rod, fork, chain, controller and other devices.

Electric stacker

Electric stacker is

1. Pallet stacker with bottom legs in front of the stacker. It is suitable for loading and unloading of national standard single-sided pallets or palletless goods.

2. Wide leg stacker truck. The front leg of the stacker truck is wide. Generally, the inner width is 550 / 680mm. The wide leg can be 1200 / 1500mm. The double-sided tray can be installed and removed , Limited to within), the advantages are moderate in price, which can solve double-sided trays or some special goods

1. Before driving, check the working conditions of the brakes and pumping stations, and ensure that the battery is fully charged. Hold the joystick with both hands and force the vehicle to slowly move towards the work load. If you want to stop, you can use the hand brake or foot brake to stop the vehicle.

2.Unloading

(1) With the fork low, keep it vertical to the shelf, carefully approach the shelf and insert it at the bottom of the pallet.

(2) Retreat the stacker to move the forks out of the pallet

(3) Raise the fork to the required height, and slowly move it to the pallet to be unloaded, while ensuring that the fork easily enters the pallet and the goods are in the safe position of the fork

(4) Lift the fork until the pallet is lifted from the shelf

(5) Slowly retreat in the passage

(6) Slowly lower the cargo while ensuring that the fork does not touch the obstacle during the lowering process

Note: During cargo lifting, steering and braking operations must be slow and careful.

3. Stacking

(1) Keep the goods low and approach the shelves carefully

(2) Lift the goods above the shelf plane

(3) Slowly move forward, stop when the goods are above the shelf, lower the pallet at this point and pay attention that the fork does not apply force to the shelves under the cargo to ensure that the cargo is in a safe position

(4) Slowly retreat and ensure that the pallet is in a firm and secure position

(5) Lower the fork to a position where the stacker can travel

4. Safety facilities

(1) Main switch: power main switch

(2) Foot brake: reliable parking brake

(3) Restriction valve: control the descending speed

(4) Pressure limiting valve: control load

(5) Protection net: protect the driver

5. Prohibited matters

(1) It is forbidden to operate a semi-electric stacker after drinking.

(2) Prohibition of overload, uneven and flat stacking of goods

(3) Riding operation is prohibited

(4) Do not park on ramps or steps.

There are many precautions for the safe operation of electric stackers. The following Nuoli forklifts provide some useful suggestions to major users as follows:

1. Operators of electric stackers are not allowed to drive under the influence of alcohol, overweight, high speed, and speeding. It is forbidden to brake or turn sharply. Do not allow stackers to enter the place where solvents and flammable gases are stored

2. The safety device of the electric stacker must be complete and intact, each component is sensitive and effective, and the technical performance is good.

3. Maintain the standard driving status of the stacker truck. When the forklift is off the ground, the forklift is 10-20 cm off the ground. When the stacker truck stops, it drops to the ground and drives around. When operating on a poor road, its weight is appropriately reduced. The travel speed of the stacker should be reduced.

4. When the electric stacker is running, if the electric controller is out of control, disconnect the main power supply in time.

5. In the use of electric stackers, special attention should be paid to the timely charging of batteries and the correct maintenance of batteries. Pay attention to the method when charging the battery, not only to make the battery fully charged, but also not to cause the battery to overcharge.

6. In the operation of the electric stacker, use as little acceleration as possible for a long time. When the stacker starts and the speed increases, stabilize the accelerator pedal. If the road conditions are better, the stacker will continue to accelerate. When the stacker needs to decelerate, loosen the accelerator pedal and gently depress the brake pedal. This can make full use of the deceleration energy. If the stacker has a regenerative braking function, the kinetic energy during deceleration can be recovered. When the vehicle is descending on a slope, do not disconnect the circuit of the drive motor of the stacker, and gently depress the brake pedal to make the stacker run in a regenerative braking state, and use the kinetic energy of the vehicle to reduce the energy consumption of the battery.

7. During the operation of the electric stacker, do not mistake the forward and reverse direction switch as a steering switch. Unless an emergency deceleration is required, do not press the brake pedal all the way down. During the operation of the vehicle, when the battery is found to be insufficient (available through the power meter, power failure indicator and other alarm devices), the battery should be charged as soon as possible to prevent the battery from being over discharged.

8. During the operation of electric stacker trucks, do not often take emergency braking during high-speed driving; otherwise, it will cause huge friction to the brake assembly and drive wheels, shorten the service life of the brake assembly and drive wheels, and even damage them.

After the electric stacker has been running for one week, it needs to be routinely maintained. The efficiency, life and safety of the electric stacker depend on daily maintenance.

1. Safety rules for maintenance work

(1) Keep the maintenance site clean and hygienic.

(2) During maintenance, do not carry loose or valuable items on your body.

note!

When repairing the electrical system of an electric stacker, if metal comes into contact with energized electronic components, it may cause short circuit or burn. So please take off your watch, earrings or other accessories.

(3) Before repairing the electric stacker, unplug the power socket and disconnect the power.

(4) Before opening the left and right box covers or the electrical system, turn off the key switch of the forklift.

(5) Before checking the hydraulic system, the fork should be lowered to release the system pressure.

(6) When checking the oil leakage of the car body, please wipe it with paper or cardboard, never touch it by hand. To avoid burns.

(7) Please note that the oil temperature in the transmission or hydraulic system may be high. The electric stacker should be cooled first, and then the gear oil or hydraulic oil should be replaced to prevent the high oil temperature from causing combustion.

(8) The hydraulic system should be filled with new cleaning oil.

note!

If the hydraulic oil is not clean, it will affect the precision hydraulic components and reduce the capacity of the entire hydraulic system.

If different grades of hydraulic oil are used, it will damage the hydraulic components and affect the system capacity. Therefore, when adding or replacing hydraulic fluid, pay attention to the use of uniform grades.

(9) Please abide by relevant laws and regulations, protect the environment, store and discharge oil materials in accordance with regulations, and do not discharge them to sewer pipes.

(10) When welding the car body, disconnect the battery power. Because welding current may enter the battery during welding, in order to avoid this, please cut off the battery.

(11) When working under the electric stacker, the electric stacker should be supported firmly.

caveat!

Improper support, electric stacker will tip over and hurt people. If electric stacker is not protected by lifting equipment or support, it is forbidden to work under electric stacker.

2.1 Daily maintenance and safety inspection.

(1) It is the responsibility of the operator to perform routine maintenance and inspection of the electric stacker.

(2) The electric stacker does not carry out routine maintenance, which will affect the safety and reliability of the forklift and easily lead to severe

A serious accident occurred.

(3) Check for problems or find faults and immediately start repairing and stop using them.

Both belong to the narrow aisle forklift series, and they can complete stacking / stacking and picking up in a very narrow aisle (1.5 to 2.0 meters). However, the former cab cannot be lifted, so the operating field of vision is poor and the work efficiency is low. Because the latter can completely cover the functions of the former, and its performance is more outstanding, the market sales of the latter in Europe exceed the former by 4-5 times, and in China it is more than 6 times. Therefore, most suppliers focus on the development of three-way stacker trucks driven at a high position, while the three-way stacker trucks driven at a low position are only used in small tonnage and low lifting height (generally within 6 meters). When the market sales volume is very small, its service capabilities such as the number of after-sales service engineers, engineer experience, parts inventory level will be relatively weak.

After a comprehensive assessment of the impact of the above aspects, the most reasonable plan should be selected.

Precautions for use

1. Load the cargo strictly in accordance with the load curve diagram, and do not overload it;

2. Please do a thorough operation check before each use to check whether the battery is short of water. It is strictly forbidden to use the battery in the absence of water;

3. During the use of the electric stacker, it is strictly forbidden to continue to use it when it is seriously short of electricity. When the indicator of the electricity meter on the vehicle body is displayed in red, it should be charged in time;

4. It is strictly forbidden to use single forks for electric forklifts;

5. Regularly treat the interior of the car body to keep it clean.

First, the characteristics of high temperature and humidity

Under high temperature and high humidity conditions, the temperature is high and the weather is hot, which will also have a great impact on the driver's safe operation.
1. The heat dissipation performance of the engine is deteriorated under high temperature, and the temperature is likely to be too high, which makes its power and economy worse.
2. It is easy to cause the water tank to "open the pot", the fuel supply system to be blocked, the battery "depleted", the hydraulic brake to fail due to the expansion and deformation of the bowl, and the tire pressure to explode as the outside temperature rises.
3. Under the condition of high temperature and high humidity, the lubricating oil (grease) of various parts of the forklift is apt to become thinner, and the lubricating performance is reduced, which causes the wear of the parts to increase during heavy load.
4. Due to the high temperature, coupled with mosquito bites, the driver's sleep is affected, so it is prone to mental fatigue and heat stroke at work, which is not conducive to job safety.
5. There are more thunderstorms due to the road surface. There is water in the loading and unloading site, which reduces the adhesion and is easy to slide sideways, which affects the safety of forklifts, people and cargo.
2. Precautions for driving operation 1. Before entering the heatstroke period, make preparations in advance and release the winter lubricating grease from the engine, drive axle, transmission, steering gear, etc. After cleaning, fill in the summer lubricating grease as required.
2. Clean the water channel, remove the scale from the cooling system, and clear the radiator fins. Check the tightness of the fan drive belt frequently.
3. Properly adjust the generator regulator to reduce the charging current of the generator.
4. Pay attention to prevent the engine from overheating during operation. Pay attention to the indication of the coolant temperature meter at any time. If the temperature of the coolant is too high, take measures to reduce the temperature. To maintain the quantity of coolant, care must be taken to prevent the coolant from boiling and causing burns.
5. Always check the temperature and pressure of the tire, and if necessary, stop in a cool place and continue the operation after the tire temperature is lowered. Do not reduce the pressure and temperature by deflating or pouring cold water to avoid reducing the tire life.
6. Always check the braking performance to prevent the failure of brake failure caused by aging, expansion and deformation and brake fluid vaporization of the master cylinder or sub-pump bowl.
7. Adjust the density of the battery electrolyte, and clear the ventilation holes on the battery cover, keep the electrolyte 10-15mm higher than the separator, and fill with distilled water as appropriate.
8. Make sure you get enough sleep before work and keep energetic. If you feel mental fatigue, faintness, or unresponsiveness during the operation, you should stop and rest immediately, or wipe your face with cold water to cheer up to ensure the safety of driving and operation.
9, do a good job in preventing heat and cooling to prevent heat stroke.
Finally, check that all parts are in good condition before putting them into normal use. ^[1]
