What is Electric Stacker?
Electric Stacker is a warehouse device that uses battery power for energy and an electric motor for power. The main components include the battery, motor, hydraulic pump, oil cylinder, piston rod, forks, chains, and controller, among other devices.
Its main function is to lift heavy items to the desired height for stacking. It’s perfect for use in narrow aisles and confined spaces, making it an ideal tool for high-bay warehouses, supermarkets, and workshops for loading, unloading, and stacking palletized goods.
Common types of electric stackers
1. Pallet Type Electric Stacker
This common and affordable stacker has legs at the front and is simple to use.
2. Wide Leg Electric Stacker
The front legs of this stacker are wider, typically between 550/680mm, but can extend up to 1200/1500mm to handle double-sided pallets (as long as the pallet length fits within the width). It’s moderately priced and can deal with double-sided pallets or certain special goods.
3. Counterbalance Electric Stacker
This stacker doesn’t have legs at the front; instead, it has a counterweight at the back. The forks can tilt forward and backward to keep the load level. It’s versatile, similar to traditional combustion engine forklifts, but it’s longer and requires wider aisles. It’s also more expensive.
4. Reach Electric Stacker
Similar to the counterbalance type but without front legs and with a counterweight. The difference is that the forks and mast can move forwards and backwards, usually by about 560mm, which can help to shorten the length of the stacker for tighter aisles. The price is similar to the counterbalance stacker.
5. Stainless Steel Electric Stacker
Made entirely of stainless steel, this stacker is for environments where cleanliness is crucial, like food and pharmaceuticals. It’s slightly more expensive.
6. Explosion-Proof Electric Stacker
A specialized model that meets strict production and safety standards for high-risk environments. It has explosion-proof ratings, is technologically advanced, and is quite expensive.
7. Single Mast Electric Stacker
This stacker has a single pole for lifting instead of the traditional dual mast, allowing for faster, more stable, and even lifting. The lifting mechanism often uses a belt instead of chains, which ensures a smoother lift.
How to operate an electric stacker?
Electric forklifts are a specialized equipment used to lift and load/unload goods. The operation method is as follows:
Step 1: Inspect the forklift
- Check if the forklift’s battery power is sufficient. If not, charge it beforehand.
- Check the condition of the forklift’s tires to ensure stable and safe driving.
- Check that the hydraulic system, braking system, and steering wheel of the forklift are functioning properly.
Step 2: Prepare the work
- Wear the necessary personal protective equipment, such as a safety helmet and safety shoes.
- Ensure that the work area of the forklift is free of obstacles and that there are no people nearby.
- Confirm the weight and size of the goods in order to properly adjust the height and angle of the forklift.
Step 3: Operate the forklift
- Select a suitable entry point based on the size of the forklift and the seat height, to get into the operator’s position.
- Locate the forklift’s key and insert it into the ignition switch to turn on the power.
- Adjust the seat and pedal positions to ensure a comfortable and stable foot position.
- Fasten the seatbelt to ensure safe driving.
Step 4: Operate the controls
- Familiarize yourself with the forklift’s controllers, understanding the functions of each button and indicator light.
- Use the lift and lower buttons on the controller to control the raising and lowering of the load.
- Use the forward and reverse buttons on the controller to control the movement of the forklift.
- Use the left and right turn buttons on the controller to control the steering of the forklift.
- Adjust the height and angle of the control console to facilitate observation of the load and work area.
Step 5: Loading and unloading the cargo
- Use the lifting function of the forklift to raise the cargo to a suitable height, and then move it to the target location.
- When moving the cargo, maintain a slow and steady speed to avoid collisions or tilting.
- While operating the forklift, pay attention to the surrounding environment and avoid colliding with other personnel or equipment.
- When safely placing the cargo, use the lifting function of the forklift to slowly lower the cargo to the desired location.
Step 6: Shutdown operations
- Before the operator leaves the forklift, they should first unload the cargo and park the forklift in a safe and stable location.
- Turn off the forklift’s ignition switch to stop the power supply.
- Check that the forklift’s hydraulic system, braking system, and other components are functioning normally to ensure the forklift is in a reliable state.
Summarize
When operating an electric forklift, the operator needs to have relevant operating skills and safety awareness. The correct operating method can improve work efficiency and reduce operational risks. At the same time, regular maintenance and inspection of the forklift equipment is the key to ensuring its normal operation, guaranteeing the safety of the operator and the cargo.
