What design does the Electric Middle Level Order Picker use to improve stability?

The Electric Middle Level Order Picker adopts an innovative low-center-of-gravity architecture design. By scientifically arranging the large-capacity battery pack at the bottom of the vehicle body, the center of gravity height of the vehicle is significantly reduced. At the same time, the core components such as the drive motor and the transmission shaft adopt a compact integrated layout solution to avoid the problem of high center of gravity caused by the upper power system in the traditional design.

The main body of the frame is welded and formed with high-strength alloy steel as a whole. After finite element analysis and optimization of the structure, it achieves a lightweight design while ensuring strength. The key stress-bearing parts are specially thickened to give the frame excellent anti-bending and anti-torsion properties. The door frame adopts a box-section design with a reinforcing rib structure inside to ensure that it will not deform during high-load lifting. The unique modular design allows the frame and the door frame to be quickly separated and interchanged. All connection parts use high-precision machined mating surfaces with high-strength fasteners, which is not only easy to maintain, but also ensures that there will be no loosening during long-term use.

The steering system adopts advanced electric power assist technology, equipped with intelligent angle sensors and control systems, which can automatically adjust the steering assist according to the vehicle speed. The automatic return function detects the steering angle through precise sensors, and automatically returns the wheel to the correct position after the steering operation is completed, effectively avoiding the common deviation problem of traditional vehicles after steering. The lifting control system adopts a closed-loop control algorithm. When the fork drops to 500mm from the ground, it automatically switches to the slow-down mode. By adjusting the opening of the hydraulic valve, the descent speed is steadily reduced, which not only reduces the impact noise, but also effectively prevents the goods from shifting or dumping due to sudden deceleration.

The hydraulic system is equipped with a high-performance accumulator, which can absorb oil pressure pulsation, keep the system pressure stable, and avoid the pressure fluctuation during the lifting process causing the goods to shake. The explosion-proof valve adopts a double protection design. When the system pressure exceeds the safety threshold, it will immediately cut off the oil circuit to prevent the pipeline from bursting. The triple lifting limit protection system includes: the electronic limit monitors the fork position in real time through the height sensor; the hydraulic limit cuts off the oil circuit when the set height is reached; the mechanical limit is the last guarantee, and the lifting height is physically limited by the hard block. This multiple protection mechanism ensures that no over-high lifting accidents will occur under any circumstances.
