The Stand-in Electric Stacker uses heavy and high-strength materials as a whole to ensure the durability of the vehicle body. Among the seemingly contradictory indicators of size, deadweight, maneuverability, and stability, the designer has achieved a better balance through careful calculations and multiple tests. Such a design not only ensures the maneuverability of the vehicle during driving and operation, but also ensures the stability of the vehicle body during operation, so that the vehicle has the obvious characteristics of a counterbalanced vehicle. The body design focuses on super rigidity, using high-strength steel and advanced welding technology to ensure that the vehicle can still maintain structural integrity and stability when bearing heavy loads. This design not only improves the safety of the vehicle, but also extends the service life of the vehicle.

The Stand-in Electric Stacker adopts a mid-floating drive design, which places the drive system in the middle of the vehicle, making the vehicle more stable during driving. At the same time, the design of the balance wheel support on both sides further enhances the stability of the vehicle, and can maintain good driving performance even on uneven roads.

In order to adapt to the load-bearing and operation requirements under different working conditions, the Stand-in Electric Stacker adopts a variable wheelbase structure design. The front axle can be moved to change the wheelbase length. When it is necessary to carry heavy objects or transport long distances, the wheelbase can be extended, which is equivalent to lengthening the body, so that it can carry goods more safely, tow better, and drive more smoothly. When it is necessary to work in a narrow environment, the wheelbase can be retracted, which is equivalent to shortening the body, improving maneuverability, reducing the required stacking channel, and being more convenient and flexible.

The Stand-in Electric Stacker is equipped with a new pedal, which is beautiful and comfortable to the foot. The shock absorber under the pedal can quickly absorb the vibration generated by the vehicle during operation and alleviate the impact caused by the road surface. This design not only improves the operator's comfort, but also reduces the impact of vibration on the stability of the base, ensuring the stability of the vehicle during driving and operation. When the stacker is transporting overweight goods, the buffer device on the gantry can effectively absorb the impact force generated by the inertia of the goods, prevent the goods from slipping, and also maintain the overall stability of the vehicle.

The protection arms are standard on both sides of the driver's seat. This design not only protects the operator's safety and prevents him from being injured by accidental collisions during operation, but also enhances the stability of the base structure to a certain extent. The protection arms are closely connected to the vehicle body to form a stable whole, which improves the vehicle's anti-rollover ability during driving and operation.

The emergency reverse switch installed on the control handle is an important safety auxiliary system for stand-up electric stackers. When the vehicle loses control when backing up, the operator's belly actively or passively touches the reverse switch, and the vehicle will immediately stop and quickly move in the opposite direction for a short distance to prevent the operator's body from being squeezed and injured. This design not only improves the safety of the vehicle, but also helps to maintain the stability of the vehicle in an emergency, indirectly enhancing the stability of the base.

The standard lifting electric limit function is another important safety auxiliary system for stand-up electric stackers. When the fork is raised to the top, the system automatically cuts off the upward power supply and stops smoothly, effectively preventing the occurrence of "top-falling" accidents. At the same time, this design can also reduce energy waste, extend the life of the hydraulic system and related components, ensure the stability of the vehicle during the lifting operation, and thus enhance the stability of the base.
