Electric Stacker – New Version Professional Material Handling Equipment

Electric Stacker – New Version Professional Material Handling Equipment

Designed for high-intensity warehousing and industrial environments, the new-generation electric stacker integrates advanced manufacturing techniques with operator-centric engineering. This model features a one-piece fork arm constructed with 90mm thickened reinforced steel, fully automated seamless welding technology, and a SEGA intelligent control system. The unit delivers a rated load capacity of 1500kg, maximum lift height of 3500mm, and a compact turning radius of 1450mm, making it suitable for narrow aisle operations. Power is supplied by a 24V/210Ah lithium battery pack, ensuring 8–10 hours of continuous operation under full load. The stacker is equipped with wear-resistant polyurethane silent wheels, compatible with epoxy and various industrial floor surfaces, significantly reducing rolling resistance and operational noise levels.

Structural Integrity and Frame Design

The stacker adopts a monolithic mast and chassis integration, eliminating bolted joints in critical load-bearing sections. This design enhances torsional rigidity and distributes stress evenly across the frame. The overhead guard is constructed from high-tensile steel plate with a thickness of 5mm, meeting ISO 6055 impact protection standards. All welded joints are produced via robotic gas-shielded automatic welding, achieving consistent penetration depth and a smooth, uniform bead profile without spatter or undercut defects. This process ensures structural reliability even after prolonged heavy-duty cycles.

One-Piece Fork Arm Engineering

The fork arm is fabricated from a single piece of 90mm thick high-carbon steel, hot-rolled and precision-machined to eliminate seams between the blade and the shank. This seamless integration prevents debris accumulation and reduces stress concentration points that typically lead to metal fatigue in sectional designs. The fork surface is induction-hardened to 45–48 HRC, providing superior abrasion resistance against pallet wear. With an effective fork length of 1150mm and adjustable width range of 200–685mm, the unit accommodates standard European and American pallet dimensions without auxiliary attachments.

SEGA Intelligent Control and Ergonomic Handle

The proprietary SEGA electronic system integrates proportional valve control, regenerative braking, and load-sensing hydraulics within a sealed IP54-rated controller housing. The tiller handle is ergonomically contoured with a die-cast aluminum grip, featuring a butterfly-type thumb-operated accelerator switch that provides proportional speed modulation from 0 to 6.0 km/h. The handle incorporates a dual-twist reversing mechanism and an integrated emergency reverse bumper, ensuring immediate directional changes upon contact with the operator. The control interface includes a digital display panel showing real-time battery status, hour meter, and fault diagnostics.

Hydraulic and Lifting Performance

The lifting system utilizes a double-acting hydraulic cylinder with chromed piston rod, supported by a gear pump driven by a 3.0kW AC induction motor. Maximum lifting speed reaches 0.12 m/s unloaded and 0.09 m/s at full rated capacity, with lowering speed adjustable via proportional valve from 0.05 to 0.15 m/s. The system incorporates an overload protection valve set at 110% of rated pressure, preventing operation beyond safe working limits. A manual descent emergency valve is provided for power failure scenarios, enabling controlled lowering without electrical input.

Wheel Configuration and Floor Compatibility

The stacker is equipped with polyurethane load wheels and a central drive wheel, all manufactured from high-durometer non-marking compounds. These wheels deliver a Shore A hardness of 93±2, balancing load-bearing capacity with floor protection. The polyurethane material exhibits low rolling resistance coefficients of 0.035 on epoxy surfaces and 0.042 on concrete, translating to extended battery life per charge cycle. The solid construction eliminates pneumatic puncture risks and reduces maintenance intervals, while the tread pattern is engineered for self-cleaning properties in dusty warehouse conditions.

Welding Quality and Surface Finish

All structural joints are processed using computer-controlled pulsed MIG welding with 100% argon shielding gas. The welding parameters are monitored in real-time, maintaining heat input within ±2% tolerance to prevent metallurgical degradation in the heat-affected zone. Post-weld grinding produces a smooth, ripple-free finish with a surface roughness of Ra ≤ 3.2μm. Each unit undergoes magnetic particle inspection to verify zero porosity or microfractures in critical load paths.

Polyurethane Wheel Performance Characteristics

The polyurethane compound is formulated with internally lubricated additives that reduce surface friction without leaving marks on epoxy, polished concrete, or PVC flooring. The wheel core is reinforced with glass-fiber infused nylon, providing impact resistance while maintaining lightweight properties. Static load capacity per wheel is rated at 800kg, with dynamic shock absorption capable of handling intermittent loads up to 120% of nominal rating. The solid tire profile ensures consistent rolling performance across temperature ranges from -10°C to +45°C.

Operational Safety and Control Logic

The butterfly-type accelerator incorporates a two-step safety interlock: initial contact activates the power assist without drive engagement, while progressive thumb pressure modulates torque output through the MOSFET-controlled motor driver. Release of the accelerator triggers dynamic braking with regeneration, recovering up to 12% of kinetic energy during deceleration. The handle-mounted horn and battery discharge indicator are positioned within natural thumb reach, minimizing hand movement during repetitive stacking operations. An automatic speed reduction function limits travel speed when the forks exceed 500mm lift height, maintaining stability during elevated load handling.
