CBD Series Stand‑on High‑Speed AC‑Drive Electric Pallet Truck

Smart Lifting, Easy Moving — LI‑UNILIFT

Large‑scale distribution hubs require stand‑on pallet trucks that merge high‑speed transit, impact‑absorbing drive architecture and operator‑focused protective structures. The CBD20‑490 stand‑on electric pallet truck delivers 2000 kg rated load capacity. It is equipped with patented floating drive‑unit, 11 km/h top travel speed, electronic power steering and half‑enclosed operator cockpit, making it well‑suited for high‑cycle long‑distance material transfer inside expansive warehouse facilities.

Shock‑Dampening High‑Power AC Powertrain For Intensive Shifts

The CBD20‑490 is fitted with patent‑protected floating drive‑unit assembly. Since vibration originating from uneven concrete floors is buffered by this mechanical setup, stress transferred to motor, controller and wheel assemblies is greatly reduced during repeated heavy‑load transport cycles.

A 3 kW brushless AC traction motor is deployed as the core power source. Carbon‑brush‑related wear points are eliminated by this motor configuration, so regular brush inspection and replacement tasks are removed for fleet managers. Ample torque output is generated to support steep‑gradient travel, while maximum travel speed reaches 11 km/h to accelerate cross‑zone goods movement.

Electronic power‑assisted steering brings light‑touch, low‑noise directional control. Operators can complete frequent turning actions with minimal physical exertion, which eases fatigue accumulated over lengthy working periods. The trusted ZAPI AC controller delivers seamless stepless speed regulation; additionally, multi‑layer automatic protective mechanisms are embedded to defend the whole electrical system against overload, overheating and unexpected electrical faults.

Electric lifting delivers responsive fork movement, and a standard lifting limit switch is installed to prevent hydraulic over‑travel, which protects lifting components from overload damage and preserves battery energy. The 24V‑280Ah battery serves as standard power supply, while optional 320Ah large‑capacity battery and side‑pull 280Ah battery configurations are offered to satisfy varied multi‑shift operation demands. Heavy‑duty polyurethane wheel groups are utilised to maintain stable rolling performance on typical warehouse flooring.

Safety‑Centred Operator Environment With Intelligent Corner Handling

Beyond raw speed performance, multiple safety‑oriented features are integrated into the CBD20‑490 to mitigate risks during high‑speed warehouse transit.

A half‑enclosed cockpit surrounds the operator station. Physical buffer protection is provided against stray cargo and site obstacles, so operator security is elevated when the truck is running at high travel speeds. Curve automatic deceleration logic works in tandem with this protective structure. Whenever the truck enters turning manoeuvres, travel velocity is automatically lowered; consequently, cargo sway and potential tipping hazards are suppressed even under full‑load conditions.

Electromagnetic‑regenerative composite braking is adopted for this unit. Kinetic energy is recovered during deceleration events, and reliable stopping force is supplied regardless of laden or unladen operating states. Moreover, an optional 7 km/h low‑speed mode can be activated for congested zones with dense pedestrian activity. Multiple fork dimension choices are available to match mainstream global pallet specifications. Lifting and lowering speeds are carefully tuned, creating a balanced trade‑off between handling throughput and onsite safety compliance.

Customisable Power Options For Large‑Volume Intralogistics Assignments

With a 2000 kg maximum load rating, the CBD20‑490 fits a broad array of heavy‑duty logistics scenarios. These include large manufacturing plants, central distribution warehouses, high‑throughput e‑commerce fulfilment depots and busy cross‑dock freight terminals.

Different battery alternatives are provided to adapt to site‑specific operational requirements. The standard 280Ah battery can be swapped for side‑pull‑type 280Ah battery to simplify battery‑swap workflows for round‑the‑clock shifts. Users can also select the 320Ah high‑capacity battery variant for extended runtime, though this option cannot support side‑pull installation. The extra 7 km/h low‑speed profile is useful for mixed‑layout warehouses where fast transit and careful pedestrian‑heavy zone navigation are both required.

Modular Build To Simplify On‑Site Maintenance Work

LI‑UNILIFT incorporates practical service‑minded engineering across its complete material‑handling lineup, and the CBD20‑490 follows this design direction closely. Floating drive‑unit, brushless AC powertrain, proven ZAPI controller and interchangeable battery assemblies help service technicians finish inspection, fault localisation and component replacement efficiently.

• Patent floating drive‑unit absorbs floor‑sourced shocks and extends usable service life for key powertrain components
• Brush‑free 3 kW AC traction motor removes periodic carbon‑brush maintenance cycles
• Mature ZAPI AC controller carries built‑in diagnostic functions to shorten fault‑troubleshooting duration
• Multiple optional battery variants allow operators to prioritise either extended runtime or convenient side‑pull battery exchange

Advancing High‑Speed Stand‑on Pallet Truck Design For Large Warehouses

As modern intralogistics keeps pursuing higher throughput for expansive warehouse sites, greater emphasis is placed on shock‑resistant drive structures, active corner safety logic and flexible battery configurations for stand‑on pallet trucks. LI‑UNILIFT keeps carrying out practical technical refinements for high‑power AC‑driven stand‑on handling machinery. These optimisation efforts cover floating drive‑unit shock‑absorption tuning, curve‑automatic‑deceleration safety‑logic iteration and multi‑spec battery‑system compatibility expansion.

In addition to powertrain and mechanical refinements, human‑oriented ergonomics, multi‑layer active‑safety safeguards and sturdy protective cockpit construction remain central design priorities. The R&D team continues exploring forward‑looking possibilities, such as load‑sensitive speed limitation and fleet‑wide equipment health tracking for next‑generation mega‑warehouse operations.
