CBD Series Multi‑Configuration 3500‑Capacity Electric Pallet Truck

Smart Lifting, Easy Moving — LI‑UNILIFT

High‑volume distribution centres require flexible 3500 kg pallet‑handling solutions that can adapt to double‑pallet long‑fork, single‑pallet stand‑on and walkie working scenarios. The CBD35‑510/520/530 electric pallet truck family shares patented floating drive‑unit, electronic power steering and curve auto‑deceleration safety logic, while offering distinct chassis layouts to match diverse warehouse throughput requirements.

Shock‑Absorbing AC Powertrain Across Three Platform Variants

Every unit within the CBD35 series is equipped with patent‑protected floating drive‑unit mechanism. This mechanical assembly absorbs impacts from imperfect concrete flooring, which isolates vibration away from motor, controller and wheel groups to reduce component fatigue amid heavy‑load transport cycles.

Brushless AC drive hardware forms the core propulsion system. Carbon‑brush related wear points are eliminated, which cuts recurring inspection and part‑replacement work for fleet operators. Electronic power‑assisted steering delivers light‑weight, low‑noise directional control; operators complete frequent turning movements with minimal physical strain even during extended multi‑shift assignments.

The proven ZAPI AC controller delivers stepless speed modulation together with multi‑layer automatic protection mechanisms against overload, overheating and unexpected electrical faults. Electric lifting delivers rapid and responsive fork travel, while factory‑fitted lifting limit switch prevents hydraulic over‑travel to safeguard lifting assemblies and conserve battery energy. Electromagnetic‑regenerative composite braking recycles kinetic energy in deceleration phases and supplies dependable stopping force under both laden and unladen conditions.

Bilateral side‑pull battery structure comes as standard specification. Battery packs can be slid out from either side of the truck, so battery swap‑out work is completed without large‑scale housing disassembly. Standard 24V‑360Ah battery supports long runtime, and FAAM 330Ah or 490Ah battery options are available to adjust energy reserves for different shift intensities. Heavy‑duty PU wheel assemblies maintain consistent rolling performance on typical warehouse floor surfaces.

Variant‑Specific Layouts With Active Corner‑Safety Logic

Transitioning between different material‑handling workflows is simplified by three tailored configurations within the CBD35 product range, each optimised for unique pallet‑handling missions.

Curve automatic deceleration safety logic is implemented on all three models. When the truck enters turning manoeuvres, travel velocity is intelligently reduced, which suppresses cargo sway and lowers potential tipping hazards when transporting full‑weight 3500 kg payloads. A built‑in load backrest is supplied as standard; this backrest prevents cargo from sliding backward during transit and improves load stability for stacked pallet goods.

CBD35‑510 is the double‑pallet stand‑on variant. Its extra‑long fork design handles two pallets in one pass, greatly raising throughput for cross‑zone bulk‑goods transfer. Higher‑output 4.2 kW AC traction motor is fitted to match the heavier combined payload. Owing to its extended wheelbase and overall length, it is best deployed in spacious distribution zones rather than compact rack aisles.

CBD35‑520 adopts single‑pallet stand‑on architecture. It retains stand‑on riding comfort while shortening overall chassis dimensions, striking a middle ground between transport efficiency and aisle‑space compatibility. The 1.5 kW AC drive motor is well‑matched for regular single‑pallet heavy‑duty handling tasks.

CBD35‑530 is built as walkie‑only pedestrian‑operated version. It removes the stand‑on operator station to achieve the most compact footprint of this product family. This configuration fits facilities where operators prefer walking alongside the truck, especially for tight rack‑aisle stacking and retrieval jobs.

Multiple fork specifications are selectable. Users can opt for double‑pallet long forks or conventional single‑pallet fork sets according to daily pallet‑handling patterns. Travel, lifting and lowering parameters for each variant are fine‑tuned to create sensible balance between handling throughput and onsite safety compliance.

Broad‑Scope Heavy‑Duty Intralogistics Deployment

With uniform 3500 kg rated load capacity across the lineup, the CBD35 series covers multiple heavy‑load intralogistics use‑cases. These scenarios include large‑scale manufacturing plants, high‑throughput wholesale distribution hubs, e‑commerce mega‑fulfilment depots and cross‑dock freight terminals.

Thanks to three distinct chassis options, warehouse teams can select the most suitable variant for their site layout. Double‑pallet 510 model accelerates bulk goods movement in open wide‑aisle yards; single‑pallet stand‑on 520 balances speed and spatial adaptability; walkie‑type 530 serves compact rack‑heavy storage zones. In addition, optional FAAM high‑capacity battery packs extend available runtime for round‑the‑clock multi‑shift operations. Standard side‑dual‑pull battery design makes spare‑battery rotation straightforward for non‑stop workflows.

Unified Modular Design Streamlines Fleet‑Wide Servicing

LI‑UNILIFT embeds service‑orientated engineering philosophy into the whole CBD35 product family. Shared core assemblies including floating drive‑unit, ZAPI controller, side‑pull battery system and brushless AC powertrain simplify spare‑parts inventory and on‑site troubleshooting work for maintenance teams managing mixed‑variant fleets.

• Patent floating drive‑unit dampens floor‑sourced shocks and extends service life for key powertrain components
• Bilateral side‑pull battery design enables convenient battery removal from either truck side
• Brush‑free AC traction motor eliminates periodic carbon‑brush inspection and replacement cycles
• Trusted ZAPI AC controller supports built‑in diagnostic routines to speed fault localisation
• Standard load backrest enhances cargo stability during heavy‑payload transit
• Interchangeable fork options support switching between double‑pallet and single‑pallet working modes

Advancing Modular Multi‑Variant Heavy‑Capacity Pallet Truck Development

Modern large‑scale intralogistics increasingly demands one product platform with multiple mechanical variants, so fleets can match equipment precisely to aisle dimensions and pallet‑batch patterns. LI‑UNILIFT keeps carrying out practical technical refinements for high‑capacity modular AC‑driven pallet‑truck platforms. These development directions cover floating drive‑unit shock‑absorption optimisation, curve‑automatic‑deceleration safety‑logic iteration, dual‑side battery‑access mechanical refinement and cross‑variant common‑part standardisation.

Beyond powertrain and mechanical‑system improvements, human‑centred ergonomics, multi‑layer active‑safety safeguards and rigid heavy‑duty chassis construction remain core engineering priorities. The R&D team continues exploring forward‑looking possibilities, including load‑responsive speed adjustment and unified fleet‑condition monitoring for mixed‑configuration warehouse equipment pools.
