OPD Series Low Level Order Picker

Smart Lifting, Easy Moving — LI-UNILIFT

Efficient order picking in distribution centers and retail warehouses requires specialised low-level picking equipment built for continuous cycle work. The OPD20/25-581(UGD) low level order picker supports 2000kg and 2500kg load variants, with a unique guide-raise lifting system that avoids hoisting the entire battery pack during operation. This seated picking machine is optimised for high-frequency order retrieval along long rack aisles.

Energy-Saving Lifting Architecture For Extended Shift Work

A patented guide-raise lifting mechanism is fitted to this OPD order picker. Only the forks and cargo are raised during picking tasks, while the heavy battery stays stationary on the chassis. Less energy is consumed with each lift cycle, which stretches run time between charging sessions for multi-shift warehouse sites.

Side-mounted battery placement is adopted as the standard layout. Batteries can be accessed and swapped quickly, minimising downtime during busy picking schedules. Operators are spared from complicated disassembly work, and fleet managers gain greater flexibility to keep picking workflows running nonstop.

Intuitive Operator Controls For Smooth Order Retrieval

A centered return-to-neutral design is built into the steering handle. After each steering adjustment, the handle automatically returns to its resting position, which helps operators maintain consistent control during long picking routes. Jogging control points are arranged on both sides of the vehicle body, so responsive speed adjustments can be made from different working postures.

Electronic power steering delivers light, quiet steering feedback throughout every aisle turn. Physical strain is reduced during extended picking shifts, especially in facilities with hundreds of pick stops each day. An AC drive motor without carbon brushes is used, cutting routine maintenance tasks such as brush inspection and replacement.

Active Safety Features For High-Speed Aisle Operation

Curve automatic deceleration is integrated into the vehicle control logic. Travel speed is reduced automatically once a turn is detected, so cargo stability is preserved and collision risks are lowered in narrow racking aisles. The QEXPEND AC controller governs stepless speed regulation and holds multiple built-in protective functions against electrical overload and abnormal operating conditions.

Electromagnetic braking is deployed for reliable stopping performance. The braking system responds predictably at different travel speeds, supporting safe stops when operators encounter unexpected obstacles while picking goods.

• Unique guide-raise lifting design saves energy by lifting only loads instead of the full battery assembly
• Side-mounted battery layout enables convenient battery exchange and quick power restoration
• Centered self-return steering handle paired with dual-side jogging controls for flexible operation
• Brushless AC drive motor eliminates carbon brush wear and lowers routine maintenance demands
• Lightweight electronic steering cuts operator fatigue during long continuous picking rounds
• Curve automatic deceleration stabilises the truck when navigating corners in rack aisles
• Multi-protection QEXPEND AC controller provides stepless speed adjustment and fault monitoring
• Electromagnetic braking system delivers consistent, dependable stopping power in busy warehouses

Refining Low-Level Order Picker Performance For E-Commerce Fulfillment

Fulfillment centres are constantly seeking order picking solutions that raise throughput while keeping operating costs in check. Low-level order pickers are relied on heavily for fast batch picking, and energy efficiency alongside operator comfort have become core evaluation criteria. LI-UNILIFT refines the OPD series low level order picker to address these modern fulfilment challenges.

Engineers tune the lifting energy consumption curve and calibrate steering and deceleration parameters for long aisle travel. Ergonomic layout of controls, low-noise powertrain operation and robust chassis durability remain core design priorities. Ongoing field validation is performed for both lead-acid and optional lithium battery configurations to suit varied fulfilment centre schedules.
