LiuGong has been leading the charge toward a greener future with their Green Machine heavy‑duty alternatives. These electric machines are already a staple in mining, construction, agriculture, port and logistics across Africa, and now LiuGong has introduced the LRSE4531E E‑Series Reach Stacker.

This new model is designed for energy efficiency and helping operations run smoothly while cutting fuel costs and boosting productivity. LiuGong’s National Laboratory has refined the structural components to ensure strength and durability under extreme working conditions.

Equipped with independently controlled hydraulic and drive motors, the LRSE4531E offers precise control, improved safety, and greater efficiency. Its powerful permanent magnet synchronous motors deliver high torque, fast response, and excellent energy savings, while CATL high‑capacity lithium iron phosphate batteries provide reliability and a long service life.

An intelligent thermal management system ensures performance in both high and low temperatures. Motors, controllers, and batteries are cooled during heat, while the lithium battery features automatic heating in cold conditions. Steering axle deviation has been reduced by 90%, improving stability and extending tire life.

Safety and reliability

 The LRSE4531E is equipped with advanced safety systems to protect operators, cargo, and bystanders:

  • Safety active system: Detects staff or objects in the alarm zone and automatically applies the brake.
  • Automatic fire suppression: Sensors around the battery detect heat or smoke, triggering alarms and extinguishing systems.
  • High‑voltage interlock: Prevents activation until the circuit is fully connected and safe.
  • Insulation detection: Cuts off power if electrical leakages are detected.
  • Ground protection: Ensures the battery’s ground is bonded to the frame, reducing electric shock risk.
  • Roller Protect system: Multi‑level protection to prevent roller damage and ensure safe container lifting.
    • Level 1: Text alarm
    • Level 2: Text + sound alarm
    • Level 3: Lift/down lockout, released via manual bypass valve
    • Container sit protection: The container cannot lift, unless all four pin locks are closed

The system is also self‑diagnosing, automatically displaying error codes when faults occur.

Smart and efficient

 The LRSE4531E features a clear intelligent display system with 360° video, machine status indicators, and mobile app connectivity for convenient management.

Vertical lift technology: Calculates container angle and weight to optimise boom extension and lifting efficiency.

Self‑adjust damping: Quickly levels the spreader when handling empty containers and reduces sway when loaded.

Electrical control hydraulic system: Responds quickly to adjust output, saving energy.

Direct motor drive: Connects the motor directly to the drive axle and hydraulic pump, improving efficiency by 10%.

Energy conservation

 This electric reach stacker delivers zero emissions and regenerates braking energy, achieving up to 70% energy savings compared to internal combustion models. Over five years, this translates into significantly lower operating costs.

Its hydraulic defoaming technology removes air bubbles from hydraulic oil, extending replacement intervals by 1,5 times and reducing maintenance costs.

Comfort and convenience

 Operator comfort is built into the design:

  • Patented electric sliding cab powered by a 24V motor, operable from inside or outside.
  • Inside the cab: wide visibility, low noise, air conditioning, adjustable seat angle, and movable operator arm.
  • Exterior features: front, rear, boom, and spreader lights.
  • Easy maintenance: core components like motors and batteries are accessible, and the radiator fan can reverse to clear dust.

Mature and reliable

Like all LiuGong machines, the LRSE4531E uses trusted international components from partners with over 30 years of collaboration.

It can accommodate:

  • 40 ft container spreader
  • 20 ft tilting spreader
  • Steel pipe spreader
  • Lumber clamp
  • Slab magnet
  • Rolling‑over attachment

With a rated capacity of 45 000 kg, drive motor power of 157/310 kW, maximum boom height of 15 100 mm, and 60° boom tilt, the LRSE4531E can stack up to five layers. The spreader also offers a lateral movement distance of about 800 mm.

The LiuGong LRSE4531E E‑Series Reach Stacker represents the future of heavy‑duty handling, combining strength, safety, and sustainability in one machine. With its advanced technology, zero‑emission performance, and operator‑focused design, it delivers unmatched efficiency while lowering costs and protecting the environment. Built for Africa’s toughest industries, this reach stacker is proof that innovation and reliability can go hand in hand.
