4–5 Ton G Series Diesel Counterbalance Forklift
The G Series is a range of heavy-duty diesel counterbalance forklifts designed for businesses that need reliable performance when handling medium to heavy loads.
The 4–5 ton range includes:
CPCD-G40 – 4,000 kg
CPCD-G45 – 4,500 kg
CPCD-G50 – 5,000 kg
With a 500 mm load center, 3,000 mm standard maximum lifting height and rugged counterbalance construction, these forklifts are suitable for demanding industrial material handling applications.
Strong Diesel Power
The G Series is equipped with reliable diesel powertrains designed to provide sufficient power for lifting, traveling and transporting heavy loads.
The CPCD-G40 uses a Quanchai V23-52V42 engine with:
Rated power: 36.8 kW / 2500 r/min
Maximum torque: 170 N·m / 1800 r/min
Number of cylinders: 4
Displacement: 2.85 L
The CPCD-G45 and G50 use a Quanchai V35-C43 engine with:
Rated power: 48 kW / 2200 r/min
Maximum torque: 240 N·m / 1600 r/min
Number of cylinders: 4
Displacement: 3.67 L
The diesel powertrain provides strong traction and reliable performance for heavy-duty material handling.
Stable Counterbalance Structure
The G Series adopts a counterbalance forklift design, allowing the machine to maintain stability when lifting and transporting heavy loads.
The CPCD-G40, G45 and G50 models feature a 500 mm load center.
The wider chassis and optimized weight distribution provide a stable operating platform for loading, unloading, transportation and stacking.
Side Rollers for High-Level Stability
Side rollers are installed above the main rollers.
When the forks are raised and the mast sections overlap, the side rollers help reduce lateral movement of the mast and forks.
This improves stability during elevated lifting operations and allows operators to position loads more accurately during stacking.
Wide-Visibility Mast
The mast structure has been optimized to provide a wider forward field of view.
The mast uses C-section steel, providing good bending characteristics and structural strength.
The improved visibility helps operators observe the forks and load more easily, particularly during loading, unloading and stacking operations.
Reliable Hydraulic System
The hydraulic system is designed to provide precise lifting, lowering and tilting control.
The hydraulic lines use 24° cone sealing, helping reduce the possibility of hydraulic leakage.
Hydraulic oil is filtered twice before flowing to the actuators, improving oil cleanliness and helping protect hydraulic components during long-term operation.
The improved filtration design can help extend the service life of hydraulic components.
Ergonomic Steering Wheel
The G Series uses a compact 320 mm diameter steering wheel designed according to ergonomic principles.
The steering angle can be adjusted to provide a more comfortable operating position.
The smaller steering wheel provides good handling feedback while helping reduce operator fatigue during extended operation.
Digital Instrument Panel
The digital instrument panel uses CAN bus communication technology to provide clear operating information.
The human-machine interface allows the operator to monitor the forklift's operating condition in real time.
The system can provide:
Operating status information
Fault alarms
Diagnostic information
System monitoring
This makes daily operation and troubleshooting more convenient.
Intelligent Operator Controls
The integrated control system is designed according to ergonomic principles.
The operating handle and electrical switches are arranged for convenient access and intuitive operation.
A standard USB fast-charging interface provides additional convenience for operators during long working shifts.
Spacious Operator Compartment
The operator area has been optimized to provide more legroom while reducing the height of the entry step.
The combination of:
Anti-slip step
Wide spring-assisted handrail
Increased legroom
Lower entry height
makes entering and exiting the forklift more convenient and improves operator comfort during daily operation.
Durable Stamped Engine Hood
The stamped engine hood provides a solid and durable structure.
The hood has a large opening angle, providing convenient access to the engine compartment and internal components.
Daily inspection and maintenance can therefore be completed more efficiently.
Centralized Electrical System
Electrical components such as fuses and relays are centrally arranged inside the electrical box.
The electrical box is equipped with sealing protection to help reduce the influence of dust and moisture.
The centralized design makes electrical inspection, troubleshooting and maintenance more convenient.
Two-Stage Air Filtration
The diesel engine uses a two-stage air filtration system consisting of:
Paper Air Filter + Air Pre-filter
The two-stage design provides more effective intake-air filtration and helps protect the engine when operating in dusty environments.
This is particularly useful for construction sites, outdoor yards and industrial applications where airborne dust may be present.
H-Type Electrical Wiring Layout
The electrical system adopts an H-type wiring layout.
Electrical components and wiring are arranged in an organized manner, making inspection and maintenance easier.
The flat wiring arrangement reduces unnecessary wiring and helps maintain a clean and serviceable electrical system.
Maintenance-Friendly Steering Axle
The G Series uses an integrated steering axle with tapered bearings for the kingpin assembly.
The design provides:
Strong impact resistance
Flexible steering
Stable travel
Improved vibration absorption
Reduced maintenance requirements
Selected bearing adjustment areas are designed for maintenance-free operation, helping reduce routine servicing requirements.
