Driver’s cab lifting device – genuine HOWO complete electro‑hydraulic cab tilt system kit for MAX 4X2
This Driver’s cab lifting device kit includes every component from the motor and pump to the cylinder, oil pipes, brackets, fasteners, and hydraulic oil. No additional parts are required for a full cab tilt system replacement.
The manual hydraulic pump with electric motor offers both manual and automatic operation, ensuring the Driver’s cab lifting device remains functional even in the event of electrical failure – a critical safety feature for roadside repairs.
The Driver’s cab lifting device is supplied with genuine No.10 aviation hydraulic oil, which provides optimal lubrication and corrosion protection, ensuring smooth and reliable cab tilting even in extreme temperatures.
All bolts in this Driver’s cab lifting device are supplied with serrated flanges, spring washers, or self‑locking nuts to prevent loosening under severe vibration, ensuring the cab remains securely latched during driving.
The Driver’s cab lifting device uses a 24V electric motor to drive a hydraulic pump, which pressurises the No.10 aviation hydraulic oil and sends it through the oil pipes to the lifting cylinder. The cylinder extends, pushing the cab forward and upward to provide access to the engine compartment.
A manual hand pump is also integrated, allowing operation without electrical power. The system includes a pressure relief valve to prevent over‑pressurisation, and check valves to lock the cab in the raised position. Lowering the cab is achieved by releasing the control valve,
allowing oil to flow back to the reservoir under gravity. The entire Driver’s cab lifting device is designed to tilt the cab to a maximum angle of 45° with a lifting capacity of 5 tonnes. Regular lubrication of the pivot pins and inspection of the oil pipes are essential for maintaining smooth operation.
Before installation, ensure the vehicle is on level ground and the cab is in its fully lowered position. Remove the old Driver’s cab lifting device components. Clean all mounting surfaces. Install the right fixing bracket and lower holder of the turnover cylinder using the M16 bolts and toothed nuts (torque to 180 Nm).
Attach the motor assembly and pump using the M10 bolts and nuts (torque to 40 Nm). Connect the lifting cylinder using the lifting pin shaft and secure with the M14 nut (torque to 120 Nm). Install the oil pipes, ensuring all connections are tight. Route the hoses away from moving parts and secure them with the plastic fastening belts.
Fill the reservoir with No.10 aviation hydraulic oil. Connect the electrical wiring to the switch bracket. Bleed the system by manually pumping the hand pump to remove air. Test the Driver’s cab lifting device by raising and lowering the cab several times. Check for leaks and re‑tighten any loose connections. The installation is now complete.
If the cab does not raise, check the hydraulic oil level and the electrical supply to the motor. A low oil level will prevent the pump from generating sufficient pressure. If the motor runs but the cab does not move,
the pump may be cavitating or the oil pipes may be blocked. Inspect the oil pipes for kinks or leaks. If the cab lowers slowly, the check valve may be leaking or the piston seals in the cylinder may be worn.
A noisy pump often indicates air in the system; bleed the Driver’s cab lifting device by cycling the pump with the reservoir cap loose. Loose bolts or brackets can cause rattling; retorque all fasteners. Always use genuine components for repair to ensure compatibility and safety.
Inspect the Driver’s cab lifting device every 50,000 km or annually. Check the hydraulic oil level and top up if necessary.
Inspect the oil pipes for chafing or cracking. Lubricate the pivot pins and the lifting cylinder rod with a light grease. Test the system by raising and lowering the cab to ensure smooth operation. Replace the hydraulic oil every two years or 200,000 km.
Check all bolts for tightness – retorque the M16 bolts to 180 Nm, M14 to 120 Nm, and M10 to 40 Nm. Keep the motor and pump clean and free from debris. A well‑maintained Driver’s cab lifting device ensures safe and easy cab tilting for many years.

The M16, M14, and M10 bolt sizes correspond to the original SINOTRUK specifications. This Driver’s cab lifting device is not compatible with older A7 or WD615 models, which use different cylinder mountings and pump configurations. Always verify your vehicle’s chassis number and cab type before ordering.
Aftermarket Driver’s cab lifting device components often use inferior seals and lower‑grade steel that can fail under pressure, leading to sudden cab collapse and serious injury. Generic hydraulic oil may not provide adequate lubrication, leading to premature pump failure. Non‑genuine fasteners can loosen, causing misalignment and damage to the cab structure.
A failed Driver’s cab lifting device can trap the cab in the raised position, preventing access to the engine and potentially causing delays in emergency repairs. Genuine HOWO components are manufactured to SINOTRUK’s exacting standards,
using certified materials, precision‑machined cylinders, and high‑quality seals. The small additional cost of a genuine Driver’s cab lifting device is insignificant compared to the safety of the driver and the reliability of the vehicle.
