Product Description
Fully Hydraulic Tyre Cranes utilize hydraulic transmission for lifting, boom adjustment, slewing, and traveling functions. Their pilot-controlled proportional system enables coordinated lifting, boom adjustment, and slewing operations. As mobile lifting equipment that integrates traveling and hoisting capabilities, these cranes employ a fully hydraulic drive system, delivering high mobility and operational efficiency. They are widely used in construction, port operations, logistics, and related fields, demonstrating exceptional versatility and productivity.
1. Basic Structure and Composition
Chassis Part:
Tire walking mechanism: Adopts a multi-axis tire chassis, providing road driving capability, a small turning radius, and the ability to transfer sites without towing.
Drive system: Fully hydraulic drive, including a hydraulic motor, gearbox, and drive axle, enabling stepless speed change.
On-board Part (Lifting Mechanism):
Hydraulic system: Composed of a hydraulic pump, control valve, and actuator (hydraulic cylinder, motor), it facilitates lifting, boom adjustment, rotation, and other actions.
Lifting arm: Typically a telescopic box structure; some models are equipped with a truss auxiliary arm to expand the working range.
Turntable: Supports the lifting arm and control room, allowing 360° full rotation.
Weight: Features a detachable design to balance the overturning moment during lifting.
2. Core Features
Full Hydraulic Control:
All movements (lifting, boom adjustment, rotation, support leg extension and retraction) are completed by the hydraulic system, ensuring stable and precise operation.
Uses a load-sensitive pump or electro-hydraulic proportional valve to achieve intelligent matching of flow and pressure, improving energy efficiency.
Strong Mobility:
The tire design is suitable for short-distance transfers, with road speeds reaching 30–80 km/h.
Some models feature all-wheel steering or crab walking mode, making them suitable for narrow sites.
Safety Devices:
Force limiter, overload protection, level indicator, and support leg pressure sensor ensure operational safety.
Equipped with an emergency hydraulic system to prevent loss of control in case of sudden failure.
3. Main Technical Parameters
- Lifting capacity: Ranges from 10 to 300 tons, with small and medium-sized models (25–50 tons) being the most widely used.
- Working radius: The main arm can extend up to 30–60 meters, with the auxiliary arm further expanding the range.
- Power configuration: Diesel engine (China VI/EU VI emission standards) or hybrid (electric + diesel).
- Leg type: H-type or X-type hydraulic legs to improve operational stability.
