3. Working Principle

The tyre-type hydraulic crane operates through the coordinated work of five core systems: hydraulic power system, lifting mechanism, walking system, outrigger system, and electrical control system. Each system works in synergy to realize stable, precise, and safe lifting and walking operations, based on the principle of hydraulic pressure transmission and mechanical balance:

Hydraulic Power System: This is the core power source of the crane, consisting of a diesel engine (or electric motor), hydraulic pump, hydraulic cylinder, and hydraulic oil tank. The engine drives the hydraulic pump to convert mechanical energy into hydraulic energy, and the hydraulic oil is transmitted to each hydraulic component through pipelines to provide power for lifting, luffing, and walking. The hydraulic system adopts proportional control technology, ensuring smooth power output and precise operation. The rated pressure of the hydraulic system is usually 30-40 MPa, with a large flow rate to meet the needs of heavy-load operations.

Lifting Mechanism: Composed of a boom, wire rope, hoist, and hook. The hydraulic cylinder drives the boom to extend, retract, and luff, adjusting the working radius and lifting height. The hoist is driven by a hydraulic motor to wind or release the wire rope, realizing the lifting and lowering of loads. The boom is made of high-strength steel with a welded structure, which has high strength, rigidity, and resistance to deformation. The multi-section telescopic boom adopts a sequential telescopic cylinder to ensure stable and orderly extension.

Walking System: Composed of heavy-duty industrial tyres, drive axle, steering mechanism, and hydraulic motor. The hydraulic motor drives the drive axle to rotate, driving the tyres to move. The steering mechanism adopts hydraulic steering, supporting 360° in-place rotation and 90° right-angle steering, with a small turning radius, enabling flexible movement in narrow spaces. Heavy-duty off-road tyres (with or without inner tubes) are adopted to ensure stable movement and resistance to wear, suitable for various road conditions.

Outrigger System: Including telescopic outriggers and outrigger pads, which are used to support the entire crane during lifting operations, improving stability and preventing tipping. The outriggers can be extended horizontally and vertically to adjust the support range according to the site conditions. The large-span outriggers ensure that the crane can operate stably under heavy loads, and the outrigger pads increase the contact area with the ground to reduce ground pressure.

Electrical Control System: Coordinates the operation of the entire crane, including lifting, luffing, walking, and steering. It adopts PLC control technology, with complete safety protection devices, such as overload limiters, luffing limit switches, emergency stop buttons, and anti-collision devices. The control system has good waterproof and dustproof performance (IP55 protection level), adapting to harsh working environments. It can also realize real-time monitoring of the crane's working status, facilitating timely maintenance and troubleshooting.

Under the joint action of these systems, the tyre-type hydraulic crane completes the entire process of lifting, horizontal transfer, and accurate positioning of loads. Before delivery, each crane undergoes a static load test (1.25 times the rated load, hovering for 10 minutes) and a dynamic load test (1.1 times the rated load, composite lifting and running actions) to ensure 

that it meets safety and performance requirements.

4. Performance Advantages

Compared with traditional fixed cranes, crawler cranes, and other mobile lifting equipment, the tyre-type hydraulic crane has obvious advantages in mobility, stability, efficiency, and cost-effectiveness, making it the preferred choice for heavy-duty and medium-duty lifting scenarios. Its core advantages are as follows:

Superior Mobility & Fast Transfer: No need for fixed rail foundations or complex foundation construction, capable of moving freely on hardened roads, construction sites, and even slightly uneven ground. It has a fast travel speed (up to 30-80 km/h for road-going models) and can be quickly transferred between different work sites, reducing transfer time and improving work efficiency. The all-terrain type can adapt to off-road conditions, expanding the application scope.

Strong Lifting Capacity & Stable Operation: Adopting advanced hydraulic transmission technology and a high-strength boom structure, it has strong load-bearing capacity and stable lifting performance. The hydraulic system adopts proportional control and closed-loop servo control, ensuring smooth lifting and luffing, no impact during start-up and braking, and precise positioning of loads. The large-span outrigger system and anti-tilting device further improve operational stability, even under heavy loads and complex working conditions.

Flexible Operation & Wide Adaptability: The telescopic or foldable boom design allows flexible adjustment of the working radius and lifting height, adapting to different lifting needs. The 360° in-place rotation and small turning radius enable flexible operation in narrow spaces such as indoor workshops and narrow construction sites. It can work in a wide temperature range (-20℃～+40℃) and various harsh environments, with strong environmental adaptability.

Cost-Effective & Low Maintenance: The simplified structure and integrated hydraulic system reduce manufacturing and maintenance costs. It requires no complex foundation construction, and the installation and commissioning can be completed within 1-3 days. The key components are made of high-quality materials, with a low failure rate and a long service life. The maintenance is simple, with fewer maintenance points, reducing long-term operational costs. Compared with crawler cranes, it has lower ground damage and no need for track laying, further reducing use costs.

High Safety & Reliability: Equipped with complete safety protection devices, including overload limiters (automatically cut off power when overloaded), luffing limit switches, emergency stop buttons, anti-collision devices, and outrigger safety locks, effectively preventing safety accidents. The hydraulic system is equipped with a relief valve and a one-way valve to prevent oil leakage and ensure stable operation. The electrical components adopt internationally famous brands (such as Schneider, Siemens) with high reliability and long service life. The boom adopts non-destructive testing to ensure structural safety.

Customizable & Versatile: Can be customized according to customer needs, including load capacity, boom length, lifting height, and control mode. It can be equipped with various auxiliary tools, such as steel coil spreaders, container spreaders, and grabbing devices, to meet special lifting needs. It can be designed according to FEM, CMAA, EN ISO, and GB standards to adapt to global market requirements. The power system can be customized as diesel, electric, or hybrid according to the application scenario.

Energy-Efficient & Environmentally Friendly: The high-efficiency diesel engine or electric motor adopts energy-saving technology, reducing fuel consumption and emissions. The electric model has zero emissions and low noise (≤75dB), suitable for indoor and environmentally sensitive areas. The hydraulic system adopts energy-saving hydraulic pumps and valves, reducing energy loss and improving energy utilization rate.
