Leesa Heavy Machinery 25-tonne Truck-mounted Crane

Leesa Heavy Machinery 25-tonne Truck-mounted Crane

As a core product under Foton Leica—a joint venture between Foton Motor and Daimler—this 25-tonne crane embodies the modern crane philosophy of ‘efficiency, reliability, intelligence and comfort’. It serves not merely as a lifting tool, but as a comprehensive solution empowering users to enhance construction efficiency and profitability.

I. Core Performance: High Efficiency, Energy Saving, Strong Operational Capability

Exceptional Lifting Performance:

Long Main Boom, High Lifting Height: Typically employing a five-section U-shaped or elliptical main boom, the fully extended reach exceeds 40 metres. This can be further extended via a jib, covering most mid-to-low-rise construction, municipal works, bridge projects, and equipment installation scenarios.

Large Lifting Moment, Extended Working Radius: Within its tonnage class, its lifting capacity in key operating conditions (e.g., medium-long boom, fully extended boom) typically leads the industry, offering broader operational coverage.

Highly Efficient and Energy-Saving Power System:

The chassis is predominantly equipped with Foton Cummins or Mercedes-Benz technology engines, delivering robust power with outstanding fuel economy.

The upper structure employs a variable pump-controlled hydraulic system that intelligently adjusts power output based on actual load. This achieves ‘fuel savings during light tasks and ample power during heavy duties’, resulting in significantly lower overall fuel consumption compared to traditional fixed-displacement pump systems.

Dual-pump parallel flow technology: During compound operations such as lifting and boom extension, dual-pump oil supply enables faster movement speeds and higher operational efficiency.

II. Intelligence and Operability: Precision, Safety, and User-Friendliness

Intelligent Control System:

Fully Electric Proportional Control: The joystick delivers precise, lightweight operation with exceptional micro-movement capability, enabling effortless high-precision lifting.

Intelligent Safety Protection:
Equipped with a torque limiter (black box), it displays real-time data including load weight, boom angle, jib length, and operating conditions. It automatically calculates and controls the safe operating range, triggering alarms and restricting hazardous movements during overload situations. This constitutes the core safety configuration.

Automatic Operating Mode Planning:
Multiple fixed operating modes can be pre-set and automatically recalled, eliminating human configuration errors.

Operational Visibility and Convenience:

Features fully covered walkway plates with spacious, secure passageways.

The cab is spacious and well-lit with unobstructed visibility, featuring standard air conditioning and an adjustable seat to minimise fatigue during extended operations.

The hook block pulley ratio can be switched manually or automatically to accommodate different requirements: high speed for light loads or low speed for heavy loads.

III. Chassis and Reliability: Balancing Mobility and Operational Performance

Specialised Full-Axle Chassis:

Features a heavy-duty crane-specific chassis with a robust frame and exceptional load-bearing capacity.

Full-axle drive and steering (configuration dependent): Ensures superior off-road capability and manoeuvrability across challenging terrains.

Cab Comfort: Incorporates a wide-body cab platform identical or comparable to that of the Eurocargo heavy-duty truck, delivering outstanding comfort during long-distance transfers.

High Reliability and Durability:

Core structural components (e.g., turntable, boom, chassis) utilise high-strength steel and advanced welding techniques, undergoing rigorous stress analysis and testing for exceptional longevity.

Hydraulic and electrical components predominantly feature international first-tier brands such as Bosch Rexroth, Eaton, and Siemens, or leading domestic alternatives, ensuring assured reliability.

IV. Economic Efficiency and Service Assurance

Exceptionally High Return on Investment (ROI):

High efficiency and fuel economy directly reduce operational costs.

High reliability and low failure rates ensure high availability, minimising downtime losses.

Robust operational capabilities enable undertaking more complex projects, enhancing per-unit productivity.

Foton Leasa's Robust Support System:

Financial Services: Flexible financing solutions lower equipment acquisition barriers.

Service Network: Leveraging Foton Group's nationwide service infrastructure ensures rapid response times and ample parts availability.
