The ISUZU ELF 4x2 XCMG 5-Ton Telescopic Boom Truck-Mounted Crane is designed as a versatile lifting and transport platform for daily work on construction and industrial sites. Built on the ISUZU ELF 4x2 chassis and fitted with an XCMG KSQS125-4 telescopic boom crane, it provides reliable performance, compact dimensions and convenient mobility.
The vehicle adopts a 4×2 driving configuration with a GVW of 8,280 kg, curb weight of 4,990 kg and loading weight of 3,095 kg. With overall dimensions of 7,030 × 2,400 × 3,200 mm and a 3,815 mm wheelbase, the truck offers a balanced layout between chassis, crane and cargo box. This compact size allows the truck to operate efficiently on urban roads, construction sites and industrial facilities where space is limited.
Power is provided by the ISUZU 4HK1-TC51 diesel engine, delivering 190 HP and meeting Euro 5 emission standards. The rated power is 141 kW, with maximum torque of 510 N·m at 1,600 rpm and rated speed of 2,600 rpm. The engine is matched with a manual gearbox offering 6 forward gears and 1 reverse gear, providing smooth power output and good fuel economy for mixed road conditions. The truck uses 7.50R16LT 14PR tires and an axle load distribution of 3,000/5,280 kg, with a top speed of up to 105 km/h, meeting both urban and highway driving needs.
The cabin is a single-row left-hand drive design with air conditioning, offering a practical and comfortable working environment for the driver. The chassis brand is QL with model QL1080BUKAY, widely recognized for reliability in commercial applications.
The lifting system is the core feature of this vehicle. It uses an XCMG KSQS125-4 telescopic boom crane with a maximum lifting capacity of 5,000 kg and a maximum lifting moment of 125 kN·m. The crane provides a maximum hydraulic outreach of 11.2 m and a maximum lifting height of 12.5 m (telescopic boom), supporting a wide range of lifting operations. The slewing angle is 360°, enabling full-circle operation and flexible positioning of loads without repositioning the truck. The crane operates at a maximum working pressure of 22 MPa, with a recommended pump capacity of 40 L/min and an independent oil tank capacity of 90 L to ensure stable hydraulic performance.
The crane installation space is 900 mm, with an optimized layout designed to improve stability and ensure that the boom and chassis work together safely under rated loads. Protective structures made from Q235B carbon steel, welded for strength, enhance durability and resistance to harsh working environments.
Behind the crane, an integrated cargo box is configured with dimensions of 4,100 × 2,300 × 550 mm. This box can carry tools, equipment or supporting materials needed for lifting jobs, allowing the truck to combine transport and lifting functions in one vehicle. This reduces the need for additional support trucks and improves overall work efficiency.
Safety and reliability are also considered in the design. The reinforced boom structure, stable crane–chassis integration and carefully arranged installation space help ensure safe lifting within rated capacity. Components and materials are selected to resist corrosion and meet continuous operational demands. Proper use and maintenance, together with the operating precautions for straight boom truck-mounted cranes, further enhance long-term reliability.
With its compact ISUZU chassis, XCMG 5-ton telescopic boom and practical cargo box, this truck-mounted crane is suitable for contractors, construction companies, logistics operators and maintenance teams that require a flexible lifting and transport solution. It has been successfully applied in Middle Eastern countries, North African countries and some South American countries for various lifting tasks.

Durable structure: Q235B carbon steel protective structures and welded construction support long-term operation under demanding conditions.
Balanced performance: Reasonable GVW, axle load and top speed up to 105 km/h make it suitable for both urban and intercity deployment.
The ISUZU 4x2 XCMG 5-Ton Telescopic Boom Truck-Mounted Crane has already been exported to Middle Eastern countries, North African countries and some South American countries. In these regions, it is mainly used for:
Construction lifting on building and infrastructure projects
Loading and unloading equipment and steel materials in logistics and industrial zones
Utility and maintenance work requiring a combination of lifting capacity and road mobility
Feedback from these applications shows that the combination of ISUZU ELF chassis and XCMG KSQS125-4 telescopic boom meets the practical needs of customers under different climatic and working conditions, providing a stable and efficient lifting solution.
