1. Product Overview

The HOWO knuckle boom crane truck, also known as truck-mounted crane, Lorry Crane or Loader Crane, is a specialized multifunctional engineering vehicle that integrates a hydraulic crane system with a modified heavy-duty HOWO Cargo Truck chassis. It is professionally designed for lifting, lowering, loading and transporting heavy loads, perfectly combining flexible road mobility and powerful lifting capability in one single unit.

This Crane Truck adopts a portable hydraulic knuckle boom installed on a reliable HOWO truck base. Compared with telescopic booms, the folding knuckle boom features a more compact structure and more flexible operation. The complete vehicle structure consists of four core parts: heavy-duty truck chassis, standard cargo bed, hydraulic crane (knuckle boom / telescopic boom optional), and hydraulic stabilizer outriggers.

The product covers wide lifting capacity ranges from 2 tons to 20 tons for small and medium-duty operations, while customized heavy-duty models can reach over 100 tons to meet ultra-heavy load requirements. With integrated lifting and transportation functions, the HOWO knuckle boom crane truck is widely recognized for construction, logistics and municipal utility working conditions.

2. Working Principle

The HOWO Knuckle boom truck mounted crane adopts mature hydraulic transmission working principle. The vehicle chassis provides power to drive the hydraulic system, realizing stable hydraulic lifting, boom extending and folding actions. The crane supports 360° full free rotation, enabling omni-directional material handling without dead working angles.

Before hoisting heavy cargo, the hydraulic stabilizer outriggers are fully stretched to form a stable supporting base, effectively improving vehicle balance and ensuring safe and stable operation during full-load lifting. The knuckle boom folds freely through hydraulic control, allowing flexible adjustment of working radius and lifting height according to different site environments. The whole working process is smooth, precise and easy to operate, suitable for long-term continuous operation.

3. Daily Application Scenarios

Benefiting from its high versatility and flexible mobility, the HOWO knuckle boom crane truck is widely applied in multiple industries. It covers core working scenarios including construction engineering, logistics cargo handling, municipal engineering and emergency rescue.

It is commonly used for building material transportation, steel handling, street maintenance, urban infrastructure construction, heavy equipment moving and field rescue tasks. Especially with the compact folding boom design, it performs excellently in narrow construction sites, urban communities, roadside limited spaces and low-height working environments where traditional straight boom cranes cannot work smoothly.

4. Comparison With Traditional Models

Compared with traditional ordinary cargo trucks and separate fixed cranes, the integrated HOWO knuckle boom crane truck has obvious competitive advantages. Traditional working modes require separate purchase of transport trucks and lifting equipment, resulting in high procurement costs, low equipment utilization and complicated scheduling.

This Howo Crane Truck realizes dual functions of lifting and transportation in one vehicle with extremely high versatility. Different from straight boom cranes, the knuckle boom adopts a folding compact structure, which saves more parking and working space and greatly reduces daily operating costs. In addition, traditional lifting equipment lacks stable supporting structure, while our truck is equipped with professional stabilizer outriggers to ensure excellent stability and higher safety during operation. With superior flexible mobility, it can quickly reach various complex and narrow working sites that large traditional equipment cannot access.

5. Vehicle Purchase Guide

When purchasing a truck-mounted crane, customers can select suitable configurations according to actual working environments and load demands. For narrow working sites, low-space construction and urban municipal maintenance, the HOWO knuckle boom crane truck is the most ideal choice due to its compact folding structure and flexible operation.

For general small and medium-duty cargo handling and construction work, the 2–20 ton models fully meet daily operation needs. For ultra-heavy load engineering projects, customized heavy-duty versions above 100 tons are available. If you need both long-radius lifting and flexible folding performance, you can choose between telescopic boom and knuckle boom types according to your actual site conditions. The genuine HOWO chassis guarantees stable performance, low failure rate and strong road adaptability for long-term outdoor work.

6. Operation and Maintenance

6.1 Standard Operation

Before operation, inspect the truck chassis, hydraulic oil status, boom structure and outrigger flexibility to ensure no abnormal conditions. During operation, fully extend the stabilizer outriggers to ensure stable vehicle support. Operate hydraulic lifting, folding and rotation actions slowly and smoothly, and strictly prohibit overload operation and violent manipulation. Adapt working speed according to site space to ensure safe and efficient material handling.

6.2 Daily Maintenance

Regularly replace hydraulic oil and filter elements to keep the hydraulic system clean and stable. Check the connecting parts of the knuckle boom, folding joints and outriggers regularly to prevent loosening, jamming and oil leakage. Clean dust and sundries on the crane surface and chassis regularly to reduce component wear. Standard daily maintenance can effectively reduce failure rate and extend the service life of the entire vehicle.
