12 wheel Sinotruk Howo 15tons knuckle boom truck Tunisia

Name: 12 wheel Sinotruk Howo 15tons knuckle boom truck Tunisia
Brand: Sinotruk HOWO

The 12 wheel Sinotruk HOWO 15 tons knuckle boom truck is a 6x4 heavy-duty crane vehicle built on a ZZ3257N3847A chassis with a 371 HP diesel engine and 10 speed manual gearbox. It is designed for construction, infrastructure, and industrial sites where a mobile crane must operate independently without external lifting support. The truck-mounted knuckle boom crane can rotate 360 degrees, extend and lift up to 15 tons, and is suitable for loading and unloading heavy materials in remote or low-access areas. It is used by contractors, utilities, and municipal fleets in countries including Tunisia, Nigeria, and Kenya where road conditions and site access limit the use of larger mobile cranes.

Comparison

How It Compares With the Alternatives

8 wheel knuckle boom truck with 10 ton capacity	Lower lifting capacity but better maneuverability in urban or narrow access areas
Mobile crane on a flatbed trailer	No need for a separate towing vehicle and faster deployment, but less lifting height and reach
Telescopic boom crane on a 6x4 chassis	Better stability on uneven ground but less reach and less compact when folded

Operating Notes

Use Guide

Confirm left or right hand drive and local road regulations before placing the order
Inspect the crane and chassis for damage upon delivery and report any issues immediately
Use the radio remote control or top seat control only after checking the surrounding area for personnel and obstacles
Do not exceed 15 tons lifting capacity or the maximum boom reach specified in the manual
Perform daily checks on hydraulic fluid levels, cable tension, and brake function
Store the crane in the folded position and secure all components during transit
Free operator training is available at the factory before shipment
