XCMG SQ8SK3Q Truck Crane

SQ8SK3Q Telescopic Boom Crane

1. Throttle Control System

This system replaces the traditional method of operating the control levers and throttle separately, enabling synchronized control of both levers and automatic acceleration and deceleration linked to the throttle. The smooth speed transitions make lifting operations easier and more fluid.

2. Automatic Hook Retraction System

This system minimizes preparation time before and after operations, ensuring the vehicle can be ready for travel as quickly as possible. It also prevents accidents caused by hook swinging that could damage the crane, thereby enhancing operational safety.

3. Hoist Over-Winding Protection Device

In the event of operator negligence or unfamiliarity with hook operation, this device promptly stops the hook from rising, preventing wire rope breakage that could endanger personal safety and property.

4. Swing Locking Device

The swing locking device ensures that the boom does not sway due to centrifugal force while the vehicle is traveling or turning, thereby preventing various accidents caused by swaying.

5. Dual-Pump Parallel Flow Technology

The hydraulic system employs dual high-pressure gear pumps and uses a multi-way valve to achieve parallel flow in the hoisting circuit, thereby increasing hoisting speed; it also supports the crane’s composite motion operations.

6. Torque Limiter

An optional torque limiter overload protection device is available to prevent users from performing overloaded operations due to negligence or unfamiliarity with lifting principles, thereby avoiding accidents such as vehicle rollovers and crane damage.
