XCMG SQ12SK3Q Truck Crane

SQ12SK3Q 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/deceleration linked to the throttle. The smooth variation in rotational speed makes lifting operations easier and more fluid.

2. Automatic Hook Return Device

This feature minimizes preparation time before and after operations, ensuring the vehicle can enter driving mode as quickly as possible. It also prevents crane damage caused by hook swinging, 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

This device ensures that the boom does not swing due to centrifugal force while the vehicle is traveling or turning, thereby preventing various accidents caused by such swinging.

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 and supporting 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 vehicle rollovers and crane damage.
