Truck Mounted Crane (SQ12 Straight Boom Crane)

SQ12 Truck Mounted Crane (Straight Boom Crane)

Characteristics
1. The SQ12 truck mounted crane is a straight boom crane. It features sable 360°rotation due to the employment of planetary reducer.
2. Front outriggers with full span of 5.56m are fixed rear outriggers used in our straight boom hoisting device, guaranteeing high machine stability. Apart from fixed rear outriggers, you can select hydraulic rear outriggers for higher machine stability and make the hoisting equipment adaptable for more complex working conditions.
3. A higher seat in the cab allows the operator to have a wider visual field to work safely.
4. Hexagon sections makes for good stability of our truck mounted crane.
5. The two-stage hydraulic telescopic cylinders are safe and reliable.
6. Operation of the truck mounted crane is controlled by the control valve located beside the seat.
7. The outriggers are controlled by dedicated control valves on both sides of the goods handling machinery. The use of selector valve helps prevent improper operation.
8. Our truck mounted crane is fitted with height limit switch, over winding alarm device and LED illuminating lamp.
9. Moment limiter is optional for this construction lifting equipment to make machine operation safer.
