XCMG 20 ton truck with crane SQS500B China telescopic boom lorry crane.
The SQS500B truck-mounted crane industry applies the self-developed hydraulic confluence proportional control technology for the first time, and further improves the work efficiency of the winch under the premise of the crane's micro-movement and stable compound action.
The telescopic system adopts the industry-leading double-cylinder touch mechanical stroke Control, sequence expansion and contraction are more reliable, and the load expansion and contraction ability is stronger.
1. Double-cylinder telescopic system and strong load capacity for one boom;
2. Good micro-movement and high working efficiency;
3. Self-locking performance is good; the action is more stable;
4. Higher stability of the whole vehicle;
5. It can promptly remind the operator will automatically cut off dangerous actions to ensure safe work;
6. XCMG special wide temperature hydraulic oil is standard, which can be used in winter and summer.
