Rope Release Method: Flexible and Customized Solutions
Experience versatility with two distinct rope release options: inner rope out and outer rope out. Each method is crafted to meet specific customer needs, ensuring tailored efficiency.
Prior to crane operation, a thorough inspection of the steel wire rope's clamp is essential. Ensure the rope clamp secures the wire rope and check if it's properly seated in the groove. Should the rope exhibit twisting, creasing, wear, severe corrosion, breakage exceeding 10%, diameter reduction over 7%, or discoloration from overheating, immediate replacement is imperative.
Hydraulic Oil Cylinder: Precision in Motion
Our crane's extension and retraction are governed by a robust oil cylinder mechanism, delivering reliable performance.
Select from single or double cylinder oil systems for optimal control and power.
Balance is key; a balance valve between the telescopic rods ensures seamless boom extension and retraction.
Crafted for resilience, the oil cylinder barrel undergoes quenching and tempering treatments, providing exceptional tensile strength.
The piston rod, hardened and tempered, is coated with hard chromium for outstanding rust prevention and wear resistance.
Our sealing components meet the highest standards, tailored to withstand the demanding conditions of the host machine.
High Quality Slewing Support: Advanced Engineering at Your Fingertips
Often referred to as the "joints of machines," rotary bearings deliver seamless motion for superior functionality.
Our small tonnage truck-mounted cranes feature integrated slewing supports, while large tonnage variants employ split slewing supports for enhanced performance.
Experience limitless maneuverability with our crane's infinite 360° rotation capability.
Rear Outrigger: Stability Meets Customization
