3.Marine Crane Feature:
Advanced decelopment & Analysis means make sure design is reliable.
Using two-telescopic cylinder design,one of the cylinder push the second large boom,another cylinder push therest of telescopic boom by the pulley block and wire rope.To ensure that the crane has strong listing capacity in the middle distance and effectively protect the wire rope in the boom.
The more symmetrical center design of pentagon&heptagon boom make it has bigger anti-bending capacity.
Compact boom head and tail desigh,make the longest boom length,prolong the working ise of the crane.
Adopt the built-in telescopic wheel design,the advantage is to design a larger pulley diameter and improveloading ,telescoping capacity.Then it can protect the telescopic steel wire rope and extend its life.
Boom head adopting intefral strcture,greater intensity(spit head desigh reduces the boom head carrying capacity)
Rotary organizations adopts a low speed,high torque rotary motor,by disc springs and friction plate to brake,it will be more stable,and outputting larger torque.At the same time,absorbing the stronger inertia of crane effectively during the braking process.When rapid braking,the friction plate can absord large amounts of energy to protect the whole crane steel structure.
Lifting mechanical hydraulic winch relies on disc spring and friction brake,stable and reliable,eddicicent,low noise,small calorific value.Rely on hydraulic balanced valves balancing weights when falling,greatlyimprove products reliability.
The crane boom adopt the larger slider design to reduce the lazy arm specific pressure,at the same time to reduce the wearing capacity
