Reliability
SY55C is improved on aspects of structural member reinforcement and low failure rate etcOverall reliability leads in the industry.
Top-ranking core configuration
Core configuration
--lsuzu engine meeting emission standard national ll exclusively for SA-NY could ensure the operating reliability of the machineunder severe conditions.
--Rexroth main pump, Rexroth main valve and hydraulic components from world famous brands ensure high reliability of hydraulic system.
--Reinforced structural members with brand-new design have longer service life.
--The total weight is much larger than that of other companies and the stability is higher.
More powerful energy
Power system
--Ultra-light power engine exclusively for SA-NY: Power margin is sufficient, and service life is extended by over 10%.
--New-type parallel radiator: Coolant temperature is 3-5°C lower than the competitor and hydraulic oil temperature is 7-10°Clower than the competitor.
--External-mounting fuel filter: lt has high capacity and strong assimilative capacity, and is equipped with ultra-large capacity dual oil-water separator.
--Air prefilter + dual air filter element could ensure sufficient and clean air and reduce the wear of cylinder components.
Durable structural members
Boom
--Rear support and center support of the boom adopt forgings for avoiding concentrated local welding stress and improving the durability.
--Key positions are enveloped with fortified steel plate for severe working conditions.
Arm
--Rear support is made of forgings for avoiding concentrated local welding stress and improving the reliability With wear-resisting plate on front end, the service life of bucket rod is extended.
Bucket
--lt is reinforced bucket for rocks and is fitted with wear-resisting steel plate at the bottom so that the strength of bucket is improved.
--With secondary arc shape of optimized design, the digging resistance and the wear of sand and rock against the bucket body when digging so that it saves energy and is more durable.
