Excess weight limiter uses the stress ring composition and cast aluminum shell utilised Hoisting, derric ept limiting stopper to lengthen services existence.



seven.Huge structures as mast section, switch ready, prime kit and hoisting jib undertake advanced products as NC machine resource, drilling equipment, milling machine processing after welding. That successfully ensures merchandise assembly precision, minimizing the failure charge and enhancing the safety.


8.twelve automated spraying assembly line, the complete device undertake impeller blasting to guarantee the cleanliness of steel area and eradicate the internal pressure producing in welding process, boost the strength and steel surface area hardness, enhance painting adhesion. Two primer, a paint spraying technology, gorgeous appearance, corrosion resistance has increased a lot more than two times than the lifestyle of common spraying approach. Platform, the little auto, fence and other tiny parts adopt sizzling dip galvanized after acid phosphate remedy, rust resistance much better.


9.Hoisting, derric ept and slewing system, with complete security this kind of as torque, weight limit. The metal wire rope broken rope system. Variety of the car layout in opposition to loss and broken shaft, this sort of as tilting unit. The electrical adopts overload protection, the design and style of PLC self-analysis method, it really is handy to upkeep.



ten.Dahan three production bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to more than fifty countries and areas. We have much more than a thousand sets soon after-product sales service community. We carried out the earliest stagnation point provider manner in this tower crane ept that ensure the top quality of service and performance. Otherwise, better to get rid of customer’s problems.
