The 10 positive aspects of DaHan tower crane 

  1. With fifty six,000 sets of market quantity and excellent status, EPT tower crane ranks the initial location in China tower crane ept in the earlier a long time. EPT constantly adheres to the benefit that source the most valuable tower crane and support for the customer, with the maximum expense efficiency in the industry. 


two. EPT tower crane owns the top engineering R&D staff, the item top quality handed a number of experiments with strict tests. In any other case, EPT has sixteen years of manufacturing technology and rich ordeals in high quality administration. Till now, above 100 countrywide technological innovation patents of tower crane have been set into use already.

three.In order to promise the dependability of tower crane high quality and decrease the value, all uncooked materials are immediately provided by popular makes like Baosteel and Wisco. Uncooked supplies for major components such as normal segment major limbs, tower caps adopt Q345B metal, therefore the tensile toughness improved by 30% and the tower crane gets more safe and reputable. 

four. EPT tower crane is the company which firstly started out to use the robotic welding strains. At existing, we have a fully automatic robotic welding production line for mast sections fabrication manufactured up by more than a hundred welding robots. The generation line is composed with automated materials planning, welding and maching. All primary areas of EPT tower crane use robotic welding, with the most ept carbon dioxide blended with argon fuel shielded welding, it has deep depth of fusion, large quality of welding and secure performance.


five. All elements and components of EPT tower crane use top quality brands. Electric powered equipment with Schneider converter, aviation plug, stainless metal distribution box and three linkage console has functions of reduced failure price and easy set up.
Hoisting system is supplied by leading maker Jiangte Motor or HangZhou Shengjian, all with motor oil, totally free maintenance, higher reliability and low routine maintenance price.
Slewing support utilizes HangZhou Fangyuan manufacturer or Rothe Erde manufacturer, 2 times tempering processing can make a lot more effortlessly operation and for a longer time tower crane service existence.


six. Consideration to deFriction-disc torque limiters use friction get in touch with between mating discs to transmit electricity — and function considerably like friction-disc clutches in that overloads cause slipping amongst the discs. Friction-disc torque limiters excel in purposes necessitating continual managing and reasonable adherence to a safe-torque placing for basic safety. When mounted onto motor-pushed equipment, these torque limiters let axes to power by way of partial jams making use of motor inertia to carry on software of torque. That stops nuisance stops throughout momentary load boosts … however throughout real overloads and inertial shock loading, the torque limiter slips continuously to shield the method from hurt.tail quality.  High-toughness bolt adopt shipborne scale DACROMET technologies. It can maintain not rusted for 10 a long time .Swiss screw-thread bolts of preload market thirty percent than classic bolts. Fat limiter makes use of the stress ring structure and solid aluminum shell utilised Hoisting, derric ept limiting stopper to increase support daily life.


7.Huge constructions as mast area, turn able, leading package and hoisting jib adopt superior gear as NC device tool, drilling machine, milling machine processing following welding. That successfully assures merchandise assembly precision, minimizing the failure fee and improving the safety.

8.twelve automated spraying assembly line, the total equipment adopt impeller blasting to ensure the cleanliness of metal floor and eliminate the inner tension generating in welding procedure, increase the energy and steel area hardness, improve portray adhesion. Two primer, a paint spraying technological innovation, beautiful look, corrosion resistance has increased much more than twice than the daily life of normal spraying method. Platform, the tiny automobile, fence and other tiny items adopt hot dip galvanized after acid phosphate therapy, rust resistance stronger.


9.Hoisting, derric ept and slewing mechanism, with total basic safety this kind of as torque, fat limit. The metal wire rope broken rope unit. Range of the automobile style against decline and broken shaft, this sort of as tilting gadget. The electrical adopts overload security, the style of PLC self-prognosis method, it really is convenient to maintenance.


ten. EPT 3 production bases is ZheJiang , ZheJiang , ZheJiang . EPT tower crane are exported to a lot more than fifty nations around the world and regions. We have far more than 1000 sets after-income support community. We carried out the earliest stagnation level services manner in this tower crane ept that ensure the quality of service and efficiency. Otherwise, better to remove customer’s concerns.
