Advantages of QD hook overhead crane:

QD hook overhead crane is suitable for loading, unloading and handling of ordinary heavy objects, and can also be equipped with a variety of special cranes for special operations, and can also be designed and manufactured according to the span required by users.

Features of QD hook overhead crane:

  1. QD hook overhead crane is mainly used in various indoor workshops. According to the different utilization level and load state, it is divided into A3, A4, A5, A6, A7 working levels.
  2. The entrance direction of the cab platform is divided into three types: side entrance, end entrance and top entrance.
  3. The driver’s cab can be installed at the left end or at the right end.
  4. Safety sliding contact wire or angle steel can be used for the conduction of the cart, either on the opposite side of the driver’s cab or on the same side of the driver’s cab.
  5. The operation of the crane is all completed in the driver’s cab.
  • All steel plates of the crane go through the steel pretreatment production line, shot blasting-primer spraying-primer drying-eliminate the internal stress of the steel plate, effectively increase the adhesion between the primer and the steel plate, and ensure the appearance of the product.
  • The blanking of the steel plate adopts a full set of German Messer CNC plasma cutting machine, which has fast cutting speed, small deformation and high precision, and the error can be controlled within 1mm. It can meet the high quality standards of raw materials and reach the industry-leading level.
  • Using steel plate coil or seamless steel pipe, Weihua has an industry-leading steel plate coil production and processing production line, from 1250t press pre-bending, to three series coiling machine rolling, and then to the cylinder longitudinal seam and circular seam automatic welding center welding and heavy-duty CNC horizontal lathe barrel machining,
  • The end beam welding adopts double-gun gantry submerged arc welding, which effectively guarantees the stability of product welding quality.
  • The main beam is the first in the industry to adopt efficient and intelligent welding robots. The inner seam welding of the main beam adopts advanced MAG welding, using Ar+CO2 mixed shielding gas, and the four main welds on the outer side of the main beam are welded by submerged arc automatic fillet welding machine.
  • The main butt welds and fillet welds of the main girder plates adopt radiographic inspection and ultrasonic inspection to ensure the quality of the welds.
