Portal crane is a multi-purpose crane machine which is extensively applied to loading and unloading all kinds of cargos at various working site. The main structure is steel frame. The lifting tools can be grab, container spreader, hook and electromagnet, etc. This crane has two different type according to the working demand: stationary type and travelling type.
Portal crane can meet high efficiency work requirements, with the advantage of heavy lifting capacity, calm movement, high working efficiency, safety and reliability, compact frame, comfortable operation, nice appearance, convenience maintenance and so on. It can work perfectly in the limited space of the port, yard and other places, and is excellent on truck transportation, ship loading and unloading. And especially at the general use port, portal crane is a kind of material handing machine which can bring you swiftness benefit with small investment.
High Quality Material and Components
The steel plates are all from Bao steel, Wuhan steel, Handan steel, all steel should be inspected by our National Technology Test Laboratory to ensure the quality.
The motor, gear box can be China top brand or International brand. The main electric unit can be Siemens, Schneider, ABB.
Modular Design
The component of crane are designed into various series standard modulars. And different modulars can be assembled to different products.
All the modular components can assembly and disassembly for good transportation.
Standard modular components can be manufactured with short producing time and steady quality. So that we can short the delivery time.
Advanced Manufacturing Technology
Pretreat
Both side of all the steel plates of crane are pretreated by pretreatment production line, Sand blasting-- Primer spray--Primer drying. Eliminate the inner stress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.
Cutting
Steel plate cutting adopts whole sets Messer CNC plasma cutting machine from Germany, with very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1mm, it can ensure the raw material at high quality standard and can reach top level in the industry.
Welding
The welding of main beam adopts high efficiency and intelligent welding robot, Weihua are No.1 enterprise who adopts this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adopts automatic submerged-arc fillet welding machine. The welding of main beam adopts radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position.
High Security
Overload limit monitor, it can shows the loading capacity and help the operator to avoid overload.
Automatic checking system, the controller can check the effectiveness of power voltage, the default Phase protection device and zero position of all buttons.
The driving and driven wheels have edge brake, and the brake interlocks with the electric to avoid crane from gliding so that can improve the safety.
