About Portal crane

Four-link type portal crane has been extensively applied to loading and unloading at port and materiel handling at dockyard and metallurgy industry.The main structures are composed of steel frame,lifting mechanism,luffing mechanism,slewing mechanism,crane travel mechanism,spreader device (grab,container spreader,hook and electromagnet disk),electrical eqiupment and other accessouy eqiupment for safety.Steel structure include jib and A-frame,slewing platform and gantry frame.

Refereced criterion and standards are as follows:GB/T17495-1998 harbor portal crane techanical specifications,GB6067-85 lifting equipments safety regulation,GB3811-2008 crane design criterion,ISO standards,FEM standards and JIS standards.

Application

Port or harbour portal crane is used for loading and discharging cargos from ships or shipbuilding. It is suitable at various of ports and shipyards with the help of hook, hanger, grab, container spreader etc.

Feature

1. Common use of grab and hook, good adaptability, wide application scope.

2. Optimized double-link mechanism is adopted, high precision of level luffing.

3. Full slewing of 360 degree, wide operation scope.

4. PLC control, AC frequency speed control, steady and reliable operation.

5. Remote monitoring system can be installed according to the requirement of customers.

6. Adequate installation of safety, communication and illumination systems.
