Potal Crane

Portal Crane, Dock Crane, Shipyard Crane are mainly used in the port, shipyard, ships at wharfs for mechanized handing and transshipment.Portal crane generally includes the  following units: steel frame, lifting mechanism, slewing mechanism, traveling  mechanism, spreader device(hook, grab, container spreader as your demand).Electrical equipment and other accessory  equipments for safety. Steel structure include jib and A-frame, slew platform  and gantry frame.Portal crane is extensively applied to dock's bulk  cargo (coal, ore and so on)and other cargo ship(lorry)loading and unloading as  well as slipway repair.1.Max lifting weight: set according to  customer requirements2.Application place:dockyard, pier, quey,  port ,rail 3.Works security and stability4.Motion: Hydraulic / Electric drive5.Crane structure:wheel mechanism,end beam  ,pillar with round platform, column with operator cabin luffing boom.6.The max lifting capacity, and the largest  boom length is setting accoding to customers requirements.7.The body mounts on the pedestal by  slewing bearing.8.The prime mover of crane can adopt  electric-hydraulic or engine-hydraulic.Mobile shipyard single jib used portal  crane are mainly used in the port, shipyard, ships at wharfs for mechanized  handing and trans shipment. it includes lifting mechanism, traveling mechanism, rotary mechanism, luffing mechanism. Engineers will design the  portal crane according user requirements.Lifting Mechanism:  Gear box   Lifting motor   Lifting brake   Lifting fan    Cable drum Traveling mechanism:Rail safety device Travel stop buffer  block  Anchor device  Traveling wheel    Full  set electric equipmentLuffing Mechanism:   Jib  A-bracket   Wire rope   Full set electric equipmentRotary Mechanism:   Turntable    Rotary gear  Full set electric  equipment
