Overview Base Mounted Jib Cranes have a heavy wall structural steel pipe mast and a reinforced large diameter base plate for minimal deflection and continuous alignment. Durable and long lasting overhead floor cranes feature a rolled steel I-beam section with tapered flange for smooth trolley travel. Safety end stops at both ends of boom limit trolley travel. Light Duty Cranes are used for hand chain or light duty electric hoists Product Advantage -Special designed reducer for reliable performance -Box girder (for bigger capacity) gives safety factors -Easy installation and maintenance -Limit switch for rotation, trolley and hoisting -Special painting material for outside yard -Special rotation designing for winding area (need to be clarified)
