Railway closed rail crane
T crane with flat car fixed way into three kinds: 1, and the T crane base platform car beam welding directly; 2, the T crane base by high strength bolts and plywood and beams together. Advantages and disadvantages of the two kinds of fixed way, the first welding style suitable for its own car, welding can be removed from the base of the daily maintenance, strong and firm; Second way suitable for rental car, by the way, T can be removed at any time according to need, but because the base is bolted connection, all should strengthen daily maintenance.
T hang by the spiral arms of steel, electric hoist, slewing mechanism. Slewing steel boxes by beams, channels, such as welding type components, electric hoist moving along the beams bottom flange, rectangular steel pipe through welding strengthen the load-bearing column beam, slewing mechanism driven by electric or manual, consists of slewing bearing, gear motor, the motor through reducer drive rotary bearing to job position, meet the construction requirements.
T crane slewing mechanism can adopt two methods of manual and electric, if the use of electric drive rotary the whole device needs to consider the possibility of a sudden power outage equipment can't turning, so the equipment has increased in the design of speed reducer and the rotary support emergency separation device, to meet under the condition of no electricity to realize T crane slewing. Manual rotation is through human T crane beam end of traction rope free rotation.
