Components

a. Gantry structure
DPT's gantry structure consist of double box main girder, A frame flexible leg, A frame or I frame rigid leg and spring bearing joint. The main girder is common welding structure of High strength low alloy structural steel Q345 with yild strength 345Mpa (refer to GB/T1591-2006). Q345 is widely used in crane structure,for its obvious advantages in ecnomic along such high strength low alloy structural steels.The spring bearing joint connect the main girder and the flexible leg. The main girder can free expand on a neoprene bearing to avoid rail gnawing.

b. Trolley
The trolley consist of trolley structure, hoisting mechanism, trolley travelling mechanism and safety system.Trolley structure is a welding structure of Carbon structural steel Q235 with yield strength 235Mpa or Q345. A limit switch was mounted on the trolley to limit the trolley travel distance. Buffers was mounted on the two end of the trolley to avoid demage when crash occur.

c. Hoisting Mechanism
DPT's Hoisting Mechanism consist of frequency conversion motor,coupling,brake, reducer, drum coupling,drum and wirerope system. The motor commonly used Jamusi's or Dalian's frequency conversion motor.The brake use chinese top brand Jingu or Huawu.The Reducer is hardened gear reducer.The drum use Q345 steel and the diameter ratio is greater than 18. The wirerope use Nantong or Guizhou wirerope with 18x7 structure, and it's tensile strength is 1670Mpa.The Pulley is hot rolled pulley or welding pulley with diameter ratio greater than 20. The hoisting Mechanism has been setted with overload switch and overspeed protection switch.

d. Trolley travel system
DPT's trolley travel system consist of motor, coupling, brake, hollow shaft reducer and bogies.Buffers mounted on the two ends of the trolley. Limit switches are mounted on one side of the trolley to avoid demage.Wheel block is always Right angle bearing box or Split bearing box. The right angle bearing box is the traditional type with widely praised. The split bearing box is advanced design type with advantages of easily assembly and maintenance. The wheel casted and machined with ZG50SiMn. The wheel has double wheel rims. The wheel rim has enough strength to avoid the trolley deviation travel.

e. Gantry travel mechanism
DPT's Gantry travel mechanism consist of bogies and triad reducers.Commonly the driven bogies are half of all bogies. The triad reducer mounted on the driven bogies. On the idle bogie there is mounted Wheel clamp or anti-wind shoes.Optional rail clamps are mounted under sill beam to instead wheel clamp. All these safety devices interlock with anemograph.On the end bogie there is rail clearer to clear blocks unexpected on the rail.There is also mounted rectifying wheel on the end bogie to avoid crook run. A lightning shoe mounted on the end bogie to conduct the lightning power to the earth.
