30t Shipyard Gantry Crane are mainly used in the loading and unloading in building materials, petroleum, petrochemical, ports, railroad yards, stock yards, and bulk cargoes.
(1)High site utilization
(2)Large operating range
(3)Wide adaptability and versatility
(4) Genneral used to handling 20ft or 40ft containers.
Shipyard 30T+30T container handling gantry crane is suitable for loading and unloading in open warehouse, cargo yards, railway freight station, port and wharf area. So what do we supply to our customers?
Shipyard 30T+30T container handling gantry crane mainly have the following characteristics:
1.The lifting speed is low and the running speed of the long traveling is high. According to the demand of the container yard, the lifting height of the rail type container gantry crane is determined according to the 3 stacked containers together and the fourth can pass or the 4 stacked containers together and the fifth can pass. Because the lifting height is not high, the lifting speed is correspondingly lower. However, the container yard generally has a longer length along the track, which achieves a certain productivity and the running speed of the long traveling is higher.
2. The running speed of the trolley can be determined according to the span of the bridge and the extension distance between the two ends. When the span and cantilever length are small, the speed and productivity requirements of the trolley are relatively desirable. When the span is larger and the cantilever length is larger, the running speed of the trolley can be increased to meet the productivity requirement.
3. when the span is more than 40m, in the course of high speed operation of the long traveling, due to the different running resistance of the two sides of the door, the synchronization device is set up to keep the speed of the running speed of the running mechanism on both sides through the electrical control system.
4. In order to meet the requirements of high usage, the electric drive control system uses thyristor DC or AC speed control control system to achieve better speed control and control performance. Electrical control system can also be controlled by conventional AC eddy current speed control or AC stator voltage regulation and speed drive control system. For the electric control system of high speed car running mechanism, it usually uses thyristor DC, AC speed control control system or AC stator voltage regulation control system with electric brake, avoiding the way of braking on brake when running the conventional electric drive system, so as not to bring huge impact to the whole machine.
