Weihua crane gantry crane
Gantry crane: a gantry crane in which a horizontal bridge is arranged on two legs to form a gantry shape.This crane runs on the ground track, and is mainly used in open storage yard, dock, power station, port and railway freight station for handling and installation.Gantry crane lifting mechanism, trolley running mechanism and bridge frame structure, and bridge crane is basically the same.Because of the large span, the crane operating mechanism mostly adopts the separate driving mode, in order to prevent the skewed operation of the crane and increase the resistance, or even accidents.Gantry crane crane trolley in the bridge operation, some lifting trolley is a jib crane.The supporting legs on both sides of the bridge frame are generally rigid supporting legs;Spans more than 30 meters, is often a side for rigid leg, but on the other side through the ball joint and the bridge connecting the flexible leg, make the door frame statically determinate system, so that you can avoid outer load under the action of the additional stress due to the lateral thrust, also can compensate bridge longitudinal temperature deformation of the gantry crane windage area is large, in order to prevent the slide under the action of strong wind overturned or, with a sonde and interlock with running institutions of crane rail device.A bridge may be cantilevered at both ends;It may also be cantilever at one end or cantilever at both ends to extend the operating range.

The bridge frame of semi-gantry crane has supporting legs at one end and no supporting legs at the other end.Gantry cranes are divided into four types.
(1) ordinary gantry crane: the crane is the most widely used, can carry a variety of components and bulk materials.Weihua crane can produce a maximum weight of 900t gantry crane.The ordinary gantry crane with grab bucket has higher working level.

(2) hydropower station gantry crane: mainly used for lifting and closing the gate, but also for installation.Lifting weight up to 80 ~ 500 tons, span is small, 8 ~ 16 meters;The lifting speed is low, ranging from 1 m/min to 5 m/min.Although this kind of crane is not often hoisted, but once used the work is very heavy, so it is appropriate to improve the level of work.
(3) shipbuilding gantry crane: used for shipbuilding platform assembly of the hull, there are usually two lifting trolley: one has two main hooks, running on the bridge flange track;The other has a main hook and a secondary hook, which operate on the track of the lower flange of the bridge to flip and lift large hull sections.The lifting weight is generally 100 ~ 1500 tons;The span is 185 meters;The lifting speed is 2 ~ 15m/min, and the fretting speed is 0.1 ~ 0.5 m/min.
(4)Gantry container crane: used for container terminal.Tugcars can accelerate the turnover of container transport Bridges or other cranes by stacking the containers unloaded from ships onto the quayside container transport Bridges and transporting them to the yard or the rear of the quayside container transport Bridges and stacking them on gantry cranes or directly loading them onto trucks.Can pile up the container yard of 3 ~ 4 storeys tall, 6 rows wide, use tire type commonly, useful also have rail type.Container gantry crane is larger in span and height on both sides of gantry frame than container straddle truck.In order to meet the needs of port and wharf transportation, this kind of crane has a higher working level.The lifting speed is 8 ~ 10 m/min;The span is determined by the number of rows of containers that need to be spanned, and the maximum size is about 60 meters, corresponding to the lifting weight of containers 20 feet long, 30 feet long and 40 feet long, which are about 20 tons, 25 tons and 30 tons respectively.
