MG Double Girder Gantry Crane with double girder lifting hoist
MG Double Girder Gantry Crane with double girder lifting hoist mainly consisting of the skeleton structure, lifting and cross traveling mechanism, long traveling mechanism, cabin and electrical control system. The trolley can move horizontally on a pair of rails on the beam. The beam can be box or trussed type in according to your working environment situation. Trussed type gantry crane is always using in outdoor, cabin used for operating, with seats inside. MG Double Girder Gantry Crane (Box-type) is composed of gantry, crane crab, trolley traveling mechanism, cab and electric control system, and the gantry crane can be Box-type or Truss-type structure. The track is at the side of each girder and the leg is divided into type A and type U according to user’s requirements. The control method could be ground control, remote control, cabin control or both.
Ordinary gantry cranes These cranes are mostly box-type and truss-type structures and are the most widely used. It can handle all kinds of articles and bulk materials with a weight of less than 100 tons and a span of 4 to 39 meters. Ordinary gantry cranes with grabs have a higher working level. Common gantry cranes mainly refer to hooks, grabs, electromagnetic, hoist gantry cranes, and also include half-gantry cranes.
Hydropower station gantry cranes are mainly used for lifting and opening and closing gates, and can also be installed. The lifting capacity is 80~500 tons, the span is small, 8~16 meters; the lifting speed is low, 1~5 meters/min. Although such cranes are not often lifted, they are very heavy once they are used, so it is necessary to raise the level of work.
Shipbuilding gantry cranes are used to assemble hulls on the hull. There are two hoisting trolleys: one with two main hooks running on the rails on the upper flange of the bridge; the other with one main hook and one auxiliary hook. Running on the rails of the lower flange of the bridge to flip and hoist large hull sections. The lifting capacity is generally 100~1500 tons; the span is 185 meters; the lifting speed is 2~15 meters/min, and the fretting speed is 0.1~0.5 m/min.
Advantages: compact structure, resonable layout, safe reliability; convenient maintenance, excellent swivelling function advantages.
Applications: It is the ideal lifing equipment in factories, mines, agriculture, electric power, construction building site, dock and warehouse for installation of the machines, lifting the cargos, loading and unloading the trucks.
Crane traveling mechanism adopts even driving form, and divided into two solutions:
The motor has a soft start characteristics, if it is not connected with starting resistance, there is no necessary to take other technical measures, power feeding directly, then it can reach the effect of "soft start" ., the motor itself with a flat friction brake, braking speed is adjustable. there is a very significant improvement on the impact for crane start and stop, the deceleration system is using closed hard tooth surface gear, grinding fine processing, smooth transmission, low noise, high load capacity, low temperature, long life.
