50/10 Ton Customized Outdoor Double Girder Rail Gantry Crane
Structure:
The electric double-girder gantry crane is composed of cart running
mechanism, lower beam, outriggers, driver's cab, main beam, trolley
running mechanism, hoisting mechanism, escalator, electrical
appliances and other components:
1. Cart running mechanism
It is mainly composed of a lower beam and a trolley, of which the
trolley is composed of a driving wheel group and a driven wheel
group. The running mechanism includes a motor, a reducer, a gear,
and a wheel group.
2. Outriggers
The section steel is used as the material, and then welded into a
cage-shaped mechanism, the lower end is connected with the lower
beam, and the upper end is connected with the main beam bolts
through flanges.
3. Cab
The skeleton is made of profiled steel, the outer shell is welded
on the skeleton with thin steel plates, the driver's cab is closed
with broken lines, and the electrical appliances, power
distribution cabinets and lines of the operating mechanism are
generally located in the driver's cab.
4. Main beam
The section steel and the steel plate are welded, generally welded
into a truss triangle. On the main beam, there are also trolley
running rails.
5. Trolley running mechanism
The main components are similar to the running mechanism of the
cart. The motor is driven by the reducer, and the pinion on the
reducer is then transmitted to the large gear, so that the cart can
travel back and forth.
6. Lifting mechanism
It is installed on the trolley frame, and the lifting movement is
realized through the hoist and the matching fixed pulley, movable
pulley or hook.
