20 Ton Rail Mounted Gantry Crane Specifications Design

Table of Contents

20 Ton Rail Mounted Gantry Crane is double girder gantry crane, suitable for open freight yards and along railway operations, because its large leg space, it is suitable for lifting large volumes of goods, and also can lift containers, its gantry frame is similar with container crane.

20 Ton Rail Mounted Gantry Crane Specifications Design consists of gantry frame, trolley and crane long traveling mechanism, electrical system and other components. There also equipped with rail clamp, anchoring device, anemometer and corrective devices, etc. for outdoor work gantry crane.

20 Ton Rail Mounted Gantry Crane Specifications Design uses double beam and double track, single trolley winch structure. Crane winch trolley part include main and auxiliary hoisting mechanism, each mechanism using separate transmission set. Main and auxiliary hoisting mechanism not only can independently complete lifting, but also can be coordinated to complete the work of flipping objects.

Gantry frame structure same with A frame gantry crane, main girder, end girder, legs, saddles and lower cross beams are connected together by high strength bolts, using reaming bolts positioned on each flange plate, positioning marks have been completed before delivery. Its structure is similar with container gantry crane, which is more stable and firm.

To facilitate transport, handling and installation lifting on site, set with lugs and hanging holes on the crane main components for lifting. The intensity and location of these lugs and hanging holes are fully considering lifting safety and convenience.

Rail Mounted Gantry Crane Traveling Mechanism

20 Ton Rail Mounted Gantry Crane Traveling Mechanism

20 Ton Rail Mounted Gantry Crane traveling mechanism driving adopts motor drive the reducer through couplings and transmission shafts, reducer drive the driving wheels, which is smooth and reliable. This structural arrangement is conducive to each driving system component installation, maintenance and removal.

20 Ton Rail Mounted Gantry Crane Trolley

20 Ton Rail Mounted Gantry Crane Trolley mainly consists of lifting mechanism, trolley frame and trolley traveling mechanism.

20 Ton Rail Mounted Gantry Crane Hoisting Mechanism

20 Ton Rail Mounted Gantry Crane main and auxiliary hoisting mechanism arranged in the same trolley frame, each set up with separate driving device, main and auxiliary hoisting mechanism not only can independently complete lifting, but also can be coordinated to complete the work of flipping.

20 Ton Rail Mounted Gantry Crane Trolley Traveling

Trolley tracks using one whole railway that joints welding as integration, to ensure the trolley running well.

Trolley traveling driving type is same with the crane long traveling mechanism.

20 Ton Rail Mounted Gantry Crane Technical Parameter

Technical parameter is an indicator of the operational capability of 20 Ton Rail Mounted Gantry Crane, main parameters including: lifting capacity, lifting height, span, working level, working speed, etc., as shown in the drawings. Complete set of supporting components (such as reducer, motor, brake, etc.) operation and maintenance, please refer to the supporting manufacturing factory manual.

About 20 Ton Rail Mounted Gantry Crane Specifications Design

Here are a few key specifications to look out for when purchasing a rail mounted gantry crane:

Span: The distance between the centerlines of the gantry spans across the tracks.
Lifting height: the maximum height that the gantry crane can lift under full load.
Speed: The maximum speed at which the gantry crane can move under full load.
Working level: the load level of the gantry crane under different working conditions, such as A5, A6, etc.
Use environment: The requirements for the use environment of the gantry crane, such as rainproof, dustproof, shockproof, etc.
Combined with the space size of the site: the gantry crane needs to be installed in the designated site, and needs to be selected according to the specific size and space requirements.
Track type: The track type used by the gantry crane, including light rail and heavy rail.
Conductive form: The conductive form used by gantry cranes, including cables and trolley lines.

These specifications vary with gantry crane models, and the selection should be made according to actual needs and conditions.
