RMG Type Upper Rotation Rail-mounted Container Gantry Crane

Description

The rail-mounted container gantry crane (English abbreviation RMG) is one of the special machines for container yards. It uses mains electricity to move on the track through the traveling wheels, and is equipped with 20′, 40′ retractable spreaders (can also be equipped as needed) Double container spreader), lift and stack containers within the specified range of the container yard. Compared with RTG (tired container gantry crane), RMG has the advantages of being driven by mains electricity, pollution-free, can increase the lifting capacity and lifting speed, and the truck can lift goods and move quickly. This machine consists of a lifting mechanism, a trolley operating mechanism, a cart mechanism, an anti-rolling mechanism, etc. The lifting, cart and trolley mechanisms are mostly controlled by AC frequency conversion. The lifting mechanism is generally in the form of a single drum, and can also be designed as a double drum open type according to needs.

Working Condition

1. Metal structures and mechanical parts should have sufficient strength, stiffness and buckling resistance.

First of all, it is required that parts and metal structures are not damaged after being loaded. For parts such as steel wire ropes with complex stress states, static strength calculations are usually performed with a higher safety factor based on the main load and main deformation form. It must also be required that the deformation of the component under load is within the allowable range, that is, it should have sufficient stiffness.

2. The whole machine must have relatively high anti-overturning stability.

3. The prime mover has the power to meet other requirements, and the braking device should provide the necessary braking torque.

Features

Precision positioning rotating trolley, automatic telescopic lifting device, eight rope anti sway mechanism in space, effectively preventing swinging and twisting of the lifting device (there are two ways to support container rotation: lower lifting device rotation and upper trolley rotation)

Technical Data

Spare Parts

Main beam

The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).

Ground beam

The lower beam is also a box-shaped structure, mainly composed of cover plates, webs, ribs, flange supports and other parts. The production process is similar to that of the main beam and other box beams. After the lower beam structure is completed, the bent plates are assembled according to the drawing. The flange support is welded to the lower beam after the lower beam is made to ensure the level of the flange surface. When the lower beam and the leg are assembled, the flange on the flange made on the leg is welded to the leg. The appearance quality and geometric dimensions of the lower crossbeam after production meet the requirements of the standard GB14406-93.

Trolley

Crane trolley is a load-bearing equipment that can travel along the running track, transport goods, and lift operations. It is usually used as a supporting component for large lifting equipment such as bridge cranes, gantry cranes, gantry cranes, and cantilever cranes. It is mainly used for logistics handling and heavy lifting operations in factories, docks, shipyards, and other places.

Crane remote control

Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.
