RMG Rail Mounted Gantry Crane

Rail-mounted container cranes are mainly used for container unloading, handling and stacking in container railway transshipment yards and large container storage and transportation yards. Rail-mounted container gantry crane is composed of main beam, rigid and flexible gantry legs, lifting trolley, crane running mechanism, electrical system, cabin room, etc.Rail mounted container gantry crane generally requires a large clearance in the width direction of the gantry leg, so the upper part of the gantry leg is opened into a U shape to connect with the upper part of the gantry leg, and a trolley maintenance frame is erected.

The rail-mounted container gantry crane can load and unload 20′, 40′, 45′ international standard containers. The lifting capacity is generally 36t and 40.5t. According to the site, container storage and transportation process and loading and unloading vehicles; The span can be divided into 26m, 30m and 35m; Cantilevers can be divided into non cantilevers, single cantilevers and double cantilevers; The upper trolley rotation and lower spreader rotation.

RTG Rubber Tyre Gantry Crane

The rubber-tyred container gantry crane is a special machine for stacking containers. It consists of a gantry frame, a power transmission system, a hoisting mechanism, a crane traveling mechanism and a telescopic spreader. The lifting trolley equipped with the container spreader walks along the main beam track to perform container loading, unloading and stacking operations.

The tire-type traveling mechanism can make the crane walk on the cargo yard, and can make a 90° right-angle steering to transfer from one cargo yard to another. , flexible work. According to the driving mode, the RTG can be divided into diesel engine-electric mode and diesel engine-hydraulic mode. The diesel generator system is generally arranged on the bottom beam, mainly composed of diesel generator sets, auxiliary devices and engine rooms.

UMG Double Girder Gantry Crane

UMG type Double beam gantry crane is an ideal handling equipment for outdoor operation. Cantilevers can be added on both sides of the main beam (usually the cantilever length is 1 / 4 of the span length), and the distance between straight legs can be increased to facilitate the passage of large goods from the straight legs.

The power supply can be provided by cables, sliding contact wires and diesel generators. Gantry crane has the characteristics of high site utilization, large operation range, wide adaptability and strong universality. It is widely used in port freight yard. In the port, it is mainly used for the loading and unloading of outdoor freight yard, stockyard and bulk cargo.
