Double beam gantry crane is a variant of gantry crane. There are double-beam gantry cranes, as well as single-beam gantry cranes. It is mainly used for loading and unloading of outdoor cargo yard, storage yard cargo and bulk cargo. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. They have been widely used in port cargo yards. Its metal structure resembles a door-shaped frame. Two feet are installed under the main beam, which can directly walk on the ground track. The main beam can have outriggers at both ends. Gantry cranes are bridge-type cranes where the bridge is supported on the ground track by the legs on both sides. It is structurally composed of a mast, a trolley operating mechanism, a crane trolley and electrical parts. Some gantry cranes have outriggers on one side, and the other side is supported by a factory or trestle, which is called a semi-gantry crane. The gantry crane consists of the upper bridge (including the main beam and the end beam), the outriggers, and the lower beam. In order to expand the working range of the crane, the main beam can extend beyond the legs to one or both sides to form a cantilever. A crane trolley with a boom can also be used to expand the crane's operating range by tilting and rotating the boom.
Rail mounted gantry cranes are specialized machinery for loading, unloading, handling and stacking operations in container freight yards, mainly applicable to ports, wharfs, railway freight yards, warehouses, and yards. The rail container gantry crane has a large span and more stacking layers, which can make full use of the site area. Rail-type container gantry cranes have strong positioning capabilities and are relatively easy to implement fully automated loading and unloading. They are an ideal machine for automated container yards. Compared with tire-type gantry cranes, they have a simple structure, good stability, easy operation and safety, and it is easy to realize single machine automatic control. Rail-type container gantry cranes can "stack 4 through 5" or "stack 5 through 6" between two rails and outreach distances, stacking 8 to 15 rows of containers. When moving on the track, the action is accurate and there are few accidents.
Electric overhead travelling (eot) crane mainly includes three major operating mechanisms: a lifting operating mechanism, a trolley operating mechanism, and a trolley operating mechanism. The hoisting mechanism is mainly composed of electric hoist, wire rope, pulley, hook or spreader. The metal structure of the electric single-girder bridge crane is mainly composed of a main beam and an end beam. The main beam structure is mostly a combined section of I-beam and steel plate, which is composed of a cover plate, a web and an I-beam, and there are longitudinal and short reinforcing ribs in the box. Its safety and reliability directly affect the operating quality and working ability of the crane.
The European-style crane is a mid-to-high-end overhead gantry crane. It is new model, adopts advanced European crane technology, compact structure, light weight, energy saving, low noise and other characteristics. There is no concept of the European-style crane in technical terms. It is a summary of domestic crane users (originated from Soviet design and manufacturing technology). Domestic cranes are reliable, versatile, and inexpensive. The requirements for overhead gantry cranes based on China's use characteristics are a clear market demand and a new definition of high-end overhead gantry cranes.
Under Slung Overhead Travelling Crane Dotrum Underslung Cranes (also referred to as Underhung or Under-running cranes) are suitable for factories, aerospace or warehouses as they do not obstruct or take up floor space. They can be either Single-Girder or Double-Girder, and are typically more suited for limited space with lighter capacities - typically a maximum of 10 ton. As both ends of the girder are mounted onto the bottom of the end carriages in an 'Up-side' position, this design eliminates the need for vertical columns to support the runway. Due to this, the Underslung Crane can ensure a more spacious floor space. Without a doubt, Dotrum Underslung Cranes are considered an essential method to enhance the maximum usage of the limited space available.
