Single Girder Overhead Crane Electric Overhead Travelling (EOT) cranes are designed and tailor made to suit any condition and site of application. The cranes are designed and manufactured strictly in accordance to National Standard considering adequate factor of safety and complying with appropriate duty of classifications. The capacity for the crane according to requirement can range from 500 Kg to 20000 Kg and the crane span spread from 7.5 Meter to 28.5 Meter. Any other requirement beyond this range can be discussed and designed to suit.
Under Slung 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.
Hoist double-beam bridge crane has the advantages of compact dimensions, low building headroom, light weight, and low wheel pressure. This product is mainly applicable to the transfer, assembly, maintenance and loading or unloading operations of mechanical processing workshops, auxiliary workshops of metallurgical plants, warehouses, stockyards, and power stations. It can also replace ordinary double-beam bridge cranes for production workshops in the light textile industry and the food industry. The work type is light and intermediate, and the working environment temperature is -20-40 ° C. It is prohibited to use in flammable, explosive, and corrosive medium environments. Our company mainly produces hoist double-girder bridge cranes with rated lifting capacity below 63 tons.
Cost-effective and space-saving, Dotrum semi gantry cranes provide an alternative solution for customers whose machineries are required to be positioned along the sides of the factory layout. With one leg moving on the floor rails and the other running on the runway beam, this is a very suitable design for wide factories. The operator will only require 2 operational bays without having the need to incur a high cost to build a continuous runway beam and columns in the centre of the factory. Applicable in all types of industries, Dotrum semi gantry cranes are mainly designed based on the different factory layouts and end user's production flow requirements. As a result, these cranes are available in workshops and yard industries.
It is mainly composed of mast (main beam, support legs, lower cross beam, etc.), lifting mechanism, running mechanism, and electronic control part. It uses an electric hoist as a lifting mechanism, and travels along the main beam bottom flange. The truss has a light weight and strong wind resistance.
