Product Details and Features

Double girder bridge crane is composed of two bridge beams attached to a track, and are usually provided with overhead electrical tether-rope trolley lifts, but may also be provided with overhead electrical chain lifts depending on the application. SEVENCRANE Overhead Cranes and Hoists can provide simple single girder bridge cranes for general use, and also provide custom built double girder bridge cranes for various industries. Double girder bridge crane is also used in the interior or exterior, either on bridges or in gantry configurations, and are commonly used in mining, iron and steel manufacturing, railroad yards, and marine ports.

Application

Double girder bridge crane typically require greater clearance above the crane runway beam elevation as the lift trucks traverse over the top of the cranes bridge girder. Single-girder cranes provide better approach angles to both the hoist and the bridge trip than double-girder cranes. Although it is not commonly seen, a double girder bridge under-running crane may be provided with a top-running trolley hook. Double girder bridge cranes consist of two bridge beams attached to a track, and are usually provided with top running wire rope electrically powered trolley hoists, but may be provided with top running electrically driven chain hoists depending on the application.

Product Process

Using current computational systems, SEVENCRANE Double Girder Overhead Cranes can adjust their weight in order to minimize forces placed on the structure by their loads, while also improving lifting device stability during the loading of a larger volume of cargo. As bridge crane spans and capacities expand, wider-flanged girders will increase the required depth (girder height) and weight per foot. The basic structure of a commercial bridge-mounted overhead-traveling crane is that trucks running on wheels down the length of a track system, with a bridge-cable girder fixed on an end truck, and the boom trucks suspended the booms, which travel over the span. Overhead cranes by GH Cranes & Components are available in two styles, box-girder and standard profiles, and are equipped with a built-in lift mechanism, usually either a hoist or open-ended hoist.
