Top running crane is a lifting equipment that is placed horizontally over workshops, warehouses and yards for lifting materials. They are mounted on rails on top of the building's support structure, allowing the crane to move along the length of the building. Top running overhead crane is the most commonly used crane type which has a fixed track system installed on the top of each runway beam. The lifting capacity of top running overhead crane will not be limited and it can be manufactured to lift loads from 1 ton to 450 tons. Since the crane is supported by steel support columns or existing concrete steel building support structures, it is very suitable for moving extremely heavy loads.

The industrial rubber tyred gantry crane we sell are designed with multiple operating modes to meet customers' different working conditions. And we produce several types of spreaders for use with industrial rubber tire gantry cranes, each designed for a specific type of cargo. Some of the most common types of spreaders include: container spreaders, steel coil handling spreaders, hook spreaders, lifting beams with adjustable hooks, lifting clamps, specialty spreaders, and more.

Warehouse gantry cranes are widely used in factories, construction sites, and material handling plants to lift and transport materials. There are different types of this crane such as semi-gantry crane, single-girder gantry crane, durable double-girder gantry crane, efficient mobile crane, warehouse rail-mounted container gantry crane. Customers can choose the appropriate type according to actual needs. SEVENCRANE, a professional crane manufacturer, provides cranes with excellent performance and low prices. Choosing our company is more efficient and cost-effective.

The warehouse gantry crane produced by SEVENCRANE has an Automatic Storage and Retrieval System (ASRS), which is a warehouse stacker used for elevated shelf systems. The AS/RS lifting system uses automated technology to store and retrieve pallets. The warehouse crane system is mainly composed of three operating mechanisms: lifting mechanism, crane operating mechanism, and trolley operating mechanism.

1. The operating mechanism of the overhead traveling bridge crane cart must be equipped with brakes so that the cart can stop safely within the permitted braking range after power failure. When the sliding distance of the trolley after power failure exceeds the specified value during normal operation, the brakes should be adjusted immediately to ensure that the braking formation meets the requirements.

1. Transmission form of crane trolley operating mechanism The trolley operating mechanisms of small and medium-sized cranes all adopt the form of centralized drive, as shown in Figure 2-11(a), while the trolley operating mechanisms of large cranes usually adopt the form of separate drives.
