Description
LH type electric double-girder overhead traveling crane: The LH type 3 - 32t cranes with a span of 7.5 - 31.5m produced by our company. The main lifting device is a seated type hoist. Compared with the same type of QD electric double-girder overhead traveling crane, it has the characteristics of light weight and low cost, and is suitable for low-height workshops where the QD type is not suitable for installation.
QD type electric double-girder overhead traveling crane: The electric double-girder crane is composed of four parts: the bridge, the trolley, the traveling mechanism of the large vehicle, and the electrical equipment. This product is suitable for workshops, freight yards and warehouses in departments such as stations, ports, industrial and mining enterprises, etc., and is used for lifting, transporting and loading and unloading various materials within the fixed span.
According to different environments and different uses, it is divided into many forms such as slow speed, explosion-proof, insulation, electromagnetic, grab bucket, double trolley, dual-purpose, and triple-purpose. Our company produces various double-girder overhead traveling cranes.
Energy-saving (European-style) crane: The energy-saving (European-style) crane has the characteristics of light dead weight, compact structure and low energy consumption. A trolley and a lifting mechanism, trolley traveling mechanism and large vehicle traveling mechanism are set on the bridge to realize the handling of materials and objects in three-dimensional space. With a unique design concept, it has the characteristics of small size, light weight and small wheel pressure.

Components
-
Electric Trolley
Hoist trolley usually installed on the heavy duty bridge crane or gantry crane as a lifting mechanism. It has a simple structure and light weight. It’s mainly used in general hoisting, loading and unloading operations in machinery manufacturing workshops, warehouses, assembly and hydro-power station maintenance.
-
Main beam
The main beam is the crane's main load-bearing component, and the running track for the electric hoist. It is a triangular beam is weld by a support frame(welded by angle steel and other section steel) and an I-beam. The two sides of the span are designed with saddles connected to the outriggers, and there are rectangular steel plate connecting flanges. There are buffers at both ends of the main beam to ensure the safe operation of the trolley on the main beam.
-
Crane Hook
Crane hook is the most common type of spreader in lifting machinery. The crane hook is often suspended on the wire rope of the hoisting mechanism with the help of pulleys and other components. The crane hook should conform to the manufacturer's suggestions and must not be overloaded.
-
Crane Cab
The crane cab is the workplace of the crane operator and it undertakes a crucial role. The design of the cab fully considers the comfort and safety of the operator. It has a good view so that the operator can clearly observe the surrounding environment and operating conditions.
-
Control model
Can use control handle with pendant line, wireless remote control, or cabin control.
