Brief Description
The LDA type top running single girder bridge crane is an improved bridge crane designed on the basis of the LD type. It employs CD/MD type electric hoist as its lifting mechanism which runs at the I-steel under the girder. This overhead traveling crane is widely used for lifting heavy goods in factories and warehouses.
YUNTIAN is a major hoisting machinery manufacturer in China. This single girder bridge crane that we produce with top running hoist trolley can start steadily and run safely and reliably. It features more reasonable structure and superior steel with higher toughness. The most obvious characteristic of this lifting equipment is its ingenious structure and the convenience for maintenance.
The operator should bear in mind that this heavy lift crane is prohibited to be used in combustible, explosive and corrosive environments. It comes with three operation modes, i.e. ground control, wireless remote control and cab operation. The cab is available in two patterns: open type and closed type. They can be installed on left or right side of the bridge crane according to practical situation.
Ambient Temperature Conditions
1. The power supply of this single girder bridge crane should be three-phase AC power supply (380V/50Hz).
2. The working environment temperature of this top running bridge crane is -25~ 40 Celsius degree.
3. Relative humidity is no more than 50% when the temperature is 40 Celsius degree.
