LDA electric hoist single girder crane is composed of girder weld by steel plate and I-steel, end girder, electric hoist and traveling mechanism. The electric hoist runs along the lower flange of the I-steel of the girder to accomplish article hoisting. It features light structure and easy installation and maintenance, and is widely used for different places for hoisting such as factories, warehouses and material yards. It is prohibited to use in the environment with inflammable, explosive and corrosive media. The span is 7.5~22.5m( subject to non-standard design according to user's requirement) The classification group is A3, and the operating ambient temperature is -25~40℃.It has three operation modes: Ground handle, wireless remote control and cab. The Cab has two types: open cab and closed cab. The traveling motor can be soft start motor and variable-frequency adjustable-speed motor according to user requirement. The crane can start steadily and runs safely and reliably.
All the standards used is according to China National Standards and ISO standard.
