Product description
The LH type electric hoist bridge crane includes end beams and a main beam. Both ends of the main beam are equipped with gears, and the axes of the two gears are both connected to the main beam through a sleeve. Both sides of the main beam have grooves, and the middle part of the main beam is connected with a crane through the grooves. The sides of the two end beams are provided with tooth grooves, and the top of the two end beams are inserted with worm gears. The top of the worm gear is provided with a worm, and the bottom of the worm gear is provided with a second motor. The bottom of the two end beams is provided with a first motor, and one side of one of the end beams is embedded with a master control switch. This utility model controls the operation of the first motor by controlling the master control switch to make the main beam rise, and the second motor operates to help lock the main beam. The installation process only requires ground control, which is convenient and simple to operate, and greatly reduces the risk of high-altitude operations, improving the safety factor.

Structure
The double girder electric hoist overhead crane is consisted with double girder bridge mechanism, traveling mechanism, trolley with frame and electrical parts and The lifting mechanism is equipped with CD/MD electric hoist with frame. Compared to single girder overhead crane, its structure is stronger, more secure use, so double girder overhead crane lifting capacity is larger.
Application
LH-Double Girder Electric Overhead Crane is bridge crane with hook, suitable for indoor or outdoor fixed cross inter-cropping handling and transport work. Lifting capacity range 3T-50T.
It’s widely used in machinery manufacturing, metallurgy, petroleum, petrochemical, port, railway, civil aviation, food, papermaking, construction, electronics industries, workshop, warehouse and other material handling situations which need precise positioning, large components precise assembly.
