1. LDA overhead crane

LDA overhead crane utilized for medium to heavy fabrication.. These overhead cranes are ideally suited to low buildings, where a high hook lift height is required.

The top running configuration is best used in cases where the end user has issues with headroom. The most space efficient configuration is the double girder, top running crane system.

Lifting capacity: 0.25-20ton

Span length: 7.5-32mtrs

Lifting height: 6-30mtrs

Working duty: Class C or D

Power: AC 3Ph 380V 50Hz or according to client's requirement

Control mode: Cabin control/remote control/control panel with pendant line

2. LDA overhead crane structure

Metal schemes

The main beam is made of U steel rolled by steel plate, and welded with flange beams to form a box design. The end beams are made by the same technique and material as the main beam. In case of heavier load or larger span, the end beams and main beam will be made of welding U shape groove. The main and end beams are connected by intensive bolts for convenient transportation and assembling.
Electric hoist 

The LDA overhead crane of YT adopts CD or MD type hoist. CD type has single

speed while MD type has dual speed to satisfy accurate operation.
The travel unit

This LDA overhead crane is driven in two separate ways. The cone shape braking motor or solid rotary motor (with magnetic brake) is the driving part. While the transmission part is “ open-close” gear, and the close gears are LDA or LDH gear box.
Electric devices

The motors are cone-shape cages ZDY, or YSE solid rotary ones. These two types have different electric control system. The hoist and the crane are protected by safety devices, such as lifting limit switch, terminal limit switch, over load limit, wrong phase and over current protection etc.
