7.5 Ton LX Model Suspension Overhead Travelling Crane Single Beam
8m Span
Description of Suspension Overhead Travelling Crane
LX-type Electric Single-Girder Underslung (suspension) Crane is a
kind of light & small crane with track and usually used together
with CD1, MD1 or HC type electric hoist. Generally, the lifting
capacity is 0.5~20t, the span is 3~16m, traveling speed is 20m/min
or 30m/min. It also can be tailor made as your special
requirements.
With its advantages, such as tight structure, rigidity, flexible
operation, low noise, safety and reliability, LX Underslung
(suspension) Crane are widely used at sites like industrial and
mining company, storehouse and material yard etc.

cabin, electrical components & lifting mechanism (electric Hoist,
chain hoist or manual block)
- The main girder can be in form of I-shape, box-type or
combination structure according to different lifting capacity and
span.
- Shot-blasting Sa2.5 for complete girder after welding, stress
release
- Epoxy zinc rich high quality painting, 2x2 with 140μ M
- 10.9 class High tension bolts mounting between girder and legs
- Geared Motor Driver system or traditional LD Driver system
- Smoothly moving, effectively braking, long service life
Electrical Features
- Conductor power supply
- All hoist and crane movements are independent and can be run
simultaneously.
-The control panels are IP54
- The components are positioned in a maintenance friendly way, and
the whole layout provides with good protection
