China Lb Explosion-Proof Single Girder Overhead Crane

LB Explosion-Proof Single Girder Overhead Crane

Lifting Weight 1-20t

Max Lifting Height 24m

Span 7.5-31.5m

The design, manufacture, installation and operation of LB Explosion-Proof Single Girder Overhead Crane meet the requirement of JB/T 10219 standard. This crane is equipped with
HB explosion-proof wire-rope electric hoist which is a light type equipment.

Explosion-proof grade is ExdIIBT4 or ExdIICT4 and it can be used at workshops with initiation ability lower than IIB or IIC, and danger area 1 or 2 (according to GB3836.1-2000). The explosion-proof performance of motor and all electric equipment meets the requirement of GB3836.2-2000.

Mechanisms
1. Computer optimized design of box-typed main girder, the full length of web plate is cut and formed through numerical control and its deflection is accurate.

2. Low clearance structure of trolley and reasonable size of hook allowing the crane wide application scope.

3. Arc wheels or flat wheels, anti-friction bearings, honey-typed buffers and anti-derailment devices.

4. Three-in-one motor drive, steeples speed control, hardened reducer, safety disc brake.

5. Good performance, runs smoothly with the steeples speed control

6. Shot blasting grade reaches Sa2.5 after welding and releasing internal stresses to insure the best
performance of main girder.

7. Painting epoxy zinc-rich primer, and the thickness of oil film is 140 μm.

Electric System
1. Power supply through slide lines.

2. Phase protection; automatically disconnect main power when phase stagger occurs.

3. The crane and hoist are mutually independent and could travel at the same time.

4. Sliding contact line meets the requirement of power supplying and adapts shaking.

5. Etch-proof control handle with protection degree IP54.

6. Heavy-duty aviation plug.

7. Electrical components are equipped in position that convenient to maintain, and with good protection to avoid inadvertent contact.

8. Electric cable is suspended in cable trolley which slides flexibly and smoothly on a C-type steel.

Safety Protection
1. Locked fall-proof reducer

2. Outdoor hoist with rain-cover

3. Alarm indicator lights

4. Infrared anti-collision
