4 Ton Overhead Crane With Hook

Specification

Description

· Introduction     

　　Weihua 4 Ton Overhead Crane With Hook is designed and manufactured according to advanced FEM/DIN standard. Weihua 4 Ton Overhead Crane With Hook has compact structure with small wheel pressure, which efficiently uses limited space in workshops to reduce structure investment.

　　· Weihua 4 Ton Overhead Crane With Hook is mainly used in various indoor workshops. According to the utilization level and load status, it is divided into two working levels: A5 and A6.

　　· The entrance direction of the driver's cab platform is divided into three types: side entrance, end entrance and top entrance.

　　· The driver's cab can be installed on the left or right end.

　　· The trolley can be electrically conductive with a safety busbar or angle steel, either on the opposite side of the driver's cab or on the same side of the driver's cab.

　　· All the actions and operations of the crane are completed in the driver's cab.
 

·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 conductor rails.

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 condutor rails 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
