NLH Double Girder Overhead Crane with Hoist

Product Introduction

Description：

Modular and Compact Design

1. The crane main girder made of computer-optimised box sections, end carriages are made of torsionally rigid, welded box-section design. 

 

2. By using compact hoist and high strength materials, the crane has much smaller sizes, wheel load and weigh.

 

3. Compact structure, low clearance, small dimension and large work scope, improving production efficiency.

 

Advanced Manufacturing Technology

1. Advanced steel plate pretreatment production line for shot blasting, painting and drying.  

2. The crane main girder, end carriages and trolley frame adopts our robot automatic welding technology.

 

3. The industry leading crane bridge frame and trolley frame processing technology after welding.

 

4. The industry leading automatic spraying production line includes three workshops of sandblasting, painting and drying. 

 

High Safety, Reliability, Efficiency and Maintenance Free

 1. Germany ABM Hoist lifting motor double-winding squirrel-cage pole-changing dual speed hoisting motor with stable and reliable operation, and free of maintenance.

 

2. Safety customed monitoring systems for hoisting and travelling mechanism.

 

3. The crane provides with many protection including linkage, overload protection, zero protection and limit protection, ensuring the crane always under safety operation.

 

4. The crane provides with advanced PLC automatic detection function.

 

5. The Crane Standard working duty is FEM 2M/ISO M5, equipped with our ND or NR series electric rope hoist with 1,600 hours of service at full load.

 

6. Standard dual speed for hoisting and variable frequency drive (VFD) control speed for cross and long travelling.

 

7. Electric Components. Electrical components uses ABB, Siemens and Schneider international brands.

Features

Optional Functions

 

1. Anti-collision Protection

 

For several cranes travelling on the same rail, the common resolutions refer to install contact anti-collision device to avoid sharp impact due to incorrect operation. Non-contact infrared sensor anti-collision device will be additionally installed to take double safety protection measures with sound and light alarm if running busily or under an important working environment.

 

2. Tandem Operation

 

Loads can be safely transported by two ND(S) rope hoists through one single control unit, two cranes systems with up to four rope hoists can be synchronized as well.

 

3. Smart Electronic Anti-sway Control Technology

 

The electronic anti-sway control technology can reduce the mechanical and electrical damage caused by load shaking through controlling the sloshing of the load. The crane becomes easy to control, and the loads can be easily and accurately reached the designated position.
