Product Description

FEM Standard Open gear wheel block for gantry crane

Product Description

General description

Wheel block as one part for the End carriage,which is easy for connecting and transportation, have advantage that for customer's stock. And NANTE have Modular design for Wheel block which save the delivery time to provide the customers best products and service.
Wheel block mainly composed by wheel, motor, steel structures, bearing, shaft, buffer, connecting plate and so on. 
The large selection of travel wheels and special wheel designs enable wheel block  to be adapted to almost any travel rails and operating conditions. Cost-effective, ready to install, simple installation and alignment, favorable dimensions and a wide variety of versatile connection options make our wheel block particularly cost-effective. As crane wheel block is requested according to different needs from client all over the world, we can make it by following drawings and customized processing from custom.

Open gear Wheel block  is a type of wheel block  which the driving by Soft start motor and have Self-lubricating bearing for no-maintenance, it is more economical than the European standard wheel block.


Design Feature

1. Using steel plate for housing. Wheel material is alloy steel with proper heat treatment which is more stable and durable.
2. The compact structure, convenient installation and maintenance, exquisite appearance and light weight. Use Q355B steel material(ISO EN S355, DIN ST52, ASTM A 572 Grade 50), welding specification follows ISO 15614, AWS D14.1, deflection can from 1/700 ~ 1/1000, MT or PT is requested for Fillet welding and UT is requested for joint welding.
3. Shoot Blasting follow ISO8501-1 SA2.5 class, roughness follow ISO 8503 G class, clearness follow 8502-3 Level II. Use top brand like Hempel, International, and Jordon's Rich zinc epoxy painting for the prime, middle layer coating. Use polyurethane topcoat for the finished layer coating. All NANTE painters are trained or inspected by NACE or FROSIO level II Inspector.
4. Soft start Gear motor makes sure the quality, IP54, F insulation class, and equipped with electro-magnetic brake, the brand can be NANTE Motor from inland China and other motor from TAIWAI.
5. The control panel enclosure is IP55, and wiring is base on IEC standard. User inverter control for lifting and cross travel, smooth and low energy consumption. And PLC programming is optional.
6. Can customized design base on different application and duty group.

Product Application
