Overhead Crane End Carriage

Structures:​

• Frame 

  • It is a welded box structure that provides rigidity and strength.

  • It connects directly to the bridge girders.

• Wheel Assemblies

  • Include driven wheels and idler wheels that run on the runway rails.

  • High-quality alloy steel wheels with hardened tread surfaces ensure long service life.

• Drive Unit (Travel Mechanism)

  • It consists of an electric motor, gearbox, and brake.

  • Provides power for the crane’s long travel (LX movement).

• Bearing Housings and Axles

  • Support the wheels and transmit loads evenly.

• Electrical Components

  • Include limit switches, cable carriers, buffers, and safety devices for smooth, controlled operation.

Features:​

• Suitable for both single-girder and double-girder bridge cranes.

• The crane girder can be mounted and connected to the end carriage beam either by welding or high-strength bolts. Pre-drilled bolt holes are provided for convenient installation.

• Depending on the wheel load, various wheel sizes (diameters 150–500 mm) can be equipped. The wheels feature excellent wear resistance for long service life.

• The drive system uses a soft-start motor for smooth, safe, and reliable operation. A gear motor drive option is also available.
