High-Duty Components for Smooth Crane Travel and Maximum Uptime

Whether you’re building an bridge crane or gantry crane, your system is only as strong as its travel gear.

CMAK’s end truck carriages, wheel blocks, and travel systems are engineered to handle high duty cycles, heavy loads, and extreme industrial conditions — ensuring smooth movement, reduced maintenance, and long-term reliability.

Why Choose CMAK Travel Systems?

  • Effortless Installation – Modular design with socket connections means faster setup for crane installers
  • Reliable Performance – Direct-drive systems reduce mechanical complexity and improve durability
  • Low Maintenance – Lifetime-lubricated bearings and rugged construction minimize downtime
  • Precision Engineered – Designed in compliance with FEM standards for top-tier industrial performance
  • Direct Drive Trolleys – No gears or belts to maintain
  • Standard 2-Speed Travel with Frequency Inverters – Ideal for precision and smooth acceleration
  • F-Class Insulation & IP55 Protection – Safe, dust and moisture resistant
  • GGG70 Graphite Cast Iron Wheels – Strong, wear-resistant, built for demanding tracks
  • Compact Wheel Blocks – Up to Ø400 mm diameter for tight spaces
  • Wide Wheel Range – From Ø125 mm to Ø710 mm, suitable for all types of heavy-duty operations
  • Natural Rubber Buffers – Shock-absorbing protection during travel
  • Top-Running & Under-Running Compatibility – Works across different crane systems
  • Multiple Mounting Plate Options – Side, top, or combo mounting for flexible design integration

CMAK equips its travel wheels with SKF brand 21000, 22000, and 23000 series bearings, offering superior load capacity and durability compared to the 6000 series bearings commonly used by competitors.

  • Handles Lateral Loads – Unlike standard 6000 series bearings, CMAK’s bearings are specifically engineered to withstand lateral forces, ensuring safe, stable crane travel even under side stresses.
  • Heavy-Duty Design – Available with 45 HRC surface hardness for extreme wear resistance.
  • Flexible Mounting Options – Torque-arm or flanged connection configurations available for seamless integration.

This design choice means longer service life, fewer failures, and greater reliability — especially in high-capacity bridge and gantry crane applications where side forces are inevitable.

These components are the backbone of crane travel mechanisms in:

  • Bridge cranes
  • Gantry cranes
  • Warehouse crane systems
  • Ceiling cranes & underslung cranes
  • Container handling systems
  • Factory floor cranes
  • Electric wire rope hoists
  • Electric chain hoists
  • Manual hoists and trolleys
  • Single girder or double girder cranes
  • Custom crane builds
