Columbia produces many types of suspension systems with a full range of load capacities. Current axle capacities range from 40,000 to 870,000 pounds and each is designed and built to meet our customer's specific needs.

We offer mechanical suspension systems that range from 80,000 to 500,000 pounds. Mechanical suspensions include trunnion axle beams and walking beam suspension systems. We also offer hydraulic suspension systems from 80,000 to 300,000 pounds.

• 40,000 – 100,000 Pound Dead Axles
• Available through our subsidiary, K-B Axle who carries a comprehensive line of off-road axles and parts.
• 150,000 – 870,000 Pound Drive/Dead Axles
• In this range, the suspensions typically consist of a custom designed axle and hub assembly that can include a hydraulic lift cylinder type suspension.

Lift Cylinder Suspensions
Columbia's wheel systems incorporate hydraulic cylinders to lift the module. Once the rig is moved into position, it is lowered onto its base. Our lift cylinder designs have been constantly improved and updated throughout our 30 years in the industry.

Steering Systems
Moving a multi-million pound drilling module during the arctic winter requires a lot of experience and know-how. Whether the rig is moving from well head to well head or pad to pad, steering is a critical consideration of design.

Columbia offers several steering options, from simple, manually controlled systems to computer controlled Temposonic steering, which is employed to coordinate the movement of multiple axles. Columbia also engineers systems with the ability to turn wheel systems 90 degrees so that a rig can be moved into position along a row of wells.
