AC49000A Shipping Container Casters

Move containers using our reliable rigid clamp connection with our urethane on iron and pneumatic container caster options.

Tandemloc Shipping Container Casters rigidly clamp to ISO 1161 Corner Fittings, commonly found on Intermodal Freight Containers and many Military Shelters, generator set-ups, and communication vans. The rigid clamp connection is one of the features that make our Container Casters the most reliable on the market today.

Many designs offer a typical twistlock connection that is not clamped tight. In fact, it is a loose connection, allowing the wheel to bind and scuff along, causing damage to the wheel or floor. Others tighten, but only modestly and the result is the same. If you value your container and its contents, you will appreciate the rock-solid clamped tight connection and overall ruggedness of this product.

Once installed, they provide an efficient way of mobilizing at low speeds (non-highway use). The common uses are moving containers in and out of a facility for maintenance, alterations, upfits, or for complexing and loading shelters. Towbars are also available and these fit the end hole of the corner fitting.

The Container Casters are very rugged products, available in a wide range of capacities and wheel types for different surfaces. The pneumatic casters are recommended for uneven surfaces or when floor damage is a concern. All casters are swivel type with a swivel lock, locking at 90° increments. This offers the user the most flexibility by allowing all to swivel for tight turns or to lock two (rear) if desired when towing.


  • FINISH: Top Casterloc is galvanized, bottom caster is painted.
  • CALCULATED WEIGHT: See chart below.

Installing into standard ISO containers with ISO 1161 corner fittings at corners
  • Lift container per international standard (ISO) 3874 or other means so that the bottom surface of the corner fittings are about 40" above the rolling surface.
  • With a fork lift truck raise the unlocked Casterloc into the bottom hole of each corner fitting & activate the twist lock with its handle. Before lowering the container, adjust the clamping stud to tighten connection ( 50 to 125 ft/ lb.) Notice - tightening must be done before lowering.
  • When all four Casterlocs are tight, lower the container to the level rolling surface.
  • The container may be raised a second time & retightened to the same torque after "settling", if desired.
  • Moving standard freight containers on casters differs from moving containers on a chassis because the caster connection has less horizontal structural strength. For this reason, the speed of movement must be slower and the surface on which the caster rolls, must be reasonably smooth. Excessive forces in a horizontal direction can cause failure. For this reason, speed shall not exceed the limit shown for each caster.
  • Moving heavy containers on casters requires that its movement always be under control for direction and braking on both level and unlevel surfaces. A towing vehicle with tow bars affixed to the forward bottom corners is the optimum method of moving & braking. Personnel should remain clear of the roll path to prevent injury. Sufficient personnel should be utilized for good visibility.
Important Note
  • Lifting and handling ISO freight containers should be done by qualified personnel familiar with ISO standard 3874. This standard is available from the International Standards Organization (in the U.S.A.; American National Standards Institute (ANSI)).
