AC49000A ISO Container Casters

TYPE OF WHEEL: Urethane on Iron


CAPACITY (per caster assembly): 16,800 LBS

FINISH: Top Casterloc assembly is galvanized, bottom caster assembly is painted.

CALULATED WEIGHT (per caster/per set): 292.25 LBS / 1,169 LBS

MAXIMUM OPERATION SPEED: 5 MPH Operating these casters in excess of this speed can cause failure.

Tandemloc Container Casters are designed to rigidly clamp to ISO 1161 Corner fittings which are commonly found on intermodal freight containers, customized container shelters, and other specially built items.

Once installed, these container casters provide an efficient way of mobilizing containers at low speeds. NOTE: These casters are for NON-HIGHWAY USE ONLY. Common applications that require container mobilizing include container relocation for facility maintenance, alterations, upfits, or creating and loading shelters.

We also offer towbars to be used in conjunction with our container casters that fit the end holes of the bottom corner fittings.

These AC49000A-6PA casters are comprised of polyurethane on iron wheels, swivel locking turntables that lock at 90° increments, and the Tandemloc Casterloc which enables the casters to RIGIDLY connect to the ISO container.

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)).
