ActivRAC® 3M with 4-Post

Spacesaver’s ActivRAC® 3M High-Density Mobile Storage System puts your storage on wheels and rail to maximize storage efficiency, allowing you to recover valuable floor space or double your storage capacity in the same space. ActivRAC 3M’s durable, steel carriages are built in the USA and pair seamlessly with Spacesaver’s reconfigurable 4-Post shelving, mobilizing up to 3,000 pounds per carriage section. ActivRAC 3M and 4-Post shelving combined provide you with a versatile, efficient storage solution, that can be customized to fit any space or functionality.

  • Mobile Carriage Bases
    Assembled structural steel carriage base will have a
    maximum capacity of 3,000 lbs. (1,360 kg) per carriage
    section. Each wheel assembly shall be equipped with two
    steel wheels, minimum 3” (76mm) diameter steel wheels.
    Wheels are equipped with two permanently lubricated
    and shielded radial ball bearings. Wheel capacity 1,500
    lbs. (680 kg) each. Wheels have solid steel axles of
    0.75”(19mm) diameter. Wheels shall be dual flange,
    all-wheel guided. All carriage sections between wheel
    assemblies have integral diagonal bracing to maintain
    accepted tolerances for function of systems. Side profiles
    shall provide and maintain wheel assembly alignment
    and squareness. These profiles shall be pre-drilled at the
    factory, but are bolted, and assembled on the job site as
    integral carriage members. Structural steel side profiles
    shall be minimum 3.00” (76mm) high, 12-gauge (2.7mm).
    Finish shall be powder-coat paint.

    Line Shaft Drive System
    Line shaft drive consists of a wheel section positioned at
    each rail location. Wheel section shall consist of a load
    wheel and a drive wheel. Each wheel shall be provided
    with two permanently shielded bearing assemblies.
    Wheels shall be ASTM A 536 specification 65/45/12
    machined ductile iron. All wheels shall be 3” (76 mm)
    diameter. All wheels on one side of the carriage shall be
    driven by a continuous steel drive shaft 1” (25 mm) O.D.
    x 0.810” (20.5mm) I.D. connected to the 0.75” (19 mm)
    diameter wheel drive axles with bolted clamp connections.

    Mechanical Assist Housing and Operator
    Mobilized storage bases are moved by means of a
    mechanical assist chain and sprocket drive unit and
    operator located in the front of each carriage. Multiple
    drive ratios are available. A roller chain connects sprockets
    and adjustable chain idlers and is required to maintain
    proper chain tension. Carriage is moved by rotating a three
    spoke handle with rotating knobs. The anti-roll mechanism
    system is required to prevent carriage from drifting. Dual
    control housings and operators for accessing a system
    module from both the front and rear are optional.
    Specifications are subject to change.
