ActivRAC® 3M with Pallet Rack

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.
