Rail-Top Mount:
Rail shall be 4140 steel bar 4-1/2” (114mm) wide x 3/8”
(9.5mm) high, with black zinc finish. Rail edges shall be
beveled down to a maximum of 3/16” (4.8mm) to allow for
the rail to be transversed by material handling equipment.
Rail shall disperse the wheel point loads to structural slab.
Rail shall have two permanently mounted floor anchors
maximum 15” (381mm) on center. Rails shall be installed
on top of concrete slab. Rail and carriage design allows
concrete slab to be unlevel at the following maximum
variations:
– 3/16” (4.8mm) maximum variation over any 2’ (.6m)
rail run.
– 1/4” (6.4mm) maximum variation over any 10’
(3.04m) rail run.
– 1/4” (6.4mm) maximum variation between adjacent
rails.
Rail-Recessed Mount:
Rail shall be 4140 steel bar 4” (101.6mm) wide x 3/8”
(9.5mm) high, with black zinc finish. Rail shall disperse
the wheel point loads to structural slab. Rail shall have
two permanently mounted floor anchors maximum 15”
(381mm) on center. Rail shall be installed recessed into
concrete slab and flush to top of concrete slab. Rail and
carriage design allows concrete slab to be unlevel at the
following maximum variations:
– 3/16” (4.8mm) maximum variation over any 2’ (.6m)
rail run.
– 1/4” (6.4mm) maximum variation over any 10’
(3.04m) rail run.
– 1/4” (6.4mm) maximum variation between adjacent
rails.
Mobile Carriage Bases:
Assembled structural steel carriage base will have a
minumum capacity of 7,000 lbs. (3,175 kg) per carriage
section. Each wheel assembly shall be equipped with two
steel wheels, minimum 5” (127mm) diameter steel wheels.
Wheels are equipped with two permanently lubricated
and shielded radial ball bearings. Wheel capacity 3,500
lbs. (1,587 kg) each. Wheels have solid steel axles of
1” in (25mm) 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 5.084” (129mm) high, 10-gauge
(3.4mm). 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 5” (127 mm) diameter. All wheels
on one side of the carriage shall be driven by a continuous
steel drive shaft 1-5/16” (33 mm) O.D. x1” (25mm) I.D.
connected to the 1” (25 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.
Patent Pending.
