1.3.3Deck/Ramp:

1.3.3.1Deck and Ramp to be specified per end user.

1.3.3.2Floor covering to be determined by end user.

1.3.4.2Mechanical Floor Level Safety Sweep (Alternate):

A passive Mechanical Floor Level Safety System must be incorporated that insures in-aisle, full time user safety. A steel hinged safety bar must run the full length to the bottom and on both sides of each movable carriage flush with the bottom line of each range frame. WHEN THE SWEEP IS ACTIVATED, AN INTERNAL DEVICE SHALL INTERLOCK WITH THE DRIVE TRAIN RESULTING IN A POSITIVE STOP. This device must be completely mechanical in design and not utilize AC/DC electrical current in any form. The passive safety sweep shall automatically reset upon de-activation.

1.3.4.2Auto Aisle Lock Safety System (Alternate)

The Auto Aisle Lock Safety System prevents movement of the two ranges bordering an open aisle automatically. When a handle is turned to open aisle the system engages. An audible “click” sound can be heard as the aisle is opening, indicating that the auto aisle lock system is activated. Assurance that the aisle lock system is active is also provided visually by use of the Safety Status Indicators located on the front of system above the control switches. These indicators indicate green when a range is free to move in the direction of the indicator and orange when the range cannot be moved in the direction of the indicator.

After an aisle is opened, the range to either side of the aisle automatically locks preventing

the aisle being closed. When another aisle selection is needed, it is necessary to manually

reset the automatic aisle lock on both sides of the aisle by lifting upward on the control

switches on either side of the aisle. When the locks are reset, the safety status indicators

will once again indicate green and the aisle is no longer secure.

1.3.5Carriage/Drive/Guide:

1.3.5.1Carriage: All modular carriage frames shall be a minimum 11 gauge steel "U" channel design to insure rigidity of the system. Only steel carriage frames shall be considered and must be no less than 5" high x 1-3/4" wide. Optional 11 gauge shelving cross-bracing members can be installed at no interval greater than 48" center to center. The steel carriage frames shall be painted with quality powder coat paint. The overall carriage height with wheels shall not exceed 5-1/2". Stationary carriages at the end of the system shall be of the same construction and height as movable carriages and must be anchored to the tracks.

1.3.5.2Carriage Load: The standard load capacity of any carriage shall be a minimum of 1,000 lbs. per linear foot.

1.3.5.3Drive Train - Double Flanged Wheels: True 5" dia. (measured bearing surface to bearing

surface not including flange) drive wheels located on one side of the carriage shall be

connected by a full length coupled tubular drive shaft. The dimensions of the drive shaft

must have at least an outside dimension of 1.125", with an inside dimension of .885", with a wall thickness of at least .120". All wheels on one side of the carriage shall be drive wheels. Double flanged wheels shall act as a guiding system. All additional wheels shall be of the same specifications of the 5" double flanged wheels. Each wheel shall be mounted on a .750" diameter solid steel shaft, which is supported by permanently lubricated, self-aligning sealed ball-bearing pillow blocks. Systems utilizing a chain driven system mounted on the drive track or systems not requiring all tracks driven, twist and rack and are, therefore, unacceptable. The connection between the drive shaft and the wheel shaft shall be by two (2) steel spring pins placed at 90 degree angles at each end of the drive shaft to insure the elimination of any play. Coupling type devices shall not be allowed and are not acceptable. Ranges less than 18" in depth shall use wheels not less than 3-5/8" dia.

1.3.5.3Drive Train - Center Flanged Wheels (Alternate): True 5" dia. (measured bearing surface

to bearing surface not including flange) drive wheels located on one side of the carriage shall

be connected by a full length coupled tubular drive shaft. The dimensions of the drive shaft

must have at least an outside dimension of 1.125", with an inside dimension of .885", with a

wall thickness of at least .120". All wheels on one side of the carriage shall be drive wheels.

Center flanged wheels shall act as a guiding system (minimum two (2) tracks per carriage).

All additional wheels shall be of the same specifications of the 5" center flanged wheels.

Each wheel shall be mounted on a .750" diameter solid steel shaft, which is supported by

permanently lubricated, self-aligning sealed ball-bearing pillow blocks. Systems utilizing a

chain driven system mounted on the drive track or systems not requiring all tracks driven,

twist and rack and are, therefore, unacceptable. The connection between the drive shaft

and the wheel shaft shall be by two (2) spring steel roll pins placed at 90 degree angles at

each end of the drive shaft to insure the elimination of any play. Coupling set-screw type

devices shall not be allowed and are not acceptable. Ranges less than 18" in depth shall

use wheels not less than 3-5/8" dia.

1.3.5.4Operation: The handle is turned in the direction of the desired range movement. A sprocket on inboard end transmits the motion via a chain to a sprocket on the axle on one side of the undercarriage. The axle is common to all wheels on that side, and therefore, functions as drive wheels. This system must be designed so that the following gear ratios are available as options: 1:2,000, 1:3,000, 1:4,000, 1:6,000, 1:8,000 and 1:10,000.

1.3.5.5Optional - Dual Latch Release.

The dual latch release allows system operators to lock and/or unlock the aisle lock

mechanism on units with controls at both ends. The dual latch release is attached to both

front and rear drive mechanisms by means of a linkage system that travels through the

carriage under the shelving. Releases that travel through the shelving are unacceptable.

1.3.6Operating Handles:

1.3.6.1Handles: The system must be designed for interchangeability of handles. The handle shall be a single crank, 3-prong, or a collapsible / disengaging single handle.

1.4END FRAMES

1.4.1The end frame must be constructed of no less than 18 gauge cold rolled steel of commercial quality and painted with powder coat paint. The end frame shall be a structural component to insure the integrity of the shelving mount between the carriage and the end frame. The shelving must be attached to the end frame at the top, the middle and the bottom of the end frame to insure stability of the shelving and integrity of the mount to the carriage. The choice of the color of the end frame is to be specified by the customer from factory standard paint colors. High pressure laminate must be available as an option.
