SYSTEM DESCRIPTION

J. General: The system consists of four-post shelving units mounted on manufacturer’s track-guided carriages to form a compact storage system. System design permits access to any single aisle by moving units until the desired aisle is opened. The carriage/rail system provides uniform carriage movement along the total length of travel, even with unbalanced loads.

K. Carriage System Design and Features: The carriage system consists of a formed structural steel frame with hardened steel riding on steel rails recessed mounted to the floor. Rails shall be types selected by the manufacturer to ensure smooth operation and self-centering of mobile storage units during travel without end play or binding. Rail types, quantities and spacing shall be selected by the manufacturer to suit installation conditions and requirements. All bearings used in the drive mechanism shall be permanently shielded and lubricated.

L. Movement Controls: Provide a carriage control panel on the accessible

(open) end of each moveable carriage, located 44 inches (1118 MM) above the base, centered on the face panel. Minimum controls shall include directional control buttons/icons, STOP/RESET push-button/icon and a red reset light/icon.

1. System controls shall start motors on each movable carriage

“sequentially” to minimize power demands and shall provide dynamic braking to provide smooth operation. No additional hardware shall be required to change between “sequential” and

“block” movement. Maximum running speed shall be limited to 3.3 inches (84 mm) per second.

2. Provide solid state controls and indicator lights/icons for a visual indication of safety system operation. Provide each aisle with a programmable distance sensor to ensure proper timing for start/stop operation.

3. Pushing the directional control button/icon on any moveable carriage adjacent to the desired aisle location in the direction away from the desired aisle location opens the system at the desired aisle. The selected aisle shall open automatically regardless of the position of the carriages. Automatic Reset: The carriage control heads will display a constant green light, or green arrow icon, at all carriages indicating that the system is ready for the next aisle access. Provide for automatic reset if system is equipped with optional Zero Force Sensor (ZFS) system safety feature, or other redundant safeties.

4. Controls shall feature safety activated message and direction indicator designating which aisle safety was activated or back lit message indicating which aisle is in use (i.e. “Right Aisle in use” or “Left Aisle in use”).

5. Provide Bluetooth control via the TUSC Mobile Control App in replace of or in addition to the standard powered control or touch technology system controls.

10 56 26.23 - 3

M. Drive System: The system shall be designed with a positive type motorized drive which minimizes end play and that carriages will stop without drifting. All system components shall be selected to ensure a smooth, even movement along the entire carriage length.

1. Each electric carriage shall be provided with a current limited fractional horsepower gear motor, connected to drive wheel assembly with a roller chain.

2. System shall include a chain sprocket drive system to ensure that carriages move uniformly along the total length of travel, even with unbalanced loads.

3. A tensioning device shall be provided on each chain drive (when applicable).

4. All bearings used in the drive mechanism shall be permanently shielded and lubricated.

5. System shall operate on 115 V.A.C. 50/60 hertz, 20 amp dedicated circuit provided by others, one per module.

6. Overhead mounted power pantograph distribution system shall conceal all interconnecting wiring.

N. Safety Features:

1. Visual indicators shall provide verification that carriages are in the locked or unlocked mode.

2. Dual full-length infrared photoelectric safety sweeps shall be provided to stop carriage movement if the sweep contacts an obstruction while in motion. Sweep must be equipped with red/white stripped safety demarcation tape with text, “PLACE FOOT

HERE TO STOP”.

3. Entire system shall be C-UL US system listed.

4. An infrared photoelectric aisle entry sensor system shall be provided to stop carriage movement if the system detects persons entering a closing aisle.

5. A handheld rechargeable power pack shall be provided for emergency operations in case of primary power failure.

O. Finishes:
