Unless otherwise stated in the specification, all equipment and options that are normally provided as standard by the OEM shall be provided by the Vendor whether or not included in the specification below. If any specification requirement has been updated by the OEM manufacturer, Vendor or third-party equipment provider the Vendor shall identify the updated equipment and request approval under “approved equal” requirements.

All manufacturing modifications, equipment, devices, materials, warranties, miscellaneous items, etc. which the manufacturer customarily and routinely applies to the vehicle shall be included. No advantage shall be taken by the manufacturer in the omission of any part or detail, which goes to make the vehicle complete and ready for service, even though such parts or detail are not mentioned in these specifications. All equipment provided must meet or exceed State and Federal requirements applicable to the equipment. All parts not specifically mentioned which are necessary in order to provide a complete vehicle shall, at a minimum, conform in strength, quality of material and workmanship to what is provided by the automotive industry generally.

Where a name brand or other requirement is identified in the specification that is perceived by the industry to limit available competition, the Vendor may request that an “approved equal” be provided. Requests for “approved equal” shall be made to the agency prior to bid submittal in adequate time for the agency to review the request and respond within the timeframe set out for questions in the bid documents. Request for “approved equal” shall be supported by documentation, verified test results and any available information relating to product life and maintenance and repair costs in addition to documentation that product complies with all federal, state, local and industry requirements.

The Fixing America’s Surface Transportation (FAST Act) dictates domestic percentage content requirements for Buy America.

Wheelchair Lift Barrier System:

The wheelchair lift barrier system (WLBS) shall be of modular steel construction. The design shall consist of two primary subassemblies, the power side, and the receiver side. The WLBS shall consist of two coupled rotating arms, pivotally mounted to the power side. The upper arm shall be telescopic to minimize vehicle interior height requirements. The upper and lower arms shall rotate from a vertical stowed position to a horizontal deployed position. When deployed, the upper arm shall be at a height 30”-32” above vehicle floor level and the lower arm shall be at a height of 5”-7” above floor level.

Both the vertical and horizontal velocity of any portion of the WLBS arms shall be less than 12 inches per second (305 mm per second). The power supply shall be provided by the 12-volt system from the wheelchair lift. A single electric actuator shall provide the means to rotate the coupled upper and lower arms between the deployed and stowed positions. The operation of the unit shall provide a smooth and uninterrupted cycle. The noise level of the WLBS may not exceed 80 dBa as measured at any lift operator's position designated by the platform lift manufacturer.

The WLBS shall be controlled by the wheelchair lift hand control. There shall not be a secondary powered control method of the WLBS. Operation of the WLBS shall be integrated to the wheelchair lift. Deployment of the WLBS shall precede downward movement of the wheelchair lift platform from vehicle floor level. Stowing of the WLBS shall not commence until the wheelchair lift platform has traveled to and stopped at vehicle floor level. Deployment of the WLBS shall be controlled by the “Down” or “Lower” function on the wheelchair lift hand control. Stowing of the WLBS shall be controlled by the “Fold” or “Stow” function on the wheelchair lift hand control. Both WLBS stow and deploy functions shall be momentarily controlled and all movement of the wheelchair lift barrier system must cease with no input to the wheelchair lift hand control.

A manual override system shall be provided to ensure operation of the lift in case of electrical or mechanical failure of the WLBS. The manual override control shall be located inconspicuously to prevent unintended activation. When activated, the manual override control shall not impede or otherwise affect normal wheelchair lift operation.

A method for manually operating the WLBS shall be provided. Manual operation shall be prevented unless actively engaged by decoupling the actuator from the rotating arms. When manually operated, the coupled upper and lower arms shall smoothly and reliably rotate to the deployed and stowed positions. When manually operated, a secondary - mechanism shall be provided to retain the coupled arms in the vertical position. When manually operated, the WLBS shall maintain the stowed and deployed interlock signal functionality for the wheelchair lift and shall not impede or otherwise affect normal operation of the wheelchair lift.

When deployed, the upper arm shall withstand a 250 lbf load applied in an outward direction with 4” maximum deflection.
