The forklift adapter kit shall include all equipment and components required to lift forklifts equipped with pneumatic or cushion type tires. D. RAL colors shall be high visibility manufacturer’s standard colors with reflective tape or paint. II. Technical Performance Requirements. A. Lift system: shall be a hydraulic or recirculating ball screw systems. 1. Mobile column lifts shall perform without movement pulsations, jerks, or unsteady lifting. If additional brakes or components are required to prevent movement the Offeror shall include items with their offer if required. 2. Column lift systems shall be able to perform without becoming contaminated by dust, debris, or fluids. The Offeror shall include any protective shrouds or devices to prevent contamination with their offer, if required. 3. Mobile column lifts shall be relatively maintenance free and easy to maintain and operate. 4.

In the event the Offeror’s product is of poor workman ship or design and is not made for heavy commercial and industrial use, the City may reject Offeror prior to award. 5. Lift systems shall be approved and certified to ANSI/ALI ALCTV-current Standard for Construction of Automotive Lifts by an independent, third-party Nationally Recognized Testing Laboratory (NRTL) who is authorized to conduct testing by the Automotive Lift Institute (ALI) and recognized by the Occupational Safety & Health Administration (OSHA). Proof of certifications must be submitted upon request and posted on each lift. ETL/Intertek is an OSHA recognized NRTL. B. Lifting capacity: Each column shall have a nominal rated capacity of sixteen thousand (16,000 lbs.) pounds or greater. C. Dimensions: Achieved lifting height of the column shall be no less than seventy inches (70”) when measured from the foundation on which the column rests to the bottom of the lifting fork. The column height shall not be greater than one hundred inches (100”) when fully lowered. D. Lifting time: The lifting time shall take no longer than eighty (80) seconds from the ground to its fully extended height. E. Motor power: Manufacturer’s standard providing the optimal capacity to meet the performance and durability requirements of the specification. F. Flexibility: The columns shall be flexible and capable of being positioned effortlessly around the vehicle. Set-up shall be capable of increasing from two (2) expanding up to a possible eight (8) columns without any adjusting of the columns. G. On board batteries power source: Every column shall be equipped with manufacturer’s standard battery(ies) with a charger. Fully charged batteries shall have a minimum of fifteen (15) lifting/lowering cycles at 100% of lifting capacity. Batteries shall be capable of being recharged using a one hundred ten (110) volt power supply. H. User friendly operation: Selector buttons shall be provided on every column and/or a remote control for individual, paired, and synchronized operation. I. Control panel: The various functions of the mobile lifting system shall be initiated from the control panels on the columns and/or a remote control. Each control device shall have the minimum control functions: 1. Buttons to control UP, DOWN, LOCK RELEASE, SPEED CONTROL, EMERGENCY STOP. 2. Lock to prevent unauthorized or unintended operation. 3. LED’s or a display to illustrate battery charge level, column height, column selection and pairing, column height, load weight and speed operation as well as fault condition. All control panels shall have automatic synchronization through the full stroke of the hydraulic cylinder. Electrical system component housing shall have an IP65 rating or higher. J. Safety device: An independent and fail-safe mechanical locking system shall be provided on each column. The safety device shall be completely independent from the lift system. A locking pawl and ratchet system shall be used to ensure at all times, proper and automatic locking at any height. The locking notches shall be integrated into the lift carriage. The lock pawl shall be mounted to the inside of the column and function as a wedge between the column and lift carriage. The mechanical safety lock shall be automatically engaged at all, times when the lift is not operating. K. Pallet jack mechanism: Shall have a gas shock, hydraulic jack, or spring-loaded mechanism incorporated into its design. The primary purpose of the pallet jack shall be to serve as a safety mechanism to ensure that the mobile column is not lifting while the parallel jack is extended. If the operator fails to lower the jack after the column is positioned, as soon as the column experiences a load during a lifting cycle, the jack will retract to lower the column to its foundation for stable lifting. The secondary purpose shall be to dampen the impact of the floor imperfections experienced while the column is relocated. The third purpose is to allow the lifting columns to be easily moved.
