FURNISHING AND DELIVERING ONE SET OF EIGHT (8) MOBILE COLUMN LIFTS AT ELLISON ONIZUKA KONA INTERNATIONAL AIRPORT AT KEAHOLE, KAILUA-KONA, HAWAII

Specifications include, but are not limited to: The work consists of the Furnishing and Delivery of a Setof eight (8) 148,000 lbs. capacity mobile column lifts, 24 volts DC, control boxon every column, adjustable forks. The vehicle weight classification shall notrequire the operator to possess aU.S. Department of transportation (DOT) Commercial Driver License (COL).;a. A lifting system or set (consisting of up to 32 columns) forvehicles shall be composed of interchangeable columns. The size ofthe set shall be able to be configured by the operator at time ofset up without the need to modify the operating system. It shallbe possible to operate up to 480 columns within any facility.With a set of up to 32 columns, it shall be possible to operateany single column, a pair of columns, or all columns together, atthe same time.;b. Each column shall contain its own power supply which consists oftwo deep cycle (group 31) 12 VDC batteries combined to provide astable 24 VDC power supply.;c. The main power shall be fused between the primary power switchand the motor/control circuits to protect against overload.;d. When fully charged, the on-board battery power system shall becapable of 19 lifting/lowering cycles at 100% of liftingcapacity and 28 lifting/lowering cycles at 50% of liftingcapacity.;e. The 24 VDC on board power supply shall incorporate a built-inrecharging system with a pictograph on the display so the operatorcan visually verify charging status.;i. The recharging system shall be a built in 110 VAC batterychargers with indicator lamps. The battery charger shall beenclosed within a steel cabinet for protection from damage.The charger indicator lamp shall be easily visible through asight glass mounted externally in the control cabinet. Theindicator lamp shall be illuminated steady red when the systemis recharging, green when batteries are fully recharged, andflashing green when the charger is providing a tricklecharge. It shall be possible to operate the lifting columnwhile the battery charger is actively charging the batteries.;f. The base frame of the lifting column shall be of arectangular design. The contact pattern to the foundationunder the column shall be triangular in design to ensureuniform contact with the lifting foundation.;2. Lifting Capacity:a. Each individual column shall have a nominal rated capacity of18,500 lbs. (8,500 kg).;3. Dimensions:a. The achieved lifting height of the column shall be no less than73 inches (1,854 mm) when measured from the foundation onwhich the column rests to the top of the lifting fork.;b. Column height shall not be greater than 97 inches (2,464 mm)when fully lowered and 143.S inches (3,645 mm) when thecarriage has achieved maximum height.;c. Column lifting fork shall be 14 inches in length.;4. Tire Size:a. Wheel contact forks shall be adjustable by hand and freelyaccept tires with rim diameters between RlO and R22.S. Theadjustable forks shall incorporate a mechanical locking deviceto ensure the fork cannot relocate/adjust during use.;5. Pallet Jack Mechanism:a. The pallet jack mechanism shall have a gas shock incorporatedinto its design which shall serve two purposes. The primarypurpose of the pallet jack gas shock shall be to serve as asafety mechanism to ensure that the mobile column is notlifting, while the pallet jack is extended. If the operatorfails to lower the pallet jack after column positioning, assoon as the column experiences load during a lifting cycle, thegas shock will retract to lower the column to its foundationfor stable lifting. The second purpose of the pallet jack gasshock shall be to dampen the impact of floor imperfectionsexperienced while the column is relocated.
