i. Vehicle lifts including safety equipment, controls and accessories of the following types: at least 72,000 lb capacity surface mounted wheel engaging mobile column lifts.

b. QUALITY ASSURANCE

i. Lift and all components shall be new. Used or refurbished lift and components not acceptable.

2. PRODUCTS

a. 72,000 LB. CAPACITY SURFACE MOUNTED WHEEL ENGAGING MOBILE COLUMN LIFTS

i. Lift Characteristics:

1. The intent of this specification is to establish the minimum standards of quality and performance for portable mobile column lifts which will be used to lift a variety of vehicles including Trucks, Buses, Passenger Vehicles, Fork Lifts and other general service vehicles. This specification shall describe a mobile column surface mounted, wheel engaging lifting system designed to elevate vehicles for the purpose of inspection and maintenance. One Lifting System shall consist of four electric-hydraulic mobile columns sustaining 72,000 lb (32659 kgs) capacities (18,000 lbs (8165 kgs) per mobile column). Mobile columns may be added, (not exceeding 8 columns), removed, or changed out. All mobile columns shall operate synchronously from any one of the lifting units by means of a control interface. The control system shall have replaceable printed circuit boards equipped with quick-connect electrical couplers. The mobile columns shall be battery operated with a DC charging system built into each column for easy recharge and communication cable cord reel for cable management.

ii. Mobile Columns: 18,000 lbs. per column.

1. 30 foot buses – 4 columns

2. 48 foot buses – 6 columns

iii. Lifting Fork Length: 14 inches forks accommodate rim sizes 9 inches (229 mm) minimum to 24.5 inches maximum.

iv. Rise: 70 inches

v. Fabrication:

1. Column Assemblies:

a. Columns shall be constructed of formed channel fabrication from a single steel plate and shall not require welded seams to form the column structure.

b. Rigid column design shall be protected from corrosion via sand blasted enamel painting of metal surfaces.

c. Each column shall be fabricated to a set of legs that will sit directly on the floor and provide a stable platform when lifting a load. When unloaded the mobile columns ride on a set of wheels to allow the units to be moved. When a vehicle is lifted, the wheels shall automatically retract and the lift shall sit down flat on its steel base and no lifted weight shall remain on the casters. Legs have an extended fork configuration that allows for extensions to be added at any time. Such extensions will permit the addition of longer forks to lift dual wheel assemblies or optional assemblies for lifting vehicles further away form the column assembly.

d. Each of the lifting units shall contain a mechanical locking latch mechanism completely separate from the drive of lifting system.

2. Hydraulic System:

a. Each lifting unit shall be equipped with an electric hydraulic power unit, consisting of a DC motor, gear pump, reservoir, check valve, pressure relief valve, and two control valves. Entire power unit totally enclosed to protect from dirt and water.

b. The direct drive lifting cylinder shall be installed in such a manner as to push the carriage up, using no chains or cables. The extension of the cylinder shall occur inside of the carriage as to keep the plunger of the cylinder protected from dirt, sand, or any possible mechanical damage.

c. Hydraulic check valve shall hold load at any position of the cylinder. Redundant mechanical safety lock shall be continuously engaged except while lift is being lowered.

d. Pressure relief valve shall prevent overloading of the lifting unit.

e. Unit shall be equipped with two control valves that shall be used to maintain synchronous operation when a lifting system of more than one column is being commanded to raise or lower.

f. Hydraulic system is self-lubricating and shall require little to no maintenance.

g. A velocity fuse shall be installed directly to the end of the cylinder in order to keep hydraulic fluids from discharging if there is a fast leak somewhere after the cylinder, which could cause the load to unintentionally be lowered.

3. Control System: Premium, wireless system.

a. All mobile columns shall have identical control panels and shall be designed to be interchangeable without regard to master/slave relationships.

b. All mobile columns shall have a manual lowering override due to lose of power to the unit.

c. Indication lights on each control panel shall show mobile column configurations for an individual mobile column, paired mobile columns, grouped mobile columns, or all mobile columns.

d. "UP" and "Down" buttons shall have momentary function "Dead Man" type switches while depressed and operate from only one control panel at a time.

e.

f. "Emergency Stop Button" on each panel will shut down all connected mobile columns.

g. All control panels have automatic synchronization through the full stoke of the hydraulic cylinder with a maximum tolerance of 1 inch.

h. Lift shall come equipped with a lower to lock function.

i. Lift shall come equipped with a slow lowering function.

j. The lift control interfaces shall include visual representations showing the relationships between the lift columns and a vehicle, such as lift column icons positioned around a vehicle icon.

k. Lift shall come equipped with a three color battery charge indicator. The charger shall also indicate the status of the battery.

l. System set up must be accomplished in a single trip set up around columns to minimize set up time and user confusion, direction and operation will not matter.

b. The MBTA will accept and review all bids. Any discrepancies from the technical specification must be noted and highlighted and returned with the bid package.
