3.3.5. Safety Devices: Each lift shall be equipped with safety devices that meet or exceed the requirements for safety devices in ANSI B 153.1, including the following:
220.127.116.11. An oil control device shall be provided with each air-oil tank to prevent hoisting operation if the oil level is low.
18.104.22.168. A mechanical leg, with an automatic locking mechanism, shall be provided with each cylinder assembly to hold the lifting structure in the fully extended position at rated load. This mechanical leg shall be capable of holding the superstructure at the fully extended position without permanent distortion of the components.
3.4. Options: The following become a part of the bid when specified by the ordering agency in the Invitation for Bids:
3.4.1. Air cooler or refrigerator for air system in addition to water traps and drain plugs.
3.4.2. Air-oil tank installed below ground.
3.4.3. Excavation for lift (when installed by vendor or his agent). (See Paragraph 12.)
3.4.4. Fiberglass sleeves or coating for cylinder assemblies.
3.4.5. Other: (For example: Recessed trench, or cathodic galvanic shield systems).
4. WARRANTY: Lifts furnished under this specification shall be fully guaranteed against defective material and workmanship for a period of one (1) year from the date of installation. Any lift furnished which fails to meet or exceed all conditions and requirements of this specification shall be modified or replaced at the vendor's expense to conform with these specifications.
5. CURRENCY OF MODELS: Products delivered under this specification shall be produced in the current year, unless otherwise specified in the Invitation for Bids.
6. TESTING: Testing shall be done by or at the direction of the Commission and/or the ordering State agency. Test shall be performed on products after delivery and installation. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the testing shall be borne by the supplier. The products furnished under the specification shall be tested by the following methods or approved equally applicable procedures:
6.1. Lifting Capacity: With air pressure maintained at a minimum 150 psig, determine the loading capacity by securely loading the superstructure of the lift with the minimum rated capacity (8,000 pounds). Distribute this load evenly (2,000 pounds at the end of each arm). Raise the load to its maximum height and measure the time from the opening of the oil control valve until the automatic non-rotation leg locks the lift at the extended position. Failure of the lift to raise the rated capacity load with 100 seconds constitutes failure of the lift (See Paragraph 3.2.).
Measure the plunger travel and the floor-to-vehicle contact point. Compare with the requirements of Paragraph 3.2.3.
Lower the lift and measure the time required for a point on the lift (or automobile) to travel a measured distance. For example, measure the time required for the lowest point on a tire to travel from the fully extended position to contact with the floor. Accurately calculate this speed by dividing the distance traveled by the time. Compare with the requirements of Paragraph 3.2.
Raise the load a second time and release the oil control lever at approximately the midpoint of lift travel to test the proper operation of the automatic cutoff switch. After a period of at least five (5) seconds, continue rasing the lift to its fully extended position. Lower the lift and again observe the operations of the automatic cutoff switch. After a period of at least five (5) seconds, lower the lift. Failure of the lift to hold the rated capacity load in both of the above positions for a least five (5) seconds constitutes failure of the lift.
Repeat the above procedures for the other superstructure. Determine compliance with the various requirements as above.
6.2. Safety Control: Drain the oil supply to a level less than three inches (3") or 10% of the capacity, whichever is smaller. Attempt to raise the hoist. Failure of the safety device to prevent the raising of the hoist constitutes failure of the lift.
7. PACKAGING: Lifts shall be packaged in accordance with the best recognized commercial practices in a manner readily acceptable by common carriers engaged in interstate commerce.
8. MARKING AND LABELING:
8.1. Marking: Each shipping container or shipping document shall be clearly marked with the following data:
8.1.1. Name of contents.
8.1.3. Order or contract number.
8.1.4. Name and address of ordering agency.
8.1.5. Agency requisition number.
8.1.6. Manufacturer's name and address.
8.2. Labeling: Each lift shall bear, in a conspicuous place, a securely affixed and durable label showing the following:
8.2.1. Manufacturer's name.
8.2.2. Model number.
8.2.3. Serial number.
8.2.4. Rated capacity.
