SPECIFICATIONS LoRiser 42PMF60-24 TWO POST MODULAR INGROUND LIFT SYSTEM TOTAL CAPACITY 60,000 lbs. (Axle Engaging, Front Post 42” Moveable, Rear Post Fixed) PART 1 – GENERAL 1.1 DESCRIPTION A. This Section sets forth the requirement for purchase of an in-ground axle lift to permit raising vehicles off the floor for tire service and brake work. Equipment shall be new and furnished with all specified materials for installation when delivered. Reconditioned or used equipment will not be accepted. Equipment shall comply with all applicable federal, state, and local safety regulations and codes. B. Complete lift assembly shall consist of one control console, two individual hydraulic lifting units installed in line with the longitudinal axis of the vehicle, each lifting cylinder so equipped as to engage the axle or suspension of the lifting vehicle. One of the two lifting cylinder assemblies will be moveable along this same axis to allow variable spacing between the lifting cylinder assemblies. The front moveable unit will herein after be referred to as the “front Post” and the stationary unit will be called the “rear post”. 1.2 QUALLITY ASSURANCE A. The lift installer shall be certified as a factory authorized installer, trained and authorized by the same manufacturer supplying the lift equipment. The installation shall be supervised by factory engineering staff. B. Lift manufacturer shall comply with all applicable requirements of the Buy American Act . C. Lift manufacturer must provide three (3) references on like product installations including location, address, contact and phone number. 1.3 WARRANTY A. Lifts shall be warranted to be manufactured from sound materials in a workman like manner and guaranteed against failure due to defective materials and workmanship for a period of one year. B. All parts shall be readily available locally in the United States. 1 PART 2 – PRODUCTS 2.1 TWO POST IN-GROUND LIFT : A. CONSTRUCTION FEATURES: 1. Each lifting unit shall be contained in a channel steel / sheet metal steel containment vault. Steel channels shall be welded to the exterior of the vault at the top and base to provide support when tying vault into concrete floor. The operation of the lift shall be electro hydraulic. 2. FRONT LIFTING UNIT: a. The front post (carriage and vault): The front lifting unit shall consist of a lift vault with moveable carriage which supports the front post. The front post shall be a single fixed hydraulic lift cylinder with a 24” stroke and a lifting capacity of 30,000 lbs. An anti-rotation leg will be provided on the lift unit to prevent rotation of the lift cylinder. The carriage shall be equipped with maintenance-free wheels rolling in structural channel tracks located in the front lift vault. The tops of the channel tracks will be essentially flush with the floor surface. b. Cover plates shall move with the carriage so as to keep the trench opening covered at all times. Cover plates will be of sufficient strength to support a wheel loading of one quarter of the of the design capacity without permanent deformation. c. The front and rear lift vaults shall be spaced to best match the various wheelbases of the vehicles in the fleet. The front post shall be moveable forward and rearward inside the vault to provide a 42” adjustment for proper engagement with vehicles ranging in wheel bases from ______ minimum to ______ maximum. d. When fully lowered the front adapter assembly shall not extend more than 6” above the floor and shall not drag on the floor when post is moved forward or rearward. e. Lift Locks: The hydraulic cylinder shall have an automatic hydraulic locking valve that will actuate at any position when the lift is not in motion. This locking valve shall automatically prevent the lift from lowering unless the ‘down’ button is engaged and the power unit powers the lift down. 3. REAR LIFT UNIT: a. Rear vault: Each lifting unit shall be contained in a channel steel / sheet metal steel containment vault. Steel channels shall be at the top and base of the vault to provide support when tying vault into existing or new concrete floor. Top of containment vault shall be covered with two "clam shell" style doors that provide automatic opening and closing of the containment vault when lift is raised / lowered. Manual doors are provided instead of the automatic doors when special adapters are required for specific vehicles. The top of the lift unit will be positioned level with the shop floor so that no trip hazard is present. b. Rear lift cylinder: The rear vault shall contain a single fixed hydraulic cylinder with a 24” stroke and a 30,000 lb. lifting capacity. c. Lift locks: The hydraulic cylinder shall have an automatic hydraulic locking valve 2 that will actuate at any position when the lift is not in motion. This locking valve shall automatically prevent the lift from lowering unless the ‘down’ button is engaged and the power unit powers the lift down. 4. CONTROLS: The lift console control will alternately lift the front or rear of the vehicle without turning the vehicle around. The control console shall be completely enclosed and painted. It shall be a 12 gauge (minimum) sheet metal enclosure. It shall have a steel separation panel separating the control section (top of console) from the power / hydraulic section (lower section) of the control console. It shall be free standing with anchor holes provided for floor mounting. Console shall be 18” wide X 16” deep X 46” high providing a comfortable work level for operator. a. Instrumentation shall include: system on/off switch, green illuminated button (indicating system is powered), a selector switch for “front” or “rear” lift assembly and two push buttons to “raise” or “lower” the selected hydraulic lift. b. The lift power unit shall be located inside the control console and will be powered by a 3 HP, 220 volt, 1 phase, 60 hz electric motor direct coupled to a two-stage hydraulic pump. The hydraulic pump automatically provides for fast movement of the lift in “no load” condition, and a slower controlled movement when lift is engaged with a vehicle’s axle. Motor control voltage is 120 volt. An AAL motor starter shall be included. The motor shall be energized only in the raise/lower mode of operation. c. A wired remote pendant control shall be provided which will allow the lift operator to raise or lower each lift post anywhere along the length of the vehicle. d. The lift power unit shall be connected by required lengths of stainless steel hydraulic pipe or steel reinforced hydraulic hose to each containment vault. e. Sufficient lengths of hydraulic hose with fittings shall be supplied with the lift to permit locating the control console up to 50 feet from connections on the lift unit. f. Hydraulic hoses shall be installed in 3” diameter PVC or metal conduit running thorough or beneath the floor of the work bay and sealed where conduit enters the containment vault through provided knock-outs. All plumbing components shall be supplied by the installing contractor. 5. SADDLE AND ADAPTERS: Both front and rear lift unit lifts shall include a saddle and adapters designed to properly engage and lift most heavy trucks. PART 3 – EXECUTION 3.1 DESCRIPTIVE DATA: a. Complete information regarding structural tying of vault in customer location shall be shown in manufacturer’s equipment foundation requirements. When required, company field personnel will be made available for instruction and consultation. b. Installing contractor shall provide all materials required for complete installation as indicated on manufacturer’s installation drawings. 3
