•Please read and understand this manual prior to installation or operation of this lift. Failure to do so could lead to

property damage and/or serious personal injury.

•Do not modify lift. Autoquip cannot foresee and is not responsible for injury or damage which results from

unauthorized modifications or misuse of lift.

•Never run the unit with the gates or doors open! Do not operate unit with doors open or with the interlocks

“defeated” (bypassed)!

•Shaft way door barrier bars are not intended to be used as a primary means of personnel protection. It is the

responsibility of the operator to ensure that all gate/door interlocks have been installed and are functioning

properly. Serious injury or death could result if upper level gates/doors can be opened when the lift is not

present at that level.

•To protect against death or serious injury, all labels must be on lift and must be legible.

•If any of these labels are missing or cannot be read, contact Autoquip for replacement labels (see 1.1 Contact

Information).

•Do not weld on the guide flanges of the masts! Interfering with the free travel of the wheel guides could cause

permanent damage to the lift and prevent safety devices from operating as intended.

•Spilled hydraulic fluid is slippery and may also present a fire hazard. Clean up spilled hydraulic fluid.

•Use properly rated hoses only! Never use fittings or hoses that are not properly rated for the intended use.

•Do not over travel! Mechanical stops must be in place to prevent the platform from over traveling. Over-

traveling can cause permanent damage to the platform or failure of the lifting cylinders.

•Never operate the lift by “manual-ing” the electrical controls (using the contactors located inside the control

panel). All safety devices are by-passed in this mode of operation and lift damage or severe personal injury

could occur.

•Ensure one “WARNING – Do Not Tamper” label is adjacent to (within 6-12 inches) each sensing device (limit

switches, door status switches, door interlocks, etc.) in a location that is visible to the operator.

•GUARDS, INTERLOCKS, SAFETY DEVICES and ELECTRICAL CIRCUIT must be restored to correct

operation when installing parts or making adjustments or repairs.

•Failure to relieve operating system pressure could result in the sudden and unexpected release of high-pressure

fluids during maintenance and/or repair of the lift which may result in severe injury or death. Assume that all

hydraulic hoses and components are pressurized.

•Wear personal protective equipment, such as gloves and safety glasses, whenever installing, servicing, or

checking a hydraulic system.

•Never try to stop or check for a hydraulic leak with any part of your body; use a piece of cardboard to check for

hydraulic leaks.

•Small hydraulic hose leaks are extremely dangerous, and can inject hydraulic oil under the skin even through

gloves. Infection and gangrene are possible when hydraulic oil penetrates the skin. See a doctor immediately to

prevent loss of limb or death.

•Ingesting hydraulic fluid is toxic and hazardous to people and wildlife. Symptoms may be skin irritation,

weakness in the hands, intestinal bleeding, pneumonia, or death. Seek first aid immediately. Dispose of spilled

fluids appropriately.

•No riders! The VRC is provided for the sole purpose of transporting goods between floor elevations. At no time

should it be used to transport personnel.

•Before operating VRC, all personnel interacting with lift must read, understand and follow instructions and safety

warnings in this manual.

•Close all gates when not in use. Never leave the VRC unattended with gates left open.

•Do not use a swivel fitting between velocity fuse and cylinder. If installed improperly, it will not lock up in the

event of a hydraulic line failure.

•Velocity fuse is not repairable. Replace velocity fuse if defective.

iWARNING

6 800.811.9876

•Never use concrete anchor bolts on a cinderblock or brick wall! The wall will not withstand the pull force

developed by the lift. Use only recommended anchoring and bracing methods illustrated in this manual.

Equipment damage or personal injury could result.

•The pressure switch is not functional with temporary power! The power unit will continue to run as long as the

contact button is pressed. Permanent damage to the lift may result if power to the electric motor is not shut off

once the platform makes contact with the stop bolts.

•Purge air in the system! The presence of air in the system can lead to a lock-up of the velocity fuses. (Air reacts

like a spring when it is compressed.)

•Do not operate the VRC until the platform is leveled and the guide beams are plumbed and secure.

•Take extreme caution when running the unit before mechanical stops are installed and adjusted properly! Lift

over-travel can cause severe damage

•Do not operate motor at relief pressure! The motor should not be operated for more than a few seconds when

the unit is operating at relief pressure. Longer running times could result in damage to the pump.

•Do not operate motor without cover reinstalled on relief valve.

•Do not operate the VRC until all sensing switches have been confirmed to be installed and adjusted correctly.

•Do not use Teflon tape. Tape fragments can cause malfunctioning of the hydraulic system. Loctite PST #567

pipe thread sealant or equivalent is recommended.

•The control panel instructions are in the controller manual sent with the order. These are required for

installation.

•The “Bill of Lading” will state the number of pieces shipped. TWO ITEMS MAY BE BANDED TOGETHER AND

COUNT AS ONE PIECE.

•Autoquip recommends replacing any NPT fittings that have been disassembled due to their inherent design for

sealing.

•Use approved fluids only. Use of unauthorized fluids may cause damage to seals and hosing.

•Always find out why the E-Stop button may have been pressed, and be sure to correct the problem

(malfunction, interference, etc.) before making the lift operational again.

•In order for the lift to operate:

oAll gates/doors guarding the lift must be closed.

oLoads cannot hang over the edge or sides of the platform.

oThe load must be within the specified load capacity of the lift.

oAll electrical safeties, sensors, and switches must be in their “normal” condition.

•Per ASME B20.1, operator pushbutton stations must be located such that they cannot be activated while

standing on the platform.

•Make sure the top cylinder rod bolt is re-installed.

3.2 Safety Features

There are several active safety features and devices to help protect personnel, property, and the

equipment.

Zero Drift Feature

A zero-drift feature has been incorporated into the VRC. The zero drift uses a limit switch mounted at the

upper level and the pressure switch circuit. The limit switch is tripped closed when the platform is at the

upper level. The electrical circuit energizes if the pressure switch closes due to a pressure drop or leak.

The motor will start and build pressure until the pressure switch shuts the motor off. This keeps the

platform from drifting downward from the upper level. When the operator closes all gates and energizes

the down pushbutton, the zero drift circuit is disabled and the platform will lower.

Hydraulic Velocity Fuses

Each hydraulic cylinder has a hydraulic velocity fuse (HVF) installed in the cylinder port. These HVFs are

installed at a predetermined flow velocity as the oil returns to the reservoir. They do not affect incoming oil.

Should a catastrophic rupture or breach occur in the hydraulic system, and oil flows through the breach

that exceeds the HVF rating, the HVF will trigger and lock up. This lock up will occur within one to two

inches of downward movement of the platform.

NOTE: Air in the system will also cause a lock up. Air acts like a spring when compressed. To remove

air from the system, (see 7.3.4 Bleeding Air from System).

NOTE: Small fitting leaks will not trigger the HVFs. In an air-free system, the breach must be large

enough to cause an uncontrolled or destructive lowering speed. Should a triggering and lockup occur, it

can only be released by applying upward hydraulic flow in a functional system.

Safety Release Bypass Valve (SRBV)

The SRBV is a part of the hydraulic system. Should the system pressure exceed the predetermined

pressure setting, the SRBV will bypass the pump output back to the oil reservoir. The SRBV is factory set

to the proper pressure, which will prevent damage to the mechanical, hydraulic, and electrical systems due

to overloading, obstruction, or other circumstances. This setting should be tested once installation is

complete (see Installation section).

Power Supply Secondary Circuit Breaker

This circuit breaker is down stream of the power supply and protects the 24 volt DC control circuit from

damage should a fault occur which would result in excessive electric current flow. Should the circuit

breaker trip it will prevent operation and the interlock circuit will not operate. These circuit breakers are

located in the control enclosure.

Motor Overload Relays (MOR)

These are current sensing devices that are located in line with the three legs of the electric motor primary

power circuit (208, 230, or 460 volt). They protect the motor from excessive current draw and overheating

if it becomes overloaded or has a short circuit. Should an over-current situation be detected on any leg

the MOR will trip and open the path to ground for the contactor coil via an auxiliary contact.
