INSTALLATION INSTRUCTIONS –UNI

Review this entire page before installing the Uni-Tilt.

Consult the factory in the event there are any questions or problems at the time of installation, or for

information regarding optional features not covered by the owner’s manual.

•Modifications or additions to the Uni-Tilt without prior manufacturer’s authorization may void the unit’s warranty.

The addition of ancillary equipment to the platform may necessitate that its load capacity be reduced.

•The installation must be made so that it complies with all the regulations applicable to the machine and its

location. The end-user must verify that the supplied equipment is installed so it will be suited to the environment

in which it will be used.

•Installation must be performed by suitably trained personnel with access to the appropriate equipment. The

electrical aspects of the installation should be performed by an electrician.

---------------------------------------------------------------------------------------

For a typical installation you will need the following:

1. A fork truck or hoisting means to unload the Uni-Tilt from the freight truck and set it into place.

2. A smooth, level, and adequately strong concrete surface on which to mount and operate the Uni-Tilt.

3. Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s

architect or facility engineer to determine the best size and type of hardware with which to anchor the machine to

the floor.

•Portable units do not need to be anchored to the floor.

4. A power supply circuit and electrical disconnect matching the motor voltage and current requirements. Refer to

the machine’s dataplate, to the labels on the control enclosure, and to the electrical section in this manual for

more information. The end-user is responsible for supplying the branch circuit’s required ground fault and short-

circuit protection. (Motor overload protection is provided by a thermostat built into the motor.)

---------------------------------------

1. Move the tilter into place with a fork truck having at least a 2,000 lb capacity.

2. Temporarily connect the power supply to the pigtail cord supplied with the Uni-tilt, and raise the platform so the

unit’s safety maintenance prop(s) can be utilized. Lower the platform so the unit is supported by the prop(s).

oThe maintenance prop(s) is located in the Uni-tilt’s frame next to the lifting assembly. It is a rod with a 90° bend.

To install the prop(s), raise the platform to its full raised height and insert the longer end through the holes in the

frame roller weldment. Lower the frame roller assembly unit it rests on the prop.

oIf the platform must be raised without first having the proper power supply connected, raise the platform at the

side of the table opposite the platform cradle. Use rigging or insert a lift truck’s forks under the front edge of the

platform to tilt the platform up. Hold the frame down at the ends of the shipping 4 x 4’s on the hinged side of the

Uni-tilt while the platform is raised.

3. Anchor the frame to the floor through the holes located at the frame’s corners. (Non-portable units only.)

4. Make permanent connection to the power supply, using an appropriate wiring method.

5. Operate the Uni-Tilt through several full raise and lower cycles. Verify that the upper travel limit switch functions

properly.

6. Check the hydraulic oil level. It should be filled to within 1” to 1½” of the reservoir’s fill hole. If oil is needed,

use an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F (ISO 32 at 40°C) or a non-synthetic

automatic transmission fluid.

7. Clean up any debris or spilled oil, and verify that all of the warning and safety labels are intact.

OPERATION INSTRUCTIONS –UNI

oConsult ANSI MH29.2 - 2000, Safety Requirements for Industrial Tilters, Section 12, for the owner’s / user’s

responsibilities regarding the operation, care, and maintenance of this machine.

oEnsure that all employees involved in the operation of this machine understand and follow these instructions!

The standard model UNI (stationary) and UNI-P (portable) is suitable for use indoors in most industrial locations and

many commercial locations. It is intended to be used to lift and tilt stable, non-hazardous loads and containers having

a size or footprint approximately the same size as the platform.

Loading:

The load rating, in pounds, is shown on the machine dataplate located on the right front corner of the loading

(opposite the backstop) side of the platform . It indicates the net capacity of the machine, with a static load that is

centered and evenly distributed on the platform and having a vertical center of gravity not more than 20” above the

platform surface.

For applications involving side loading or loads with higher centers of gravity, consult the manufacturer.

The standard design Uni-Tilt is intended to be loaded with a fork truck or similar material handling equipment.

Always center the load, and place it up against the back cradle of the platform to prevent sudden load shifting when

the platform is tilted.

Do not exceed a rate of two feet per second when moving loads onto the platform.

Note: The addition of any ancillary equipment to the platform by third parties must be taken into account when

determining the maximum working load to be placed on the platform.

Warning: Do not exceed the Uni-tilt’s load ratings. Injury to personnel or permanent damage to the structure could

result from exceeding the listed capacity.

Operation:

Warning: Keep all personnel clear of the machine when it is in operation. Be certain no part of any person or object is

under any part of the platform before lowering the unit.

Caution: Always carefully watch the container and any load in it when it is in operation.

To raise or tilt the platform back toward the operator, press the “UP” pushbutton.

To lower or tilt the platform toward the floor, press the “DN” pushbutton.

When a pushbutton is not being pressed, the unit will hold its position wherever it is in its travel range.

The Uni-tilt can be operated in either one of two movement sequences.

•Sequence #1:

•Starting with the platform in the fully lowered position, press and hold the “UP” pushbutton while you push the

sequence selector pedal in against the frame of the table with your foot. After about five seconds, the pedal can

be released.

•The platform will tilt back toward the operator until it reaches a tilt angle of 40° to the floor. It then will lift

vertically until the bottom of the cradle reaches a height of 16½” above the floor.

•To lower the platform, press and hold the “DN” pushbutton. The platform will drop vertically until the bottom of

the cradle is about 12” above the floor, and then the platform will tilt down away from the operator until it is

again fully collapsed and level with the floor.

•Sequence #2:

•Again starting with the platform in the fully lowered position, press and hold the “UP” pushbutton. (Do not press

the sequence selector pedal.) The platform will rise and tilt back at the same time, until it reaches a height of 19”

from the floor to the bottom of the cradle and a tilt angle of 35°.

•To return to the fully collapsed position, press and hold the “DN” pushbutton. The platform will both lower and

tilt down towards the floor concurrently until the unit is again fully collapsed and level with the floor.

On DC-powered units, attempting to raise the lift when the battery is low will cause the motor relay protection to

prevent the motor’s operation. Adequate battery voltage is indicated by a green LED on the motor relay. See the next

page for more notes regarding operation of battery-powered units.

Ensure that all safety and warning labels stay in place and are legible. Refer to the labels page in this manual.

ADDITIONAL INSTRUCTIONS FOR BATTERY-POWERED UNITS

Warning!

!Working with or near lead acid batteries is dangerous. Batteries contain sulfuric acid and produce explosive gases.

A battery explosion could result in loss of eyesight or serious burns.

!Do not smoke or allow a spark or flame near batteries. Charge batteries in locations that are clean, dry, and well

ventilated. Do not lay tools or anything metallic on top of any battery. All repairs to a battery must be made by

experienced and qualified personnel.

!When working with batteries, remove personal items such as rings, bracelets, necklaces, and watches. Batteries

can produce enough energy to weld jewelry to metal, causing a severe burn.

!Always have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

!Operating the battery with a low battery voltage can cause premature motor contact failure.

!Do not expose the lift or charger to rain or adverse conditions.

!Replace defective cords or wires immediately.

!Check the battery’s water level frequently.

Battery Charger Operating Instructions

Never operate the charger with either of the cables coiled. Operating a battery charger with the cord either coiled

or wrapped around itself could cause the cord to overheat, melt, and cause a short-circuit or a fire.

Connection: the ribbed wire of the charger’s output cord must be connected to the battery’s negative (-) terminal.

The non-ribbed wire (with words printed on it) must be connected to the battery’s positive (+) terminal.

When properly connected, the charger will indicate the status of charger output:

Flashing green LED – the charger is not seeing a good connection to the battery.

Solid yellow LED – the charger is providing charging current to the battery.

Solid green LED – the charger is maintaining a fully charged battery.

Plug the charger into a standard 115V receptacle. If an extension cord must be used, keep it as short as possible.

Caution: Remember to unplug the charger before moving the equipment. Failure to do so could cause damage to

cords, receptacles, and other equipment.

The battery charger can be left connected to the battery indefinitely without risk of harming the battery.

Troubleshooting:

If the unit does not operate, check all of the wiring connections to make sure they’re both mechanically and

electrically sound – specifically at the battery, the motor, and at any location a wire is connected to the chassis.

Also, make sure the quick-connect plug on the end of the pendant control cord is plugged in correctly (if

applicable).

A fully charged lead acid battery in good condition at room temperature should read 12.65 volts. At 11.9 volts it is

considered to be fully discharged and in need of charging. When checking battery voltage, wait at least 1/2 hour

after the charger has been turned off before checking the battery’s voltage.

If the batteries don’t seem to be taking a charge, check the charger’s 115V supply circuit and the charger’s output

with a voltmeter. If all check okay, confirm the battery’s state of charge using a hydrometer or a voltmeter.
