1.0 Introduction
PURPOSE OF EQUIPMENT
The UpRight Personnel Lift is a portable lift designed to
elevate personnel and light equipment to work above
the ground.
GENERAL DESCRIPTION
There are four basic UpRight Personnel Lift models: the
UL-25, UL-32, UL-40 and the UL-48.
All models consist of a Platform, Mast and Chassis.
The UL-32, UL-40, and UL-48 are equipped with a tilt
back mechanism to facilitate passage through a standard
80 inch doorway. This tilt back mechanism is optionally
available in a configuration adapted to fit the UL-25.
Platform
The platform is an aluminum structure supported by a
steel cage support attached to the mast. It has 43.5-inch
high "clamshell" upper and lower guardrail assembly
with gas spring assist for opening and closing, six (6) inch
toeboards and integrated midrail.
Figure 1-1: UL Portable Personnel Lift
Mast
The platform is raised and lowered by a seven stage
mast assembly that is driven by a single stage hydraulic
lift cylinder and a series of leaf chains. An AC or DC
electric motor powers a hydraulic pump which in turn
energizes the cylinder. Solenoid operated valves control
the raising and lowering of the Platform.
Chassis
The Chassis is a steel structure that consists of the first
stage of the Mast Assembly, control box, battery charger
(for DC Models), and AC or DC Motor, hydraulic pump
and reservoir, 12v battery (for DC Models), a tilt baCk
assembly (standard on 32', 40', and 48' machines,
optional on 25' machines), and four Outriggers. The
chassis is equipped with outrigger status lights which
indicate that outrigger interlock switches are closed
Operator Controls
Controls consist of a Lower Emergency Stop Switch,
Upper Emergency Stop Switch, Key Switch and three (3)
push button controls: Power On, Up, Down. The
Power On button must be pushed along with the Up or
Down button to operate the machine. An Emergency
Lowering Valve is located on the power unit at the base
of the machine.

Operation
3-1
Section
UL-25/32/40/48 Portable Personnel Lifts
3.0 Introduction
GENERAL FUNCTIONING
The AC or DC electric motor directly drives a hydraulic
pump and is energized only when all four outriggers are
set, closing the outrigger limit switches, and powering
the outrigger relays.
The oil flow is normally allowed to return to the reser-
voir through the lift valve until it is energized by de-
pressing the lift button and the power button simulta-
neously with the keyswitch on and both emergency stop
buttons pulled out. Oil is then diverted to the lift
cylinder until the lift function is stopped by the operator
or until pressure in the system reaches the relief setting
and is bypassed to the reservoir through the relief valve.
When lowering, oil is allowed to flow out of the lift
cylinder through an orifice located in its base (limiting
the decent speed) and through the down valve when it
is energized by depressing the down button and the
power button simultaneously with the keyswitch on and
both emergency stop switches pulled out. In case of
powered function failure, the unit may be lowered by
turning the manual release on the down valve or by the
platform Emergency Down (Optional).
DESIGN FEATURES
The UL - Series Lifts have the following features to
ensure safe operation:
•Interlocks are provided on each outrigger socket that
prevent Platform elevation if the Outriggers are
improperly installed.
•The Power and UP or Down buttons must be
depressed for the controls to operate, preventing
inadvertent actuation of the controls.
•The Chassis and Platform Controls are equipped with
an Emergency Stop Button for stopping all powered
functions.
•An Emergency Lowering Valve is provided to lower
the Platform in the event electrical power is lost.
•Dual chain lift system for added safety.
•An Orbit Level is provided on the Chassis Base so
the machine can be properly leveled.
•Optional Emergency Down from the platform is
available in the event electrical power is lost.
3.1 Safety Rules andPrecautions
All personnel shall carefully read, understand
and follow all safety rules, operating
instructions and the Scaffold Industry
Association’s MANUAL OF RESPONSIBILI-
TIES before performing maintenance on or
operating any UpRight Aerial Work Platform.
The UL 48 model is intended for indoor use only.
Before using the UL-Series Lift:
NEVER elevate Platform unless all four (4) Outriggers
have been properly installed. All outrigger screwjack
pads must be in solid contact with a firm surface before
the Platform is elevated.
NEVER attempt to move the UpRight Lift with people or
materials on the Platform or with the Platform elevated.
NEVER operate the machine within ten feet of power
lines. THIS MACHINE IS NOT INSULATED.
NEVER sit, climb, or stand on the Platform guardrails or
midrail.
NEVER elevate Platform without first leveling the base.
NEVER use ladders, planks or other devices to increase
the height of the Platform.
NEVER attach overhanging loads to the Platform or
increase the Platform size.
NEVER elevate the Platform if it contains more than one
person or more than the rated load (see to table 1-1)
LOOK up, down and around for overhead obstructions
and electrical conductors.
NEVER change operating or safety systems.
NEVER use Outriggers from one model on another model.
CLOSE and secure the gate after entering Platform.
Verify that the locking pin is fully engaged.
INSPECT the machine thoroughly for cracked welds,
loose or missing hardware, hydraulic leaks, damaged
control or power cables and loose wire connections.
NEVER use the UpRight Lift as a freight or personnel
elevator.
NEVER recharge batteries near sparks or open flame;
batteries that are being charged emit highly explosive
hydrogen gas.
AFTER USE secure the work Platform against unautho-
rized use by turning key switch off and removing key.
NEVER replace any component or part with anything
other than original UpRight replacement parts without
the manufacturer’s consent.
NEVER use the UL48 out of doors.
