A INTRODUCTION

2. Product Introduction

Up-Lift UT series elevating work platforms employ advanced technology and material, powered

by a high quality hydraulic system and incorporates various safety measures to provide a higher

capacity, safe and reliable aerial working unit.

The components which make up the UT product are derived from proven quality sources, with

key components sourced from quality European suppliers. The product is equipped with a

number of advanced features. Lower height models have a patented back-up power feature

allowing lowering of the platform during power black-outs. As a consequence, operators feel a

greater sense of safety comparing with many similar products.

Up-Lift UT elevating work platforms are extensively used for cleaning, decorating, maintenance

and aerial signage work in hotels, restaurants, department stores, emporiums, shopping centers,

airport departure lounges, sports stadiums, convention centers and stadiums, as well as factories,

hospitals, universities and colleges. The smaller models are designed to pass through standard

doorways and elevator lifts and are especially suited to small confined working space

applications.

C USING THE MACHINE

5. Machine Achieving Optimal Performance

1) The standard unit is suitable for indoor operation and the operator should as far as possible

operate the machine indoors.

2) If the machine is used outdoors, care should be taken to ensure that the ground is firm and

solid to prevent instability. Avoid operation under any windy condition.

3) Always check that the outrigger position indicator lights are operating correctly.

4) Descent at full height: When the platform is loaded and raised to its highest point,

momentarily press the platform control’s “POWER” and “DOWN” buttons simultaneously.

Then fully engage these two buttons to continue the descent. This minimizes the impact to

the equipment of a change in hydraulic flow direction.

5) Before using the machine for aerial work, raise the platform slightly without load to ensure

normal functioning of the machine.

6) Frequent checks should be made of the electricity leakage protection to ensure

effectiveness.

7) For maintenance requirement of the hydraulic system, please refer to Section F3 (C.)

8) If the machine is used frequently, routine maintenance and safety checks should be carried

out every 3 months.

9) Regular check of the chain-drive system for wear and tear at least on a quarterly basis.

Apply N32 oil on chain friction points as well as wheels points as required.

10) Keep machine away from dust and rain. Never store the machine outdoors or in an

area of high humidity or heat. During storage, keep the machine covered with a protective

cover.

11) Only qualified professionals are allowed to dismantle any part of the machine or

conduct maintenance on the machine. If unsure, please contact supplier.

F MAINTENANCE

2. Use and Maintenance of Battery ( DC Models)

When transporting the DC powered personnel lift, the battery casing and battery should be

detached from the rear of the machine to prevent damage to the battery casing.

To prepare the machine for use, install the outriggers, then load the battery box (including battery inside)

onto

To charge the battery, follow instructions located on the machine. When the charger indicator changes from

red to green, the battery is fully charged. Continue charging for about an hour or more, this will ensure

maximum performance of the battery.

If the charged battery has been used or left unused for a period of time, recharging is required, as prolonged

storage at low charge will result in reduced battery performance

Store the battery in a cool and dry area to reduce the loss of power during storage period.

An Absorbed Glass Matt (AGM) maintenance free battery is used. AGM batteries do not include fluid so

unlike Lead Acid batteries they not require the battery’s fluid level to be checked.

Check the battery and the terminals regularly to ensure they are secured tightly in position. Inspect the

insulation casing for worn spots, cracks or broken terminals and repair them immediately.

To connect the battery and the charger, set the power switch to the "OFF" position. Ensure that the positive

terminal on the battery is connected to the positive socket of the charger and vice versa. To commence

charging set the power switch to the “ON” position.

Charging must be carried out in a well-ventilated area, away from inflammable materials as charging may

result in sparks or flames, which may result in an explosion.

Ensure the connecting socket on the battery casing is properly maintained to avoid power

disruption.

Keep batteries fully charged when in storage. Prolonged storage at low charge will result in

reduced battery performance. Disconnect the battery from the machine prior to long term

storage. Store in a cool dry place.

The battery casing carrying the charger contains an ammeter, which indicates the charge

rate. All power usage should stop and the battery recharged, when the power discharge level

indicated by the ammeter reaches 70%. This is strongly recommended to ensure maximum

battery life.

WARNING

Do not charge batteries under direct sunlight or near heat generators.

Battery should be charged immediately after use. If battery is stored without recharging,

performance could deteriorate.

Avoid operating the battery below - 5°C (5°F) or above 50°C (122°F).

Batteries are heavy and should be handled accordingly.

Never disassemble a battery. Clean with moist soft cloth.

Never dispose of a battery into fire. Recycle all used batteries.

Do not short the battery terminals.

1. Uni-directional Valve 2. Relief valve

3. Flow Restrictor 4. Solenoid Valve

5. Oil Cylinder 6. Hydraulic Pump

7. Filter 8. Motor

9. Explosion relief valve 10. Oil Reservoir

Once the hydraulic pump’s motor is switched on, the pump will deliver a high pressure oil flow

into port P of the valve block (shown as dotted line). The unidirectional valve 1 allows the oil to

flow out via Port A and into the hydraulic cylinder. This raises the platform slowly. The relief

valve 2 is adjusted to by-pass oil when the rated capacity is reached. This prevents operation

beyond the pre-set capacity rating. When the operator calls for the platform to descend, solenoid

valve 4 is energized, oil from the hydraulic cylinder then flows back to the valve block via Port A

(The unidirectional valve 1 prevents oil flow through port P). Oil flow can only pass through

solenoid valve 4 onto the flow restrictor 3 and out of the valve block through Port 0 into the oil

reservoir 10. This allows the platform to descend slowly. Due to the pressure balancing design of

the valve block, the ascending and descending speed is not affected by the platform capacity

changes. (Refer Fig 6.1)

(B) UT58 Operating Principle schematic diagram

UT58 comprise of two set of hydraulic systems powered by

M1&M2 respectively and covers the two groups of masts.

M1 is the hydraulic motor which drives the lower four (4)

sets of masts, these 4 lower masts move in synchronism as

the 4 hydraulic cylinders rise. M2 is the hydraulics motor

which drives the upper (2) sets of masts powered by two

hydraulic cylinders.

Ascend control: – Depressing the ascend and power button,

starts the M1 motor driving the four (4) hydraulic cylinders

and the corresponding masts to its maximum position

governed by the limit switch. At this point, the M1 motor is

de-energized, and the M2 motor is energized. The M2 motor

drives the upper series of masts, until these reach their maximum position as defined by its limit

switch. This stops the M2 motor and the maximum platform height is attained.

Descend control: - Depressing the descend and power buttons, first energizes the lowering

hyraulic solenoid allowing the upper series of masts to descend. When this upper series of masts

reaches their lowest position as determined by the limit switch, the limit switch then energizes the

hydraulic solenoid for the lower series of masts, allowing these lower set of masts to lower to

their minimum position.

F MAINTENANCE

(C) Hydraulic System Maintenance

1. The specification of the hydraulic oil used is ISO VG32.

Depending on the frequency of use, the oil may require a

complete change once a year. Mixing of oil with other

fluids and the introduction of any other fluids into the oil

tank is strictly forbidden. Should the oil level fall below

normal operating level, the platform will not reach its

maximum height. In addition, the noise coming from the

hydraulic system during lifting of the platform will

increase and may sound abnormal. If this happens, top up

the oil tank with ISO VG32 hydraulic oil.

2. After using the manual descending emergency valve to lower the platform to its stored position,

please remember to turn the valve knob to its original closed position. The platform cannot be

raised normally unless this is carried out.

3. Do not adjust the hydraulic pressure setting or change any original hydraulic system parts

without obtaining the approval of the supplier of the machine.

4. If operating in continues cold store conditions (-35 degrees C), the use of a synthetic hydraulic

fluid S.A.E.0W is recommended.

NB: When the platform is loaded and raised to its highest point, momentarily press the platform

control’s “POWER” and “DOWN” buttons simultaneously to minimize the impact to the

machine of a change in hydraulic oil flow direction. Thereafter, fully engage these two buttons

to continue the descent.
