Introduction
Thank you for purchasing a Penny Hydraulics MezzLift. This is our own unique design that
is built in our factory to your specification. Each one is tailor-made and we trust that it
meets with your approval and will provide you with a safe, efficient and trouble free means
of moving goods for many years.
This manual tells you what you need to know about its operation together with some useful
guidance on safety and general care. It also explains the servicing requirements and the
availability of a service agreement should you wish to take advantage of it. We have our
own engineers around the country lead by our Central Service Department to give an
exceptional after sales service.
This MezzLift is designed to be used by trained persons in a workplace to move goods
between two levels It has hold to run control buttons with the control circuits remaining live
whilst the motor picks in on demand. Any gates or doors will unlock automatically as the
lift platform decks at that level and vice versa. Generally any shaft or hoist run is clearly
visible by the operator so that they have complete control over the lifting operation. The lift
is not suitable for carrying persons.
We strongly recommend that each operator of the MezzLift be trained in its use and read
all the details set out in this booklet.

Safety Warning
In the interest of safety all personnel involved in the operation of the lift must read
and understand this operation manual. If they do not then they must not operate the
equipment.
•The lift must not be used for man riding.
•As a minimum requirement the lift should be inspected every six months and
serviced annually by a competent person. The lift also requires a thorough
examination and certificate of test as determined by the competent person or at
least every twelve months. See the Service Requirements section for more details.
•The lift must not be overloaded.
•The lift must only be operated by trained and competent personnel. A training
register is included at the back of this manual.
•Whilst the transfer of goods is in progress access to the area should be restricted to
those personnel essential to the operation.
•No persons should go near the platform when it is raised.
•All safety notices must be adhered to at all times.
•Never interfere with the unit. It should run smoothly at all times, if in doubt call the
HELPLINE telephone number 01246 811475.
•Keep the lift properly maintained by a competent person.
•Where guards or safety gates are fitted always ensure that they are in place before
operating the lift.
•Please note that any control panel may remain live even when the motor is not
running.
•Do not modify or re-install this machine without seeking guidance from Penny
Hydraulics Ltd.

Method of Operation
This MezzLift has hold to run control buttons at both levels. The main power to the hoist
should be left on permanently unless isolated for maintenance. The gates or doors cannot
be opened unless the platform is in position at that level and the main power is on. When
a gate or door is opened the platform is locked in position by the hydraulic system and so
the hoist will not function.
1. Ensure that the working area is clear and that only essential persons are in the
vicinity of the hoist.
2. Ensure that any emergency stop buttons are not deployed by turning them gently
clockwise.
3. Press and hold the appropriate up/down button to move the platform. Note that
there is a delayed start after pressing the button.
4. Keep the button pressed until the hoist stops at the top or bottom. Do not try to
judge the landing but let the platform run into the end stops.
5. The landing gate/door can now be opened for loading or unloading. Close the
gate/door and press the button to take the platform to the other landing.
6. Repeat until the delivery is complete and close all gates or doors.
Only use emergency stop buttons in an emergency.
The control panel remains live even when the motor is not running.
If the MezzLift does not work check:
•Power is on!
•No stop buttons are activated.
•All gates/doors are shut.

6
Fault Finding
Power failure. Should the power supply to the MezzLift be cut off for any reason during
operation the platform will be held in position by the hydraulic brake on the end of the
hydraulic motor.
1. The electric motor has thermal overload protection that may operate after prolonged
use. Leave the unit turned off for an hour to cool down if this is suspected before
trying for normal operation.
2. Occasionally a surge in power may cause a circuit breaker to trip out. Switch off
power and check the appropriate circuit breaker at the distribution board in the
building. Reset if possible and then turn on the lift power.
If the problem recurs phone the HELPLINE or have an electrician check the circuit.
Press a button but the platform does not move.
1. A door or gate is not fully closed. The “Gate Open” light should be illuminated on
the main control panel. Ensure that all gates are closed and that the “Gate Open”
light is not lit. The lift should now work correctly.
2. An emergency stop button has been activated. Check that all emergency stop
buttons are out by gently pulling and turning each one anti-clockwise.
Oil appears at the base of the lift. There has been an internal oil leak. It is still safe to
continue operating the unit but see below. Phone the HELPLINE to arrange for an
engineer to call.
The lift operates slowly and will not go up or down. There has been an oil leak and the
tank is empty. Call the HELPLINE. Do not attempt to refill the tank.
Minor oil leaks from hose connections or the power pack. These are not serious but
call the helpline for prompt attention.
The operator should only use the normal operator controls and must not interfere with the
workings of the lift. If in doubt call the HELPLINE on 01246 811475

Maintenance
As required by LOLER* a competent person must carry out a thorough examination. In
the case of a MezzLift this must be done every six months and will include various tests.
In addition to this there are service operations that must be done on an annual basis.
These are indicated in bold. Various split pins, oils, greases and sealant are required to
complete a full service.
Before starting work on site always inform the manager/site foreman what operation is to
be carried out and of any health and safety issues. The manager/site foreman may have
additional requirements that must be followed.
Never leave an open shaft unguarded. Treat ladders with respect and fasten them into
position. Never work beneath the cradle or platform without setting safety sprags.
Mountings Check top and bottom mountings for security. These are to be re-
examined under full load conditions during the testing procedure
and inspected for movement.
Cradle chain type Visually check chain attachment points on cradle.
Check for free movement of cradle.
Check rollers for free movement and wear.
Grease all 4 axles via nipples on each side.
Chain sets Examine both drive & suspension chains for damage and wear.
Visually check coupling points for security.
Examine all sprockets & clear any debris from behind the bottom
sprocket.
Grease all four chains.
Grease the motor and two bottom bearings via the grease
nipples.
Check suspension chain tensions with the platform near the top.
They should be even with only hanging tension in the fall from the
cradle to the bottom sprocket but no bunching of the chain when the
cradle is lowered. Adjust as necessary using the two adjusters
beneath the top sprocket.
Check the drive chains for even tension. There should be no
bunching of the chain when under load. If they need adjusting
loosen the motor mounting plate bolts and use a bottle jack to push
the assembly up so tightening the chains. Retighten the plate bolts.

9
Hydraulic system Check that power pack is securely mounted.
Check power pack and hose ends for leaks.
Check oil level and top up as necessary using Tellus 32 hydraulic
oil.
Check that relief valve is not causing motor to stall by driving the
platform into the end stops.
Examine visible hose run for leaks and damage.
Check and reposition hoses at the top of the column to ensure
clearance on cradle rear axle.
Test Run up and down five times unloaded. It may not always be
possible to go to the top. Check for smooth running and correct
relief valve operation.
Load with the largest full barrel available and run up and down five
times. Check that the flow control valve gives correct speed of
descent. Check for partial porting of the control valve leading to
loss of control over descent. Adjust relief valve to give constant
speed of ascent. Examine hoist mountings.
Repeat the unloaded test. Check for leaks. Check rope or chain
tensions.
General Check for correct operation of all door locks.
Check for correct operation of all proximity switches.

Data
Power Supply
The lift requires a 20 Amp/240 Volt 50Hz single-phase electrical supply or 2.2kW, 415V
three-phase and neutral. This should be terminated in a switch with a neon live indicator. If
circuit breakers are employed in the system then they must be of a type that can cope with
the surge of an electric motor.

Noise Levels
A survey sheet giving full details is available on request. Briefly, the results are as follows:
-
Hydraulic pump motor running 72dB(A)
Lift operating when loaded 68dB(A)
Lift operating when unloaded 71dB(A)
These levels are well below those at which hearing can be damaged and below levels at
which action is required under the noise at work regulations.
COSHH
Hydraulic oil is Tellus Type 32 and is not considered hazardous as defined by EC
legislation. Any spillage should be wiped up not flushed away. Penny Hydraulics will
collect and dispose of rags or sand used to soak up oil in an approved manner. Contact
with the oil should be avoided as it may cause transient irritation. Wash the affected areas
with soap and water or in the case of eyes just water. If irritation persists then seek
medical attention.
Terminal Disposal
Penny Hydraulics will remove and dispose of the entire lift in an environmentally sound
manner when required.

Survey, Installation and Commissioning
This Penny Hydraulics lift is manufactured to a high standard and can be installed in many
diverse situations. Since no two applications are the same the lift is custom made following
a site survey and risk assessment.
It is assembled in the factory and delivered on site generally in a single section and cannot
be altered. It is therefore essential that when the original survey is carried out that all
dimensions and facts that may affect installation are correct. The following section explains
the important points at the various stages.
Survey
A trained person must carry out the survey and complete a Site Assessment Form, as it is
part of the installation risk assessment and layout evaluation. A quotation may be derived
from an architect’s drawing but a site survey is essential as the job progresses to take a
full account of the special requirements of the task and location.
Installation
All installations must be carried out by qualified engineers trained in the method of
installation and approved by Penny Hydraulics. It is important to note that should a non-
approved engineer on installation cause damage or fault this could invalidate the warranty.
•Clear the working area.
•Check all dimensions before unloading.
•Manoeuvre the lift into position noting that this will normally require a crane
mounted on the delivery vehicle or chain blocks fixed inside the building. Lifts can
be made in two or more sections to aid manual handling and then assembled in
position.
•Bolt the lift to the floor and back wall or frame work. It is essential that a sound fixing
is obtained at the top of the lift. Welding may be required.
•Locate and mount the power pack such that the operator is in a safe position at the
bottom but has sight of the lift.
•Erect any guarding necessary as previously agreed. This is sometimes done earlier
in the installation process depending on site circumstances and how the lift fits into
the structure.
•Couple all electric and hydraulic connections. They must all be fastened securely
and neatly back. It is possible to commission lifts on a temporary supply and then
an electrician couple into a permanent supply prior to the lift going into service.

14
Commissioning
•Carry out pre-commissioning checks:
1. All hose connections are tight and not leaking.
2. Hoses to be fastened back securely
3. All nuts and bolts are tight and safety lock pins in place.
•Switch on power and listen to the motor running smoothly.
•Operate handle up and down and check for correct direction.
•Run platform up and down empty five times.
•Run the loaded platform up and down twenty times. Where necessary sling a 25%
overload beneath the platform. Check hoist mountings for security.
•Check the speed of descent. Adjust to a maximum of 0.75 metres/sec.
•Remove load and run the platform for a further five times up and down noting the
platform should run smoothly at all times and the rollers remain cool.
•Check for any oil leaks on hose connections, around the power pack and at the
base of main pillar.
•Check power pack mountings, minimum two M8 bolts.
•Check that the main lift mountings are secure to the floor with a minimum of two
M10 bolts or equivalent other fixings.
•Check that the main lift mountings are secure to the back wall with a minimum of
two M10 bolts at each side or equivalent other fixings.
•Check for correct operation of all lift features and safety devices particularly gate
locks and proximity switches.
•Where applicable check that the platform locks in the folded position and that the
safety hook is in place.
•Check that all notices are posted correctly.
•Train an appointed person on site in all operational procedures and safety
precautions. Enter their details in the training register at the back of this manual.
•Enter your own details on the work record.
•Make out a test/commissioning certificate.
