LATFORM
The MB20/26 platform is large enough for two operators and has a free-draining
perforated floor with 150 mm toeboards. Hand-rails are constructed from aluminium
tubing and a safety drop-bar is provided at the entrance. Safety harness anchor points
are also fitted in the floor of the platform. These must be used at all times. The main
controls are fitted to this platform.
P
LATFORM
C
ONTROLLER
The primary (Upper) control box is permanently fitted to the front of the platform. It
features a joystick which provides proportional control for raising or lowering the mast,
raising or lowering the jib or rotating the complete mast assembly. The same joystick is
also used to drive and steer the machine.
A safety Interlock Switch or ‘deadman button’ is incorporated into the Joystick. It must
be activated at all times in order to operate any function. This feature allows for one-
handed operation. A comprehensive explanation of control functions is given in the
Operators Manual - a copy of which shall be located in the platform document wallet
located just beneath the upper control station in the platform.
The secondary (Lower) control box is fitted to the mast cover at arm level. It features a
‘deadman’ enable button and selector buttons to provide pre-programmed speeds for
all functions except drive and steering. This control station is used primarily for service-
type operations including pre-operation inspection. It should never be used to position
a manned or unmanned platform. It may be used in the event of emergency, however,
to lower the manned platform.
E
LEVATING
A
SSEMBLY
The platform is raised and lowered by a combination of a steel jib and a series of
telescoping mast sections. The main hydraulic cylinder, mounted within the masts, lifts
the first mast directly. The other masts are connected by a system of heavy duty plate
chains and pulleys to ensure sequential lifting.
A parallel system of heavy duty straps ensures that the masts descend in the proper
sequence and also ensure that a mast cannot be held in suspension by an obstacle
during descent.
The jib cylinder provides a lifting arc to the jib and cage assembly. All hydraulic
functions are carried out using solenoid operated control valves. Each cylinder features
an integral holding valve to prevent uncontrolled descent in the case of a hose bursting.
WARNING
!!
DO NOT use the work platform without guardrails properly
assembled and in place.
WARNING
!!
NEVER operate the machine from the upper controls until the
platform entrance drop-bar is in the fully lowered position and the
safety harness is fitted.

EAR
The complete mast, jib and cage assembly can be rotated to provide a maximum
outreach of 2.6m in the case of the MB20 and 2.96m in the case of the MB26 machine.
This dimension is measured from the centreline of rotation and is carried out by means
of an integral hydraulic motor driving a Worm Drive Unit, around a Slew Gear.
D
RIVE
& S
TEER
S
YSTEM
An electronic controller, mounted in the chassis, is pre-programmed to adjust the upper
speed limit of each individual function. The controller limits the rotational speed of the
electronic motor and oil pump, thereby limiting the maximum oil flow rate.
The following functions are controlled and driven by the electro-hydraulic system:
•Traction Drives (Fwd & Rev) mast stowed/mast raised.
•Steering and Jib elevation.
•Mast elevation, descent and rotation.
•The Jib descent function is gravity operated and is determined by built in flow
regulators.
P
OWER
S
YSTEM
The Power System (Prime Mover) incorporates four 6V batteries driving a 4KW electro-
hydraulic pump. The pump drives all hydraulic cylinders and the traction drive motors. A
single multi-valve control block diverts the oil pressure to the individual actuators. The
oil flow rate is limited by the pre-programmed speed setting on the motor but is
determined by the position of the joystick in the Upper Control Box.

NSPECTION
This Safety Inspection shall be carried out by the owner immediately prior to
transporting this machine.
This Safety Inspection shall also be carried out by the user prior to use each day.
The procedure is to carry out the following 14 checks in order as follows.
1. Remove the rear chassis covers by means of the two top twist-locks and the two lift-
and-turn catches at the sides. The cover is removed by sliding it backwards and
upwards. Use the central handle provided.
2. Ensure that the mast and jib are fully lowered. Remove the hydraulic oil filler cap and
check that the hydraulic oil level is correct. Oil should be visible on the dip stick. Top up
as necessary using hydraulic oil Viscosity Grade ISO 46.
3. Inspect the chassis area for oil leaks, loose parts, frayed cables and hoses and
structural damage etc. Check that all cable connections to the solenoid valves are
intact.
4. Open the Inspection hatches on both sides of the upper mast cover. Check that the AC
mains cable is disconnected from the battery charger. Check the electrolyte level in
each battery cell. Top up as necessary with distilled water only.
5. Use the automated battery top-up system fill the batteries to the correct electrolyte
level. This is done by opening the shut off valve and pressing the green fill button for
approximately 10 seconds, then re-closing the shut-off valve.
Batteries should be examined for cracks, acid leakage and terminal corrosion. Take
corrective action immediately if either check fails.

2. Operation & Specifications
Figure 4: Lower Control Panel
6. Prior to operating the functions, check that the upper and lower emergency stop
buttons on each control station are retracted; turn clockwise if necessary. Carry out
the following function from the Lower Control Station.
NOTE: DO NOT enter the platform at this stage.
7. Check jib operation by extending the jib to its fully elevated position. Check for
correct routing of the hoses and cables. Check the Emergency Lowering feature of
the jib. Ensure that when the Emergency Lowering lever/button is disengaged, the jib
no longer descends. Return the jib to its rest position using the normal Lower Control
Station.
8. Check mast chains by elevating the masts approximately 30cm above the rest
position. Check for correct routing of the energy chain. Raise the masts to full height
and check for correct adjustment of each lifting chain as follows. Each chain in the
pair should bear load. Use a hand held spring balance or tensiometer apply a
nominal load (approximately 10kgf.) to either chain in the pair. Apply the load about
half way up the chain. Record the approximate deflection i.e. the offset distance from
the mast. Repeat the measurement on the adjacent chain at the same location.
Chains bearing equal load will deflect equal amounts. Carefully adjust the slack chain
until the deflections are approximately equal. Torque up the locknuts to 70 Nm.
NOTE: Apply a thin layer of grease to the lifting chains with a small paintbrush.

2. Operation & Specifications
The function of the mast straps is to ensure that masts descend in the correct order
and more importantly, that masts cannot continue to descend if the jib or platform
meets an external obstacle. Raise the masts about 30cm. Check the external mast
clamp screws for tightness. Pull on the short length of each strap and check that they
are secure. Refer to the maintenance manual for instructions on more stringent
periodic checks on these straps.
Check the Emergency Lowering feature of the mast. The lever is located in the upper
mast over. Open the left hand battery inspection hatch and locate the ‘Emergency
Lowering’ decal label. Check the wear pads for damage or heavy scoring. Replace as
necessary.
9. Elevate the jib fully. Using the Lower Control Station, turn the mast assembly through
about 90 degrees. Check the correct routing of the hoses and cables and the correct
smooth operation of the energy chain in its chassis base slide. Continue rotating
through 180 degrees in both directions. Confirm that the rotation stops are intact.
10.STANDARD PLATFORM CONTROLS Repeat the mast, jib and rotate functions from
the Upper Control Station in the platform. Check that pressing the emergency stop
button prevents subsequent operation of the joystick.
11. EMERGENCY OVER-RIDE While in the platform, ask a colleague to deflect the tilt
alarm sensor body. This sensor is located on the chassis base. The alarm will sound
and all normal function will become interrupted.
Figure 5: Joystick and Tilt Sensor
12.MACHINE TRAVEL - UNELEVATED Travel functions are possible only from the
platform Upper Control Station. As with all such controls, the deadman handgrip switch
must be depressed before any function can operate.
Select Drive on the upper control panel. Pushing back and forward on the joystick
moves the machine backwards and forwards respectively.
The pothole protection will begin to retract immediately. However, full demand speed
will not be realised until the bars are fully raised. This takes about 3 seconds. Check
that the motion alarm DOES sound during travel. Check that the thumb operated
switches on the top of the joystick operates the front wheel steering.
13.MACHINE TRAVEL-ELEVATED While the masts are raised, it is possible to drive and
steer the machine at a much reduced speed. Also note that while the masts are raised,
the pothole protection bars should be fully extended and should remain extended
during slow speed motion of the machine.

RUCK
The MB20n/26 can be carried on a suitably rated transportation vehicle or trailer.
Because of its high gradeability, the machine can be driven under its own power on to
a standard loading ramp (Up to 14 degrees).
It is recommended to reverse the machine up on to the truck thus forward travelling
down the ramp at the delivery point. Winch-assisted loading is allowable for larger
slopes, however, operate the trucks assist winch at minimum speed to avoid over-
pressurising the hydraulic system in the machine.
When the MB20n/26 is on the truck or trailer it should then be made secure by:-
1. Chocking the wheels.
2. Securing with adequate chains or straps to the lifting lugs on the chassis.

system.
To tow the vehicle or to winch it on to a truck it is necessary to hydraulically bypass
the control valves and release these brakes.
CAUTION

DO NOT loop straps through the cage, ladder or jib as this could
cause permanent structural damage during transportation.
