FOREWORD

The mast climbing work platform is provided with a rack and pinion drive.

The mast climbing work platform can be quickly moved and is easy to transport.

The mast climbing work platform can be fitted with one or two masts and can be freestanding or anchored.

The mast, which consists of separate elements, can easily be adjusted in height to match the height of the building work. The mast is easy to assemble from the platform.

Read this instruction manual carefully before using the mast climbing work platform. Take all the safety precautions as described in chapter 3 into account.

The platform can be adjusted to the shape of the façade. The MSHF mast climbing work platform has a control system which makes it possible to stop at any desired height.

Every care has been taken in the construction of the mast climbing work platform to ensure that all safety aspects have been considered.

Depending on the application area, a choice can be made from different platform lengths, platform widths and permissible loading.

This instruction manual describes only the basic machine, in the standard form supplied by HEK Manufacturing BV.

COMPONENTS

2-1MSHF • 7295-026A

2. COMPONENT DESCRIPTION

2.1 General description

The basic set of the mast climbing work platform with rack and pinion drive consists of the following 5 main parts:

* drive unit * mast * platform elements and fences * chassis or ground frame * control system

The drive unit moves along the mast with the aid of Nylontron rollers. The motors are fitted with centrifugal brakes which retard the platform if the speed of descent is exceeded.

The drive unit, operated by 2 electric motors, is moved along the mast by means of a single pinion on each motor. For a mast climbing work platform with two masts, the motors are automatically controlled to ensure parallel operation.

Much consideration has been given to simple and safe assembly and disassembly.

A crane on the platform (option) ensures that the mast elements can be positioned quickly and safely .

The platform can be adjusted to suit the required working situation with the use of separate platform elements. The width of the platform can be adjusted by means of outriggers.

Fig.2-1 Basic set MSHF chassis/ground frame

Page 26

COMPONENTS

2-2 MSHF • 7295-026A

All electrical connections, which must be disconnected for transport purposes, can be made by means of connectors.

The electrical installation is divided over three boxes:

- The control box on the platform.

- The connection box on the chassis (only when a chassis is used)

- The control box on the tow bar (only when a chassis is used)

The simple construction ensures that only a minimum of maintenance is required.

The mast elements, the chassis, the drive unit, the cable guides and various other components are protected from corrosion by an appropriate surface treatment.

Right-hand: Viewed from the step side, the machine is fitted to the right-hand side.

Fig.6-1 Position machine

If assembly work must be interrupted, this must be done in such a way that, when the work is restarted it is clear what stage had been reached when work was stopped. For this reason always complete a part of the assembly , for example, assemble collect or secure all the components for a connection, complete a ground support or completely assemble an anchor before stopping work.

While the mast is being erected, no more than two persons with a single mast machine or four persons with a twin mast machine, may be on the platform, so that no more than 75% of the lifting capacity is used. The assembly must always be followed by a test run, as described in section 7.3. Until the test has been performed, the platform may not be used for any purpose other than transporting its own mast elements and anchoring components.

The loading of the mast climbing work platform must be planned so that when, in the assembly situation, the maximum height of the mast above the last anchor is reached (the maximum distance between anchors), the material load on the platform is a minimum.

6.2 Ground support

Before the position for the mast climbing work platform is prepared a check must be made to ensure that the distance between the mast and the working surface can be spanned by the standard anchoring material.

1. Ensure that the forces are spread

over as large an area as possible.

2. The soil must be able to withstand a

ground pressure of at least 2 kg/cm² / 30 lb/in². If this requirement is not met, soil improvement must be carried out such that the ground satisfies this minimum requirement.

3. The ground support must be flat and

centrally loaded with a minimum ground support of 400x400 mm /

15.7 x 15.7 in.

When a chassis is used, a ground support must be placed under the jack close to the mast and under the jack of the 4 extending legs. The frame must have a support placed under the mast and under the 4 corners (not under the jacks).

4. The ground support must be durable

and of such a quality that the load can be transferred without plastic deformation.

5. If the machine is installed on a

concrete foundation or on a hard road surface, the installation must be provided with wooden packing to prevent slipping.

Fig.7-4 Push-buttons control box

Page 65

OPERATION

7-5MSHF • 7295-026A

1. Open the trap door in the platform.

2. Remove the toolbox.

3. The motors have a lever which permits the brake to be released.

4. When this lever is operated, the platform will begin to descend. For a two-mast construction, the brakes must be released by two persons simultaneously so a clear system must exist between them.

The speed of descent will be limited by the centrifugal brake.

After a maximum descent of 5 metres / 16.4 ft, stop the platform for 2 minutes in order to avoid the centrifugal brakes becoming overheated, which will result in their working less efficiently .

5. For a two-mast construction, take the opportunity during the stop situation the set the platform level with the aid of the brake release mechanisms. If the platform becomes excessively inclined, the autolevel safety system will come into operation. In this event, external help will be required.

9.3 Autolevel mechanism check

1. Raise the platform by three metres.

2. Operate the brake release

mechanism on one drive unit. The autolevel safety mechanism must now operate.

3. Set the platform back in the horizontal

position with the "UP" push-button.

4. Repeat the previous step for the

other unit.

5. If the autolevel safety mechanism

does not function correctly , the mast climbing work platform must not be used! Consult your service engineer .

9.4 The motor brake

The motor has a built-in electromagnetic brake. This brake functions according to the "normally ON" principle, that is, when the motor has no power supply the brake is active and the motor shaft will be braked. (n = 0 rev ./min). The braking effect is achieved by friction between several discs and the brake must be used "dry" (not greased).

Fig.9-1 Drive unit brake release

Page 74

MAINTENANCE

9-4 MSHF • 7295-026A

9.4.1Operation

The brake mechanism has a metal rotor (3) with friction material on both sides. Four pressure springs (5) in the stator exert an axial force on an anchor plate (2). This anchor plate is pressed by the spring force against rotor. The rotor is mounted on the motor shaft in such a way that it can slide in an axial direction along the shaft. Because the anchor plate presses against the rotor, the rotor is pressed against the friction plate (6). The contact between the friction material on either side of the rotor, the anchor plate and the friction plate results in the required braking effect.

The stator has a built-in braking coil (1) which produces a strong magnetic field when a DC current is applied to it.

When the brake is to be released, a current is made to flow through the braking coil. The resulting magnetic field "pulls" the anchor disc toward the stator , thus releasing the brake.

It is also possible to release the brake manually . If the manual release lever is pressed in the direction indicated by the arrow on the cover, the anchor plate is moved against the spring pressure with the aid of two ball bolts, so that it is pressed towards the stator, releasing the brake.

Fig.9-2 Motorbrake

Page 75

MAINTENANCE

9-5MSHF • 7295-026A

9.4.2Maintenance

In normal use the motor brake is more or less maintenance free. However, after frequent raising and lowering of the platform it may be necessary to adjust the air gap between the anchor disk and the stator, and if necessary , to replace the rotor.

In order to check the condition of the brake, the width of the air gap "a" and the thickness of the friction material on the rotor must be measured every three months.

The air gap "a" is adjusted by the manufacturer to 0.3 mm / 0.012 in and must never be more than 0.9 mm /

0.035 in. The total thickness of the rotor (including the friction material) must not be less than 9.5 mm / 0.37 in.

T o check:

1. Switch off the mast climbing work

platform at the main switch and secure the switch with the padlock.

2. Remove the brake release

mechanism using an open ended spanner.

3. Remove the fan cover from the motor.

4. Use a feeler gauge to measure the

width of the air gap "a" close to the three hollow adjusting bolts (6).

5. Remove the rubber dust ring and use

a vernier calliper gauge to measure the thickness of the rotor. Replace the rotor if the thickness is 9.5 mm / 0.37 in or less.

Fig.9-3 Motorbrake

Page 76

MAINTENANCE

9-6 MSHF • 7295-026A

6. Adjust the width of the air gap "a" as

follows:

- Use an open-ended spanner to turn the three hollow adjusting bolts (6) further into the stator. Ensure that these bolts are all screwed into the stator by the same amount.

- Use a feeler gauge to measure the width of the air gap "a" close to each of adjusting bolts and turn the bolts until the gap by each bolt is just 0.3 mm / 0.012 in wide.

The adjustment of the hand release may not be changed, not even when air gap "a" is readjusted, as security can be adversely affected.

7. Mount the rubber dustring, the fan cover and the brake lever.
