INTRODUCTION

The AB46HSRT impressive 14.63m (48ft.) platform height and 7.90m (26ft.) outreach is achieved from only a 2.4m (7.9ft.) jacking width. ‘A’ frame hydraulic outriggers level the Pioneer on sloping or uneven ground.

The AB48HSRT can be levelled on ground with a maximum slope of approximately 5 degrees front-to-rear or side-to-side, with the proviso that all 4 wheels are clear of ground contact.

If after using the outriggers to level the platform any wheel is still grounded, either the slope is too great or the terrain is to rough and therefore the platform must not be elevated.

DESCRIPTION OF EQUIPMENT

The UpRight AB48HSRT is of the parallel linkage vertical boom design, mounted on an all terrain platform. The unique, yet very simple boom configuration gives the maximum safety and control ability combined with a robust construction to withstand a heavy working environment

The AB48HSRT machine is designed for two man capacity (215kg (474lb.)S.W.L.).

The machine incorporates a bottom boom with tie-rod, a short vertical boom and a top boom with a telescope section. The AB48HSRT also has an independent hydraulically operated flick-out boom and rotating cage for extra manoeuvrability.

The hydraulic system is of a failsafe design throughout, with built in hydraulic lock valves on all of the rams as a precaution against hose failure. The machine is controlled by means of proportional manual controls of the ‘direct hand’ lever operating type. These valves are located at both the base and in the cage, as standard.

Electrically operated emergency lowering valves are fitted as standard to allow the machine to be lowered from the base and basket.

The hydraulically operated outriggers are fitted with electronic micro-switches, to prevent the booms from being raised without the outriggers being extended and under load. A micro-switch also prevents the hydraulic outriggers being accidentally retracted while the booms are raised.

Performance.

Maximum Working Height 14.63m 48ft. Maximum Working Outreach: 7.90m 26ft. Capacity (2 man working): 215kg 474lb. Slewing Arc: 900 degrees°

WARNING NOTICES

1. DO NOT operate this machine unless you have been fully trained in its safe use.

2. DO NOT operate the machine on soft, slippery or sloping ground unless

adequate precautions have been taken. The stabilisers are designed to operate on firm level ground with a minimum bearing strength of 50N/cm

The maximum load imposed by an outrigger is 1.8 tonne

Advice should be obtained from UpRight Powered Access as to the type of supports and precautions required before attempting to operate the machine outside these parameters.

NOTE .The AB48HSRT can be levelled on ground with a maximum slope of 5 degrees

front-to-rear or side-to-side, and that all 4 wheels are clear of ground contact.

3. DO NOT use any equipment in the basket to increase the reach or working height of the machine, e.g. ladders.

4. DO NOT fit any additional equipment to the machine that would increase the wind loading, e.g. notice boards.

5. DO NOT use the machine for any application that may produce special loads

or forces: the manufacturer, UpRight Powered Access, must be consulted for approval of special applications prior to use.

6. DO NOT use the machine close to live electrical conductors. The minimum safe working distance for a machine working near overhead power cables is the maximum extended length of the booms plus 15 metres, measured with the booms pointing towards the lines, i.e. safe working distance for the AB48HSRT is 22 metres. It is the operator‘s responsibility to ensure that, when working in the vicinity of live overhead high-voltage lines, the minimum safe working distance is maintained. Erect a simple barrier tape at the safe distance.

7. WORKING CLOSE TO POWER CABLES – if work has to be carried out at less

than the safe working distance, the operator must ensure that the electricity supply has been switched off. Before commencing work, a written permit to work must be obtained from the owners of the power cables or the responsible authority.

8. DO NOT operate the machine unless all four outriggers are down and in full

contact with the ground. The machine must be level and the wheels lifted visibly clear of the surface before the booms are raised.

WARNING NOTICES

9. DO NOT move the machine

with the basket raised and never allow cage or booms to slew into the path of oncoming vehicles.

10. DO NOT operate the machine if the wind speed exceeds 12.5 m/s. Be aware that, when working near high buildings or structures, shielding and funnelling effects may cause high wind forces on days when the nominal wind speed in the open is low. Wind speed can either be measured from the work platform with a hand held anemometer or estimated using the Beaufort Scale.

BEAUFORT WIND SPEED SCALE

The Beaufort Scale of wind force is accepted internationally and is used in communicating weather conditions. It consists of numbers 0 - 12, each representing a certain strength of velocity of wind at 10m (33ft.) above ground in th e o pe n .
