THIS MACHINE IS NOT

INSULATED!

USE OF THE AERIAL WORK PLATFORM: This aerial work platform is intended to lift persons and his tools as well as the material used

for the job. It is designed for repair and assembly jobs and assignments at overhead workplaces (ceilings, cranes, roof structures,
buildings etc.). All other uses of the aerial work platform are prohibited!

THIS AERIAL WORK PLATFORM IS NOT INSULATED! For this reason it is imperative to keep a safe distance from live parts of
electrical equipment!

Exceeding the specified permissible maximum load is prohibited! See "Specifications - Platform Capacity" for details.

The use and operation of the aerial work platform as a lifting tool or a crane is prohibited!

NEVER exceed the manual force allowed for this machine. See “Manual Force” on page 2 for details.

DISTRIBUTE all platform loads evenly on the platform.

NEVER operate the machine without first surveying the work area for surface hazards such as holes, drop-offs, bumps, curbs, or debris;

and avoiding them.

OPERATE machine only on surfaces capable of supporting wheel loads.

NEVER operate the machine when wind speeds exceed this machine’s wind rating. See “Beaufort Scale” on page 1 for details.

NEVER attach notice boards etc. to the platform, as this will increase wind loading.

IN CASE OF EMERGENCY push EMERGENCY STOP switch to deactivate all powered functions.

IF ALARM SOUNDS while platform is elevated, STOP, carefully lower platform. Move machine to a firm, level surface.

Climbing up the railing of the platform, standing on or stepping to or from the platform onto buildings, steel or prefabricated concrete

structures, etc. is prohibited!

Dismantling the entry gate or other railing components is prohibited! Always make certain that the entry gate is closed and securely
locked!

It is prohibited to keep the entry gate in an open position when the platform is raised!

To extend the height or the range by placing of ladders, scaffolds or similar devices on the platform is prohibited!

NEVER perform service on machine while platform is elevated without blocking elevating assembly.

INSPECT the machine thoroughly for cracked welds, loose or missing hardware, hydraulic leaks, loose wire connections, and damaged

cables or hoses before using.

VERIFY that all labels are in place and legible before using.

NEVER use a machine that is damaged, not functioning properly, or has damaged or missing labels.

To bypass any safety equipment is prohibited and presents a danger for the persons on the aerial work platform and in its working range.

NEVER charge batteries near sparks or open flame. Charging batteries emit explosive hydrogen gas.

Modifications to the aerial work platform are prohibited or permissible only at the approval by

AFTER USE, secure the work platform from unauthorized use by turning the keyswitch off and removing key.

The driving of MEWP’s on the public highway is subject to Regulations made under the Road Traffic Acts.

NEVER elevate the platform or drive

the machine while elevated unless

the machine is on a firm, level

surface.

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.

UpRight Powered Access has a global reputation for innovation and a proud heri­tage in the design and manufacture of high quality powered access equipment.

The company was founded in the UK more than 25 years ago, on the principle of
constantly improving service excellence for end users.
Every model in our growing range of versatile access platforms is a class leader and
together they have set new industry benchmarks.

Our commitment to research and design, plus 250,000sq ft of same site
fabrication, build and support capacity, mean UpRight Powered Access can offer
complete solutions to meet even the most demanding access applications.

UpRight Powered Access has third party accreditation to quality standard ISO 9001
and the full range proudly carries the CE mark, complying with or exceeding all
relevant standards and EC directives.

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.
