The entire range of HUNTER Ladders is the only range of ladders which
are manufactured to the high specification demanded by the British
Standard BS EN131 and are fully compliant with the Health and Safety
Executive’s demanding HSE OC200/30 stability standards.

RESEARCH AND TESTING
In 2000 the HSE commissioned Loughborough University to undertake
detailed research into portable ladders and how they are used and how
they fail. The result of their research, published in 2004, is available
on the HSE Website http://www.hse.gov.uk/, document RR205. Their research
led them to identify four potential failure modes
- Base Slip
- Loss of top contact
- Top side slip
- Flip
They also identified the Applied Load Point (ALP) and a Standard
Load Vector (SLV – the direction in which load should be applied)
and the actual loads required to simulate a ladder user approaching the
point of “misuse”. They then produced a Workshop Test Procedure and
a series of tests using the ALP and the SLV and the different loads
needed to identify if a Device Augmented Ladder (DAL) passed these
tests, in which case the ladder was deemed to be “effective”, and
fit for use. For a ladder to be deemed “effective” it had to remain
standing when subjected to all these tests. This is clearly defined
in the WAHR 2005.

DEVELOPMENT
In order to better understand the Loughborough Workshop Test proposals
Ladder Safety Devices constructed a nine metre high test rig (right)
and carried out extensive empirical tests on various prototypes and
was able to develop a system which does indeed prevent failure in all
four of the modes identified by the Loughborough report and thus complies
with the requirements of the HSE as detailed in the HSE Operational
Circular OC200/30 issued on 4/11/05.
The result of that development is the range of
HUNTER Ladders which is unique in being the only range of ladders
which are manufactured to the high specification demanded by the British
Standard BS EN131 and at the same time comply with the Health and
Safety Executive’s equally demanding standards regarding stability,
as defined in HSE OC200/30.

| ADT Fire and Security Environmental Health and Safety Advisor,
Richard Walker (pictured) has been involved in the development of
the Hunter range of ladders for over two years. He says…
"Ladder Safety Devices have provided ADT Fire and
Security with ladder stabilising and levelling equipment since 2000, since
then our ladder accident problems have all but disappeared.
We have worked with LSD to develop what we consider to be the most
efficient, stable and user-friendly ladder available. It is lightweight
and both the leveller and the stabiliser can be deployed in seconds,
as a result of which we have experienced no user-resistance and we
currently have more than 2,000 engineers using these products."

LEVELLER
|
Every HUNTER Ladder is fitted with
an integral leveller in both of its 
stiles, each one capable of providing an adjustment of 125mm (5”)
in increments of 3mm (1/8”).
This will enable the ladder to be set up on a slope of 16 degrees
– the steepest slope permitted by the HSE.
Adjustment is achieved very quickly by positioning the ladder, removing
one of the locking pins, allowing the ladder to level itself, replacing
the pin in the nearest visible hole (which is never more than 1.5mm
(1/16”) away) and turning the pin to lock it. |
|
|
BASE SLIP |
|
The adjustable leveller sections have moulded
feet which are made of specially formulated rubber designed to provide
a very high level of grip on any substrate giving a level of resistance
to base slip which complies with the HSE requirements and far exceeds
that provided by standard ladder feet.
|
|
|
RESISTANCE
TO SIDE SLIP AND FLIP
|
Every HUNTER Ladder has on each
side a one 
metre long stabilising bar which is clamped on below the bottom rung
and hinges down to the ground. A telescopic strut which is attached
at each arms centre point has 30 possible locking positions in increments
of 12mm, to cater for uneven ground. These arms provide excellent lateral
stability and complete resistance to “flip”. |
|
| TOP SIDE SLIP |
|
At the top of every HUNTER Ladder is a pair of
wheels which are clamped to the ladder stiles. The rubber used in
the “tyres” is of a special formulation which provides excellent grip
on any substrate and gives excellent resistance to Top Side Slip.
These wheels are also invaluable when running a ladder up a wall.

THE HUNTER STABILISING SYSTEM RETROFIT
A similar degree of stability and safety can be added to your existing
ladders by fitting the HUNTER STABILISING SYSTEM.
This kit consists of the same wheels that are
fitted to all HUNTER Ladders, the same stabilising arms but with a
clamp for the top mounting instead of a bolted fixing, plus a pair
of levellers which slide over the stile rather than being inside the
stile.
The degree of stability is the same as in all
HUNTER Ladders. The end product is equally user-friendly.
Fitting requires no drilling
Two kits are available, one with wheels, arms
and levellers and one with wheels, arms and feet fitted with slip
resistant rubber.
Only spanners are needed and these are supplied with every kit.
