HAPP hoist summary
This information is informative only and is subject to change without notice,
refer to specification sheets for current information. The current range of
products is visible on the happ website. http://happ.com.au/products/
Each HAPP hoist uses dual hydraulic rams (one in each column) to lift the carriage
which has the lifting arms connect to them. The ram lifts by pushing a heavy duty
chain connected to the column on one side to the carriage on the other side. Each
hoist has dual safety interlocks (one on each column) which engage independently
as the hoist lifts.
There are three basic styles of 2 post hoists available from HAPP. Floor plate,
Hydraulic and Clear floor styles.
o
The
floor plate
style (Happ30, 35, 70 and 80) connects the columns
with balance cables that balance the load across the hoist carriages
and hydraulic hoses for lifting
across the floor
protected
by a checker
plate cover
between the columns. This plate is approximately 50mm in
height and has an angled surface on each side to enable easy drive
through with vehicles.
The column height of these hoists range from 2.72m to 2.85m
depending on model. The column widths of these hoists range from
3.26m to 3.41m depending on model.
o
The typical
clear floor
style (Happ40 and 60) connects the columns
with balance cables that balance the load across the hoist carriages
and hydraulic hoses for lifting protected by a section of U shaped bar
across between the columns at
the top of the hoist
. The connection
at the top of the column enables the floor to remain clear but introduces
a height restriction. The connecting bar also provides a load sharing
function as each column now has a strut connecting them at the top as
well as the floor via concrete.
The column height of these hoists are 3.68m. The column widths of
these hoists are 3.44m
o
The hydraulic hoist style (HAPP 90) uses a hydraulic control valve to
balance the load between the columns by managing the pressure
supplied to the hydraulics. It is a clear floor style hoist also.
The column height of the HAPP 80 is 2.02m with variable column
width.
The HAPP 90 uses loxon fitting bolts (anchor bolts can be used). The
loxon bolts act like a nut rather than a bolt. Whilst the actual bolt in a
loxon is 16mm in diameter the hole size required is
24mm
to allow for
the nut size.
o
The HAPP 25 and 27 represent 4 post hoists available from HAPP
o
The HAPP 10 is a scissor hoist available from HAPP
