| Capacity: |
Unless otherwise stated this is for a uniformly distributed
or evenly distributed load over the entire surface area.
Alternatively:-
i. Half the rated load over half the platform length.
ii. A third of the rated load over half the platform width.
|
| Lift Platform: |
A choice of smooth or slip resisting, tear pattern steel for
the deck plate. Mounted onto a substantial angle-iron sub-frame.
This provides top roll over edges that are square (not radius)
for greater strength, smooth load transfer and flush mounting
of extra equipment, handrail, conveyor etc. |
| Stroke / Travel: |
The vertical distance through which the lift is designed to
move. There are various methods of setting or restricting travel.
Eg. Electrically, by limit switch or mechanically by cylinder
stop tubes. |
| Closed Height: |
The lowest height of the lift platform when in its most compact
position. Fixed or adjustable platform support legs may be included
for accurate height setting or to reduce stress on the armsets.
|
| Extended Height: |
The total of stroke/travel and closed height. |
| Lifting Time: |
Generally expressed as the time taken for a loaded lift to
move through its designed available stroke/travel. As a 'rule
of thumb' if the power pack size is doubled the lift will rise
twice as fast. |
| Lowering Time: |
Usually factory set to be equal to the raise speed. This is
semi -adjustable and can be altered on site by a service/maintenance
engineer. |
| Mains Supply: |
3 phase, 400 volts, 50Hz.. It is recommended that a suitably
fused and lockable isolator is positioned adjacent to the power
pack or lift installation. |
| Control voltage: |
24 volts, D.C.. Others are available upon request. |
| Power Pack: |
Our electro-hydraulic power packs are specially selected for
their reliability and low noise (<70dBA). A built in high
pressure filter helps protect the lowering valve from malfunction.
When power packs are in board, under the lift platform we recommend
the inclusion of an inspection hatch in the deck plate to allow
engineer access for maintenance. When power packs are remote
/ outside the lift we recommend they are fitted onto a drip
tray and the pressure hose is fitted with a quick release, self
sealing coupling. Each lift is usually protected to IP54. |
| Controls: |
A pendant style control station is fitted onto 3 metres of
flexible lead and comes complete with an emergency stop and
deadman (constant pressure) up and down push buttons. Foot operated
control stations are readily available. Lifts can be supplied
ready for wiring into other panels. |
| Cylinders: |
Single acting hydraulic cylinders, complete with a hose break
rupture valve built into the bottom of each lifting cylinder.
The internal bore of the cylinder tubes and the piston rods
are honed and polished to an exceptionally surface (Ra<0.4
microns) and then individually inspected prior to use. The piston
rods are hard chrome plated to a thickness of >25 microns.
To reduce corrosion, loss of oil and contamination, a drain
hose is usually connected from the cylinder back to the tank.
The safety factor by stress calculations is 1.8. The pressure
hoses comply to all main European standards. |
| Construction: |
The scissor arms for most lift tables are profiled solid steel.
A substantial torsion tube is fitted between the armsets to
help ensure good synchronisation and stability even when eccentrically
loaded. Pre-lubricated, replaceable type bearing bushes are
a standard feature. Fe510 steel is used for the precision ground
axles and cylinder bolts. The steel arm roller bearings are
replaceable. For exceptional conditions and heavy duty use we
recommend chrome plating heavy wear parts and including grease
points on each DX bearing or including grease free spherical
plain bearings. |
| Anti-trap bar: |
A perimeter anti-trap bar / safety frame is fitted to the
underside edges of the lift platform to restrict further lowering
should be an obstruction be met. For added safety operator reset
is standard, allowing the lift to be raised and the obstruction
removed. (Subject to scope of supply not excluding control panel). |
| Safety Lock: |
Steel posts are provided to support the lift in a semi-raised
position to allow safer access for inspection, cleaning and
maintenance purposes. |
| Paint Finish: |
Each table is fully protected with a hard wearing 2 component
acrylic resin paint finish. Our standard colours are RAL 5015
Blue and RAL 6011 Green. Most other RAL colours, hot dip galvanising,
stainless steel and many other finishes are available. |
| Documentation: |
A comprehensive, printed owner/operator manual, complete with
standard diagrams, exploded views and spare parts list is provided
with each lift in its own individual front cover for easy identification. |
| Certification: |
Lifts are usually supplied with the applicable certificate
of conformity to EN1570 or with a declaration of incorporation. |
