Owner’s Manual
| Version no: 1
Single-phase lift tables incorporate an electrical control board inside an enclosure mounted in the
base of the lift table. An enhanced version of the control board, known as
SmartLift
is also
available. The SmartLift provides on board status indication and other features described in
Section 5.5.1.
Remote power unit lift tables have their switchgear or control board located on the power unit.
Warning
:
Australian Standard AS1418.8 requires lift tables be protected by earth leakage
protection (Clause 3.6.3 (n)). As earth leakage protection is usually effected at the
power outlet, it has not been incorporated into the lift table. Be sure that the outlet
used is protected.
Caution
: You may choose to remove the plug supplied and wire directly to a power supply.
Australian Standard AS1418.8 requires an isolator adjacent to the lift table. Be sure to
incorporate an isolator if you hard wire.
2.1
Operational Restrictions
2.1.1
Wash-down
The standard Safetech lift table electrical equipment is rated to the degree of protection IP43 and is
not regarded as being weatherproof or suitable for wash-down. Safetech can supply lift tables to the
IP56 degree of protection that are suitable for wash-down or external use.
2.1.2
Hazardous Environments
The standard Safetech lift table electrical equipment is not suitable for use in flammable
environments and must never be used when such hazard exists. Safetech can supply specially
modified lift tables suitable for hazardous locations to Class I Zone 2 or DIP rating.
2.1.3
High Cycle Applications
The standard Safetech lift table is designed for intermittent use commensurate with manual loading
and unloading operations. For high cycle operations, the following should be observed:
a)
The standard lift table mechanism is designed to achieve a minimum life of approximately
50,000 cycles before maintenance of pivots is required. For manual intermittent use, this
equates to many years of service.
For high cycle applications, 50,000 cycles may elapse quickly. Safetech can supply lift
tables suitable for high cycle use.
b)
The standard lift table motor should not exceed 10 starts per hour for single- phase
motors and 20 starts per hour for three phase motors. Please consult Safetech if greater
starting frequency is required.
2.1.4
Personnel Lifts
The standard Safetech lift table is designed for lifting goods only and should not be used as a
personnel lift. Safetech can supply personnel lifts to AS1735.3 or lifts for disabled personnel to
AS1735.15 if required.
