6. Safety Assessment
The Quikstak has been designed to be as safe as possible without restricting the ease-of-use
and versatility of the machine.
Before the Quikstak is used for the first time, a site-specific Hazard and Risk Assessment
should be completed as per
§6.3 .
6.1 Safety features
Safety features of the standard Quikstak design include:
1. A perspex guarding panel which limits access to moving parts.
2. Straddle outriggers which provide a large, stable floor footprint.
3. A speed-limiter which automatically engages when the forks are above 500mm.
4. A crush-safety button on the tiller which, if pressed against the operator’s body,
quickly reverses the direction of travel.
5. An EMERGENCY STOP button which if pressed immediately disable the stacker.
6. An overload valve which prevents lifting excessive loads (more than 1000kg).
7. A pressure-compensating lowering valve which automatically regulates the lowering
speed regardless of the weight of the load.
8. An LED strobe light which is flashes when QUIKSTAK MODE is engaged, providing a
visual cue that the forks are under automatic control.
9. A PLC control program which prevents the forks from descending below 200mm
when QUIKSTAK MODE is engaged.
6.2 Reasonably foreseeable misuse
Reasonably foreseeable misuse considered in the standard Quikstak design includes:
1. Attempts to use the machine by untrained operators;
2. Attempts to lift unbalanced or poorly-built pallets;
3. Attempts to use the machine with unapproved attachments;
4. Attempts to ride on the machine while travelling
5. Attempts to clean the machine without following proper procedures.
6.3 ISO12100 Hazard and Risk Assessment Guide
In most jurisdictions, health and safety legislation requires machinery owners to assess the
safety of their machinery
in the actual conditions of use, considering all relevant factors such
as the area the machine is to be used, the training of operators, the proximity of other
persons, frequency of use, etc.
The following section uses the ISO12100:2010 risk assessment model to assist Quikstak owners
in carrying out this process. Hazards intrinsic to the Quikstak are pre-filled, while blank spaces
are provided to assess application-specific hazards.
