Machine Safety: Conveyors Standards Update

Machine Safety: Conveyors Standards Update

Our interaction with machinery is constantly evolving owing to rapid advancement in technology and business processes. As a result the safety standards for machinery need to be continuously reviewed and updated.  The once current AS1755-2000 “Conveyors’ Safety Requirements” has recently been replaced by a series of new standards due to some oversight for the way that conveyors are used.

The AS1755 when it was introduced, specified broadly the minimum safety requirements for the design, installation and guarding of conveyors. While it attempted to cover all the conveyors, it didn’t address the specific differences of conveyors used in diverse environments for different purposes. These days conveyors are utilised in a wide range of applications from carrying light loads over short distances (such as in pharmaceutical industries) to large conveyors transporting tons of materials over many kilometers (such as in mining and heavy industries).

The new standards supercedes the requirements in AS1755-2000
  • AS/NZS 4024.3610, General requirements;
  • AS/NZS 4024.3611, Belt conveyors for bulk material;
  • AS/NZS 4024.3612, Chain conveyor and unit handling;
  • AS/NZS 4024.3614, Mobile and transportable conveyors.

The new AS/NZS 4024.3610 provides general requirements applicable to all the conveyor systems and shall be used in conjunction with other standards of this series according to the type of conveyor used.  For example for a bulk material handling conveyor the design, installation, commissioning and maintenance of the conveyor system have to comply with both the AS4024.3610 and AS4024.3611.

  For all applications

The new conveyor standards, which fall under the AS4024.3 series of standards, are tailored in a way to address the diversity of conveyor applications and get into details of the technological requirements according to the type of the conveyor. They deal with the wide variation in design and operating environment for the conveyors which requires a wide range of the safety strategies to control the specific risks for the specific conveyors.
