HIGH-VOLTAGE HIGH STAKES


Hyster explains what timber operations need to know about servicing high-voltage materials handling equipment


Heavy-duty forklifts are increasingly powered by electric sources such as batteries, rather than internal combustion engines (ICE). To achieve the charging speed and power delivery required by applications with demanding duty cycles and heavy loads, this high-capacity electric material handling equipment relies on high-voltage battery systems.


Not all electric materials handling equipment uses high-voltage batteries. However, for equipment that does, there are important safety considerations for equipment maintenance and service that operations must understand and comply with to prevent electrical danger or injury.


ELECTRICAL SAFETY RESPONSIBILITIES The European Committee for Electrotechnical Standardisation (CENELEC) defines the EN 50110 standard concerning electrical safety. It shows that there is a shared responsibility for electrical safety. The owner of the premises where equipment is being maintained or serviced, their equipment dealer and the manufacturer all need to work together with a shared interest in the safety of work being performed.

While it’s very common for operations with materials handling equipment such as forklifts and container handlers to service their own equipment, maintenance or repair work on high-voltage circuits, often identified by orange cables, requires individuals who
