VOH451 SERIES
Liquip is excited to release the VOH451 Series manhole cover,
which is the first and only double drop tested hatch to meet
the newly released Australian Standard AS2809:2020.
The VOH451 manhole cover offers a large easy access
452mm (17.8”) diameter Manhole Cover entry which meets
AS2809:2020 & AS2865 confined space entry.
Liquip’s VOH451 Series manhole covers come standardised in
cast aluminium with metric threads. The VOH451 manhole
cover is also equipped with four provisions for conveniently
mounting additional equipment such as overfill probes,
vapour vents, dip & fill tubes and Diptronic® tank gauging.
Australian & CEN drop test approval makes the VOH451
manhole cover ideal for both top and bottom loading.
Liquip’s VOH Series manhole covers have long been the
industry choice for manhole covers due to Liquip’s no
compromise approach to safety.
AS2809 up until the AS2809:2020 revision required manhole
covers to be dropped on a certified drop test apparatus, which simulates a full compartment of product, from a height of 1.2 metres & then a secondary drop from 1 metre.
This double drop replicates a tanker’s initial impact and often subsequent secondary impact i.e. rollover. An Australian double drop test approved manhole cover provides the highest level of product
