Hydreco showcases faster, safer tipper truck solution

Manufacturer expected to display innovative hose burst valve design that enables faster lowering speeds and quicker turnarounds for tipper trucks

Worker safety is paramount today and under VSB6 it is a requirement to have a hose burst valve installed and operational on a tipping hoist to prevent the tipper body lowering in the event of a hose rupture.

However, hose burst valves slow the lowering speed of the body and limit operators’ ability to achieve quicker turnarounds between loads.

In response, Hydreco Hydraulics has developed the new VA40 hose burst valve which has a number of unique design elements that offer improved safety, performance and environmental impact. 

The patented device uses an adjustable flow-dependent check valve (also known as a velocity fuse) that is “de-sensitised” by use of a solenoid valve with a separate tank line. They work in unison to provide reliable hose burst protection.

The flow-dependent check valve is adjustable to suit individual hoist requirements. This design is also more tolerant to oil contamination, meaning it will work when needed in a hose burst condition.

For controlled safe lowering in a hose burst condition a solenoid operated cartridge valve is used to channel the oil from the hoist to tank via an auxiliary tank line, ensuring oil is not spilt.

For ultimate protection, a low-flow bleed screw is provided on the valve body for field emergency safe lowering when power is not available to operate the solenoid.

In a normal lowering operation both the flow-dependent check valve (with extremely low pressure drop) and the solenoid valve (up to 50 L/min additional flow) are operational. This provides faster flow rates on lowering than all other designs.
