EXCAVATOR VALVING & ACCESSORIES Australia

• Hyspecs manufactures hose burst safety valves (SAFEX TM Valves) specifically for excavators - these valves prevent uncontrolled lowering of the boom/stick cylinders in the event of a hose burst, thereby becoming part of the load holding and lowering system designed to comply with AS 1418.8 / ISO 8643. See pages 25-26.

Hydraulic hoses fail on excavator booms | Resources Safety

20.09.2011· Hydraulic hoses on the booms of the hydraulic excavators, immediately adjacent to the ferrule at the hose-assely end, failed. (During the full range of excavator operations, this ferrule in the hose assely is often immediately adjacent to the inner, right-hand, cab window.) As a result, pressurised hydraulic oil hit the excavator operator''s

13 Causes Of Hose Failure - New-Line Hose and Fittings

Older hoses become discoloured, stiff, or burst at low pressures. 10) Incorrect hose length - Too short of a length does not allow the hose to expand/contract due to changes in pressure or temperature and causes excessive stress on the fittings or hose reinforcement. 11) Twisting hose during installation or service - Twisting a hose rather than naturally bending the hose will reduce life. It

Hose Burst Valves | Tucson Hydrocontrols

06.04.2015· In this way, hose burst protection can be offered safely and securely to almost any hydraulic cylinder, without the use of archaic technology.Since the piping is rigid between the cylinder and the overcentre valve, hose burst can only occur in Line A or between the overcentre valve and the directional control in Line B. In this case, the flow out of the cap end would not change since the load

What Are the Main Causes of Hydraulic Hoses Bursting?

31.05.2019· Although the hose remains bent, you will find it still remains flexible, when a burst such as this occurs. It’s likely that there will be broken wires in the area of failure around the outside bend of the hose. If the hose is flattened in the area of the bend it could restrict the flow of substance through it; this could be caused by a bend occurring to close to the fitting or due to the
