Improving safety of hydraulic systems by using hose restraints

One solution to guard against an eventual hose whip is to use a hose restraint system. Hose restraint systems are designed to prevent whipping of a pressurized hose in the event of a hose separating from its fitting. They provide an additional level of safety and help prevent damage to nearby equipment or injury to operators near the failed hose by limiting the distance of travel of the pressurized hose after it breaks free from the fitting.
The system is comprised of two components, a hose collar and a cable assembly. The hose collar is selected based on the outside diameter of the hose, and the cable assembly is selected based on the type of hose connection.
One of the Hose Whip Prevention systems is manufactured by Parker. Parker offers two types of cable assemblies – one for flange-type connections, and the other for port adapters.
The hose whip restraint is not to be used in place of proper hose crimping procedures. The Parker hose whip restraint system has been tested to work at operating pressures of the hoses it is designed to work with. It is not meant to increase the hoses working pressure or to add incremental pressure rating to the hose / fitting combination. Your hose-fitting-whip restraint system is rated to the pressure of the lowest rated component of the system.
