Do I need a twinlock hitch?
There are two specific regulations regarding hitches: Firstly, in the event of hydraulic failure such as a hose rupture, the hitch must not allow the bucket or other attachment to be dropped. The second regulation requires that the operator must have read and comply with the hitch manufacturer’s operating regulations at all times. Clearly there is no requirement for twinlock here and the demand for them has been driven by custom and practice on site. A number of companies will modify S-type couplers to twinlock operation but it must be said that this, like any compromise, produces a weaker hitch that is, more likely than not, not CE marked.
engcon’s Q-Safe is marketed as the safest hitch in the world. We make this claim, not only because it satisfies all current regulations, but also because it actively prevents operator mistakes (one of the largest causes of accidents and injuries). Pin sensors ensure that both axles are locked and operate visual and audible alarms when the hitch is open or unsafe; ground pressure sensors ensure that the attachment must be grounded before the hitch can be opened and there is the option to disable excavator boom and slew controls when the hitch is being operated. In short, the hitch operating instructions are hard-wired into the controls so that the operator cannot misuse the system. Furthermore, EC-Oil (engcon’s automatic hydraulic connection system) is available on our Q-Safe system as default.
