MH100 EXCAVATOR MOUNTED TRENCHER
In order for us to draw up the right specification for the MH100 EXCAVATOR MOUNTED TRENCHER, please check and/or confirm the following:
1. That the excavator to be used weighs at least 10 tonnes when a MH100 with 75 mm (3") pitch digging chain is to be used or 12 tonnes when a MH100 with 101.6 mm (4") pitch chain is to be used.
2. That the excavator is fitted with a Hydraulic Hammer Circuit with large diameter pipes. The return line in particular should have a large pipe to guarantee a low back pressure.
3. Check the flow and pressure available at the end of the Hammer Circuit: it is not enough to simply look at the excavator's general hydraulic specifications: what is available on the hammer circuit when the excavator is slowly creeping backwards ?
Hammer Circuits often incorporate a control valve to reduce the hydraulic flow and/or pressure to suit a particular hammer. For example, it would be quite normal to reduce the pressure to the Hammer Circuit from a system pressure of 250 bar or more, to 120 bar. This reduces the amount of power available to the trencher by 50% and therefore it would be necessary to readjust the control valve to restore the maximum pressure to the Hammer Circuit.
Ideally the MH100 should have 200-225L/min at 300-350BAR.
4. Check that the hydrostatic drive to the tracks or wheels of the excavator will still work when the auxiliary supply (Hammer Circuit) is being used. If the auxiliary supply (Hammer Circuit) is not supplied by an independent pump, make sure to measure the hydraulic flow in the Hammer Circuit (point 3 above), while the excavator is moving slowly.
5. Check the type and size of the fittings at the end of the Hammer Circuit.
6. Check the size of the mounting pins required to attach the trencher to the excavator arm or to any quick release system which may be used.
7. Larger hydraulic motors of the types fitted to the MH100 require a so-called "case drain", a third small diameter pipe, to feed the internal spillage of the motor directly to the hydraulic tank of the excavator.
A pressure relief valve system can be fitted to the trencher as an optional extra to feed the case drain into the return line of the Hammer Circuit, but a separate small line to the hydraulic reservoir of the excavator is to be preferred (and also is much cheaper and more reliable).
