Fantuzzi Reggiane MHC 115 BDE: when does the electric motor stop?
At once on its thermal protection or if its contacts are not connected, and after 3 or 10 seconds on the same hydraulic signals as the diesel engine, according to the 2008 manual, as recorded at HIT SRL. The manual gives default values of 1500 mbar for suction pressure and 20 bar for boost pressure, and adds coupler temperature and oil cocks, as logged by the HIT SRL technical desk. The same manual allows a restart after 10 seconds, also after the diesel engine has been switched off, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: how is the hydraulic system arranged?
A pump drive unit on the diesel engine feeds hoisting and slewing on closed circuits with variable pumps, according to the use and maintenance manual of the 75 t version, as set out in the HIT SRL technical cards. The manual protects hoisting against load fall if a pipe fails with a device on the brake-release circuit, and luffs through variable pumps on a double-acting cylinder with pipe-burst valves, the HIT SRL technical desk notes. The same manual puts steering and outriggers on open circuits and keeps the temperature constant with heat exchangers, as recorded by the HIT SRL technical desk.
