Fantuzzi Reggiane MHC 115: which control system does the crane have?
The ALC system according to the 2002 edition and the ALC description of the 75 t version, and ESX central units in the manuals from the 11/2002 edition, as recorded at HIT SRL. The ALC description gives three slave units on the single-winch MHC 115, as on the MHC 65, 40 and 20, and four on the double-winch MHC 115, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: how is the electrical system built?
With two 205 Ah batteries for controls and engine start, charged by the generator, and 380/220 V from the engine-driven generator, according to the use and maintenance manual of the 75 t version, as HIT SRL's technical desk reads it. The manual uses separate protected and numbered circuits in flame-retardant cables, as logged by the HIT SRL technical desk. The same manual interlocks the cabinet doors against opening when live and fits aviation red lights and a rotating beacon, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: which indications does the control system of the 75 t version show in the cab?
Engine oil pressure, oil and water temperature, fuel level and hour meter, hydraulic oil pressure and temperature, and load indication with overload alarm and boom angle, according to the use and maintenance manual of the 75 t version, the HIT SRL technical desk notes. The manual adds a troubleshooting function and black-box recording, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: can the crane be worked from two stations at once?
No: when the crane is worked from one of its three stations, upper cab, lower cab or portable control unit, the controls of the others are disabled, according to the use and maintenance manual of the 75 t version, as recorded at HIT SRL. The manual requires the cab key to be off before the portable unit can be used, as logged by the HIT SRL technical desk. According to the same manual, movements come from one station at a time, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: how does the ALC drive the boom pumps?
The boom movement output drives two solenoid valves in parallel, for boom pumps 1 and 2, according to the ALC description of the 2002 manual, as HIT SRL's technical desk reads it. The same description gives the MHC 65, 40 and 20 a single boom pump, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115 BDE: what does the electric motor drive?
The pumps, through the pump driving unit, and a generator for air conditioning and work lights, according to the 2008 manual, as set out in the HIT SRL technical cards. The manual feeds the rest of the electrical equipment from the quay plug, greases the motor bearings with EP2 grease and gives the motor coupler its own oil, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: when does the ALC system block boom lowering?
With the crane not stabilised, in overload, with the inclinometer or load cells disconnected, with cable reel motor 1 off, with the stabilisers not fully extended where sensed or in high wind, according to the ALC description of the 2002 manual, as logged by the HIT SRL technical desk. The ALC description of the manual shows each block on the display, as recorded at HIT SRL. According to the same description, the blocks from an open stabiliser switch are recorded in the black box, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: can the boom be raised with the crane not stabilised?
Yes, to bring the crane to a safe condition, according to the ALC description of the 2002 manual, the HIT SRL technical desk notes. The description blocks boom raising when travel is enabled, at the boom raising limit switch and below the minimum radius, and with a spreader fitted when the twistlocks are neither fully open nor fully closed, as recorded by the HIT SRL technical desk.
