Fantuzzi Reggiane MHC 115 — Safety and interlocks: technical cards
General guidance only — always follow the operation and maintenance manual for your specific machine.
Short answers to precise questions on the safety rules and interlocks of the Fantuzzi Reggiane MHC 115 mobile harbour crane, one fact per card, each with its source stated in the text. For the overall picture, see the Fantuzzi Reggiane MHC 115 technical legacy guide.
Fantuzzi Reggiane MHC 115: what are the wind limits?
Operation and travel with the hook up to 72 km/h and travel with block and load or grab up to 50 km/h, according to the use and maintenance manual of the 75 t version and the technical data of the 2008 manual, as set out in the HIT SRL technical cards. On stabilisers the manuals give up to 151 km/h with the boom erected, 151-200 km/h with the boom on the ground and above 200 km/h with boom and tower lowered, the HIT SRL technical desk notes. HIT SRL service technicians report that these limits apply to all MHC cranes; the wind data of the manual of the specific crane are the ones to follow.

Fantuzzi Reggiane MHC 115: what does the ALC anemometer do?
It gives an alarm with buzzer and black-box record of the maximum wind at 72 km/h in work and travel with the hook and at 50 km/h in travel with grab, tongs or spreader, according to the ALC description of the 2002 manual, as HIT SRL's technical desk reads it. After a settable delay above the alarm threshold the same ALC description of the manual blocks slewing, travel, boom lowering and hoisting, as logged by the HIT SRL technical desk. The settings of the manual of the specific crane apply, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115: how does the anti-overload system work?
It shows load, radius and working angle in the cab and gives an audible and visual alarm near the limit, according to the use and maintenance manual of the 75 t version, the HIT SRL technical desk notes. In overload the manual stops the operations and allows only load lowering and boom raising, as set out in the HIT SRL technical cards. HIT SRL service technicians report that this load limiter and the 75%, 66% and 50% load tables apply on MHC 115 cranes in service; the load tables of the manual of the specific crane apply.

Fantuzzi Reggiane MHC 115: which percentages are the load tables given at?
At 75% for heavy use, 66% for intensive use and 50% for grab use, according to the load table of the 75 t version, as recorded at HIT SRL. The table prohibits capacities on wheels and includes the grab weight in the grab capacity, and the load table of the manual of the specific crane is the one that applies, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 115 BDE: when can the electric motor be started?
Only with the crane stabilised and the chassis cable-reel plug connected, according to the 2008 manual, which disables destabilisation and travel while the motor runs, as HIT SRL's technical desk reads it. The same manual does not allow travel with the cable-reel cable connected. HIT SRL service technicians report that the BDE interlocks of the manual apply on the cranes in service. On a given BDE crane, the interlocks to rely on are those described in its own manual.

Fantuzzi Reggiane MHC 115: where are the emergency push buttons and what do they do?
Two in the machinery house, one in the cab, one on the chassis and one on the portable board, according to the use and maintenance manual of the 75 t version, and they stop the crane by braking only, without slow-down, as set out in the HIT SRL technical cards. Before restarting after an emergency the manual has the cause found and the crane checked, and a pressed button is reset by turning it clockwise. HIT SRL service technicians report that all MHC models have emergency push buttons in several positions. The emergency push buttons and their positions on a given crane are those shown in the manual of that crane.

Fantuzzi Reggiane MHC 115: which safety devices does the 75 t version have?
Automatic braking of hoisting and slewing when the joysticks are released or the hydraulic circuit fails, according to the use and maintenance manual of the 75 t version, as logged by the HIT SRL technical desk. The manual also lists a rotary hoist limit switch acting on the safety brake and the pump drive and boom limit switches at the boom hinge, as recorded at HIT SRL. The same manual lists dead-man push buttons, a supercharging safety device and a free-fall device on the winch brakes, as recorded by the HIT SRL technical desk.
