Fantuzzi Reggiane MHC 200 — 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 200 mobile harbour crane, one fact per card, each with its source stated in the text. For the overall picture, see the Fantuzzi Reggiane MHC 200 technical legacy guide.
Fantuzzi Reggiane MHC 200: what are the wind limits?
According to the technical data of the 2000-2006 manuals, the crane works up to 72 km/h and travels up to 72 km/h with the hook block only and 50 km/h with block and grab, as logged by the HIT SRL technical desk. Stationary on stabilisers, the same data give the boom erected up to 151 km/h, the boom on the ground from 151 to 200 km/h and boom and pylon lowered above 200 km/h. HIT SRL service technicians report that 72 km/h in service and 50 km/h in travel with a load or a grab are the limits applied, and that above the limits the boom and then the column are lowered to the ground, also when the crane is parked. The wind table of the manual of the specific crane applies.

Boom on the ground above 200 km/h and mast lowered as well above 270 km/h, according to the 2002 use and maintenance manual, against the 151 and 200 km/h of the technical data of the other editions, as recorded at HIT SRL. The same manual allows work and travel up to 72 km/h, as logged by the HIT SRL technical desk. The wind table of the manual of the specific crane is the one to follow, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 200: what does the anemometer do when the wind limit is exceeded?
After an audible pre-alarm, it blocks slewing, travel, boom lowering and hoisting when the limit is exceeded for more than 5 minutes, according to the 2002 use and maintenance manual, as set out in the HIT SRL technical cards. HIT SRL service technicians report that the same block after 5 minutes also applies on cranes with ESX control units. The manual of the specific crane gives the settings that apply.

Fantuzzi Reggiane MHC 200: how does the anti-tilting system work?
According to the 2006 manual, it computes the actual load from the load cell and the boom angle, warns at 90% of the permitted load and stops hoisting and boom lowering at 105%, recording the event in the black box, as logged by the HIT SRL technical desk. The manual selects grab or hook tables automatically and lets the operator set the hook or spreader table at 66% or 75% where available, and the manufacturer's training material of 2003 gives the grab table as 50%, as recorded at HIT SRL. HIT SRL service technicians report that these values apply on MHC 200 cranes in service; the load tables of the manual of the specific crane apply.

Fantuzzi Reggiane MHC 200: how is the crane stabilised?
On flat and solid ground with the beams fully extended, the crane levelled within +/-0.5% and the tyres fully off the ground, according to the 2006 manual, with periodic level checks during work, as HIT SRL's technical desk reads it. The manual raises or retracts the stabilisers only with tower and boom in travel configuration and slewing locked, and asks for timber or steel plates under the pads if the bearing area is insufficient, as recorded by the HIT SRL technical desk. HIT SRL service technicians report that this procedure applies on MHC 200 cranes in service; the manual of the specific crane gives the ground data.

Fantuzzi Reggiane MHC 200: when is the turret slewing lock pin used?
For travel, parking and strong winds with the boom, or boom and tower, on the ground, joining turret and truck at 0 or 180 degrees, according to the 2006 manual, as set out in the HIT SRL technical cards. The manual unlocks the turret only with the crane stabilised and the wind below the alarm threshold, the HIT SRL technical desk notes. In the same manual the locking cylinder drops each time the machine is switched off, as recorded by the HIT SRL technical desk.

At the top hook position, when only the safety turns remain on the drum and at the intermediate raising position tied to the boom radius, according to the 2006 manual, as set out in the HIT SRL technical cards. According to the same manual, an encoder in the same block slows the movement before each stop, the HIT SRL technical desk notes. The manual has the operator check the limit switches without load before starting work, as recorded by the HIT SRL technical desk.

They stop luffing at maximum and minimum radius and at intermediate lowering positions linked to the winch intermediate limit, according to the 2006 manual, with slowdown switches before each stop, as logged by the HIT SRL technical desk. The manual has a boom-angle encoder take over if a mechanical limit switch fails, as recorded at HIT SRL. According to the 2002 edition, the intermediate winch limits gave two under-hook height bands of 30 m and 23.5 m, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 200: how do the dead-man push buttons work?
Every crane manipulator in the cabin has a dead-man push button that must be held for any movement, according to the 2006 manual, the HIT SRL technical desk notes. The manual gives the portable radio console a protective frame against accidental use of the levers and forbids taping over the dead-man button, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 200: what do the emergency push buttons do?
They stop all movements and the main engine with rapid braking, without a deceleration ramp in the 2002 description, according to the manuals, as recorded at HIT SRL. The 2002 description gives two in the machinery room, one in each cab, one on the chassis and one on the portable board, and a pressed button stays locked until turned clockwise, with the engine unable to restart while any is pressed, as logged by the HIT SRL technical desk. HIT SRL service technicians report that the emergency push buttons work on MHC 200 cranes in service as the manuals describe; their positions are those of the manual of the specific crane.

Only with the turret stopped and locked, according to the 2006 manual, which states that the chassis platform has no guard rails and is not a working position, as set out in the HIT SRL technical cards. Access follows the manual of the specific crane, which keeps everyone out of the machinery and winch rooms during operation, the HIT SRL technical desk notes. HIT SRL service technicians report that the machinery room and the winch room must stay empty while the crane is working.

In the parking area, on stabilisers, with the slewing lock pin checked and the boom raised with only the hook block, according to the 2006 manual, as HIT SRL's technical desk reads it. The manual then stops the engine, locks cabin and machinery-room doors, disconnects the batteries for stops longer than two days and uses quay power and earthing where available; with very strong winds forecast, boom or boom and tower are lowered according to the wind table, as recorded by the HIT SRL technical desk. On a given crane, the wind table for parking is the one in its own manual.

Not completely: opening a box isolates the 380/220/110 V supply through a safety device, but the 24 V supply remains live, according to the 2006 manual, as set out in the HIT SRL technical cards. The manual allows only qualified electrical staff to access the boxes, as recorded by the HIT SRL technical desk.

Fantuzzi Reggiane MHC 200: what does the display show about the greasing system?
Its state, active, waiting, blocked or off, according to the 2006 manual, the HIT SRL technical desk notes. The manual warns that lack of grease can seriously damage the slewing bearing, the boom-to-tower hinge and the luffing cylinder, as set out in the HIT SRL technical cards. The same manual has the system go to blocked if a cycle exceeds its time limit, the grease tank is low or the pump motor thermal cut-out trips, as recorded by the HIT SRL technical desk.

One trained person directs crane movements with an agreed signal code, according to the 2006 manual, and load equalisers are required when the angle between rope legs exceeds 120 degrees, as HIT SRL's technical desk reads it. The manual keeps everyone from under a suspended load, guides loads only with tools and uses a signaller when visibility is insufficient, as recorded by the HIT SRL technical desk.
