Description of the equipment
The shipyards usually produce very big blocks, pre-assembled for the construction of the ships.
Such construction method was gradually adopted in order to achieve a stable and highly efficient work process, thus minimizing the ship’s delivery times.
This type of gantry crane, very big and with high carrying capacity, has been used for more than 10 years now.
PAOLO DE NICOLA has carefully studied the needs of the shipyards, specializing, in particular, in the design, fabrication and installation of machines that are sure to satisfy every Customer’s peculiar requirements.

BRIEF DESCRIPTION OF THE CHARACTERISTICS OF “CANT. NAV. F.LLI ORLANDO” GANTRY CRANE
The 360 ton. gantry crane supplied to Cantieri Navali F.lli Orlando of Leghorn (Italy) consists essentially in two main carrying beams, supported by a fixed leg on one side and a hinged leg on the other side.
The crane, movable on rails, is 73 m high and 95 m wide. The two main beams serve as runways for the winch-carrying trolleys. A set of 32 wheels makes the crane roll on the two rails at a speed that ranges from 0 to 30 meters per minute.
 The hoisting capacity of the top trolley is 240 ton while the lower trolley’s capacity is 120 ton, hence the crane has a total hoisting capacity of 360 ton.
Hoisting speed ranges from 0 to 6 meters per minute (when a load is being handled).
4 clamps ensure the crane’s anchoring to the rails under strong wind gusts.
A service elevator has been installed along the fixed leg and can easly and quickly transport up to 4 persons. The electric board room houses the Master PLC logic board and the supervision PC. The crane is controlled and commanded from a cabin suspended to the main trolley. On the top of the fixed leg an ancillary jib crane has been mounted to service the maintenance of the two trolleys.
A CCTV system, complete with monitors installed in the cabin, enables the crane’s operator to have a complete visual control over the rails in the four translation sides.
