All structural components of our machines, especially the steel structure, are analyzed with software programs of finite element calculation. The structure is divided into countless small pieces,in order to analyze the stresses in all its parts; in this way, it is possible to know the points of the structure with the maximum values of moment and shear, the maximum stress and maximum strain and the structure is dimensioned accordingly.

 

This solution allows to realize structures that are shaped by following the trend of the moments and forces (dynamic loads applied); also allow the use of greater thickness where it is needed and smaller thicknesses where the material is less stressed, moreover this type of construction, plans to enter the internal baffles to increase the rigidity of the structure in particular in the way the points of application of the load.

 

The quality of steel used for each specific machine, is selected by our engineering department following UNI EN 10025 standards. The steel plates are supplied by first-class steelworks plants, accompanied by the related foundry certificates.

 

The frame has a single cross-member at rear and this “U” shape allows a wide variety of crafts to be accommodated. Box-beam structures are submerged-arc welded with an electronic and automatic control system; welders and welding procedures fully comply with

International Standards EN287-EN288. Box-welded sections are internally reinforced with diaphragms, to guarantee mechanical resistance, stiffness and side stability.

 

All joints are flanged with high resistance nuts and bolts; mutual position fixed with pins. Specific sealing that is applied during assembly phases prevent from water penetration.

 

A special extended rear cross beam, “U”-shaped and mounted behind the vertical axis of the rear piers, is included in this scope of supply. It provides additional clearance without the need for removing or adjusting the vessel’s rigging.

 

The proposed machine features an electronic steering system based on hydraulic Gearboxes drives. Each hydraulic motor powers a gearbox connected with a geared pinion which transmits the rotation movement to a big, teethed slewing bearing purposely fitted for this use; the rotation of the latter makes the wheels steering.

 

The whole gears and pinions system is completely encased in order to avoid sand and dirt to get in contact with this rotating part and also represents a safety feature during the operation and the maintenance.

The gearboxes are controlled by linear encoders and a PLC with proprietary software controls the position of each steering wheel-group.

 

1. Integral Self-Correcting Steering – (R/min ‹ Turning Radius ‹ ∞) - The lifting equipment can turn on the right or on the left with any possible turning radius starting from the minimum value, that depends only on the dimensions of the lifting equipment.

 

2. Rear Self Correcting - The lifting equipment can pivot (clockwise or counterclockwise) having one of the front wheels as the fulcrum of the rotation.

 

3. Front Self Correcting - The lifting equipment can pivot (clockwise or counterclockwise) having one of the rear wheels as the fulcrum of the rotation.

 

4. Crab - The lifting equipment can align all tires (on the right or on the left) along the same direction chosen by the operator and move along that straight line up to 45°.

 

5. Sideway or Transversal - (all wheels at 90 °) - The lifting equipment can align all tires at 90 ° and move sideways (on the right or on the left) along a straight line.

 

6. 360 ° - (Turning Radius = R/min) - The lifting equipment can rotate 360° degrees from the centre of the machine.

LIFTING POINTS

In order to get easier wrapping manoeuvres with slings, and avoid any contact with delicate shaped keel appendixes, helix axle, stabilizers and so on, the machine is supplied with n.6 lifting points / sling blocks adjustable hydraulically and n.2 fixed.

 

ASCOM sling blocks feature in-line pulleys, in order that the sling block does not ‘twist’ towards the boat when in the slings. Hoist rope pulleys are modular cast iron / reinforced

polyamide, turning on paired ball bearings that are prepacked with grease and sealed for corrosion-free and maintenance-free service.

 

- Ropes are calculated with a safety factor > 5

- Clamps are CROSBY-LAUGHLIN wedge types.

- Slings are in polyester with a safety factor = 7:1
