Self Aligning Rotator

The design of the AMIN Self - aligning Rotators incorporates many hidden features, which are unknown to our competitors.
With the AMIN Self-aligning construction the trunnion brackets which support the rubber typed wheels automatically align themselves when changing from one diameter to another, no manual adjustment whatsoever is required.
Each section supports the vessel on four points ensuring better traction, and on machines of 3 T to 500 T capacity and upwards all four wheels of the drive section are positively driven. This four point suspension is an added advantage when on handling thin walled vessels.
The two top leading wheels of the drive section incorporate clutches which are loosened prior to  loading the vessel and the top wheels can rotate freely when the vessel is loaded; thus  regardless of weight if the vessel is lowered centrally between the frames, or firstly on to one  wheel only, no damage can be sustained by the transmission.
One problem in the welding of large diameter heavy vessels is the lining up of the  strakes. To facilitate this problem of lining up, the AMIN Self-Aligning Rotators can be supplied with an arrangement whereby the trunnion brackets which support the rubber typed wheels can be moved across the frame by lead screw so that the vessel can raised or lowered by widening the trunnion centers or bring them closer together and in addition a secondary screw adjustment can be provided to move both the trunnion brackets either side of the center line approximately 38 mm. 
In order to ensure that the four wheel point support can be maintained over an extended range of diameters the SAR. Frames can be supplied so that a spacer can be inserted in the main frame between the trunnion centres so that they are capable of handling vessels upto 11 metres or more in diameter.
