| Capacity from 10 MT to 500 MT |
| AMINsTraversing Rotators (Conventional / Self Aligning) follow the well established reputation of their static counter-parts for ease of use and reliability. We are providing an economical and practical platform for all cylindrical vessel rotating problems. |
| Conventional Rotators are built in capacities from1T to 2000 tonnes. The frame is of robust fabricated construction and is machinened on the top and underneath to ensure perfect alignment. Both the drive and the idler frames are provided with robust fabricated and machined wheel brackets which support the axles and bearings of the rollers. According to capacity theRotatorsare provided with all rubber tyres, or Polyurethane tyres and separate all steel overload wheels, or can be of course be supplied with cast steel wheels. TheRotatorbase fabrication, or chassis, is designed and fabricated to carry the weight of the vessel / Job and incorporates a contingency for shock loading. It is important that the design eliminates any distortion which can lead to misalignment of the rollers. The drive section comes under the biggest strain when the vessel /Job is being loaded. It is physically impossible for a crane operator to position the vessel so that it contacts with both sets of rollers at the same time. If the work-piece one roller before being supported on all the rollers, the first roller will receive a full shock load which puts a considerable force on to the drive. We have endeavored to incorporate a good overload margin to absorb this shock load. |
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.
