The RotaChock is an innovative steel chock to be placed under machinery or engines that need accurate alignment, such as ship’s engines, presses, pumps and lathes. The RotaChock element can be readjusted at any time if necessary.
RotaChock benefits when compared to other procedures or products:
Speed. A RotaChock is installed quickly. A machine set up on a RotaChock can generally be realigned and secured within one day. In comparison: using epoxy resin chocks, it takes at least three days for the machinery to function again, due to the resin\’s relatively long curing time. Making traditional steel filler elements takes even longer, and labor cost make it fairly expensive.
Optimum contact surface. The RotaChock has a spherical bearing that ensures the best possible contact surface, even if the foundations and the machine foot are not parallel. In addition, the RotaChock is height-adjustable. The combination of these two features avoids “soft foot”, the situation where the foot of a machine or equipment does not properly link up to the base it is mounted on. Parallel soft foot and angular soft foot are the most frequent causes of poor alignment.
Any desired torque. The RotaChock\’s behavior is that of a solid steel chock, and the RotaChock allows the foundation bolt to be tensioned to any required torque. Epoxy chocks, in contrast, have a maximum load of 3.5N/mm2. This relatively low load often result in bolts that are almost loose.
High loads. RotaChock\’s competitive edge is that it has a big footprint: the surface area of the lower ring that is in contact with the foundation is greater, so the pressure exerted on that surface is less. The RotaChock also uses non-metric screw threading. Studies have shown that this allows the RotaChock to take 1.5 to 2 times greater loads. As a result of the reduced pressure at the surface and the higher loads, a chock with a smaller diameter than usual can be used.
