SLRS - Specimen lifting and rotation system
Manipulation of stiffness specimens of 3000 mm diameter and greater requires more than one operator for handling specimen during loading and testing and poses a serious risk hazard. For example, a 4 meter pipe stiffness ring has a weight exceeding 400 Kg, a slenderness ratio greater than 13, and a center of gravity 2 meters high. The handling of such specimens poses serious safety risks. To address this hazard, YLE developed the Specimen Lifting and Rotation System (SLRS) which is incorporated as standard in CK4400 machines and is offered as an option on CK3200 machines. In addition to addressing safety concerns, the SLRS provides improved user-friendliness and productivity.
A CK4400 with SLRS won the Innovation Award of the 2014 Shanghai Composites Expo.
