The hydraulic Riser Spider consists of a frame and sliding cassettes which slide along guide rails welded to the frame. The sliding cassettes include changeable inserts which are specific for each riser size. The Riser Spider can be locked in closed position by use of two manually operated mechanical locks. These locks will prevent spider to open even if unintended hydraulic activation occurs. System includes cover plate to avoid falling objects though the spider when not in operation.
