  •  Hydraulic Elevator Performance.  Provided analysis of a hydraulically powered elevator at a multistory condominium facility on the  California coast in support of the manufacturer.  The case involved claims against the design and performance of the elevator system.
  • Forestry Mower Performance.  Analysis of the load induced on the prime mover engine by the hydraulic system for a compact track loader with a forestry mowing attachment used to cut and clear brush.  The work included measurement of system pressures developed and calculation of the power demand of the hydraulic system used to power the attachment.
  • Telescopic Handler (Rough Terrain Forklift) Injury.  In a case involving the death of an observer of an offloading operation at a construction site, provided analysis of the design and assembly of the four-axis controller used on the telescopic handler for the hydraulic system powering the boom.
  • Parking Lift Accident.  Analysis of the probable causes of an accident in which a hydraulic parking lift fell on the lift operator. 
  • Rolloff Trash Truck Installation.  Provided technical assistance to the purchasers of a rolloff trash truck body which was not installed properly.
  • Pipeline Padder Accident.  Analysis of the design of a machine used to pad pipelines with small diameter fill material during pipeline construction projects.  The padding machine was involved in an injury to a construction worker when part of the machine fell from its stored position and struck him. 
  • Towing Accident.  A heavy duty tow truck being used to tow a concrete pumper truck went out of control and damaged the towed vehicle.  Provided analysis of the load interaction on the stability of the tow truck.
  • Car Carrier Traffic Accident.  Provided expert assistance to the insurer of a towing company whose car carrier was involved in a traffic accident in which a passenger in a car was killed. 
  • Car Hauler Accident.  The operator of a covered tractor-trailer with hydraulically actuated lifts for hauling cars was killed when the loading ramp system fell and struck him.  Provided expert assistance in analyzing the hydraulic system for the trailer and identifying the cause of the accident.
  • Floor Jack Accident.  An injury occurred during repair work on a vehicle supported by a floor jack.  Provided expert assistance in determining the causes of the accident. 
  • Compact Loader Accident.  An injury occurred when repair work was being performed on a hydraulically actuated compact loader.  Analyzed the cause of the accident.
