Objective: Describe preventative maintenance proceduresĪctivity: Identify maintenance tasks and frequencies for hydraulic cranesĪvoid 'run-to-failure' with good maintenance and planning Day Two: Mechanics Theory and Design Think before you act - a few hundred PSI (or less) can injure or kill! Preventative Maintenance Objective: List common hydraulic hazards and safe procedures Objective: Explain outrigger circuit functionsĪctivity: Fully analyze the critical function of the lock valvesįind out how important clean oil is to keeping a crane upright Safety Objective: Explain valving and safety features to lift and lock the boomĪctivity: Trace out flow and pressure controls for the boom lift circuitįind out how critical it is to keep the fluid clean Outriggers Keep the slewing circuit in top condition Boom Lift Circuit Objective: Explain slewing circuit functionsĪctivity: Identify slewing components for normal function and boom dolly towing Learn about features that prevent runaways and excessive line pulls Slewing Circuit Objective: Explain the feature of typical crane winch circuitsĪctivity: Identify typical crane winch features on the schematic Day One: Operators & Mechanics Winch Circuits This two-day course is taught with circuit simulation software, typical crane schematics, and through instructor guided hands-on study of individual hydraulic components.

Safety is stressed along with sound maintenance and reliability practices. The Ten Step Troubleshooting Process is taught with the goal of eliminating the hit and miss methods. Analysis and troubleshooting skills are taught with schematic simulations from typical mobile crane systems. Participants come away from this highly concentrated course with a solid understanding of hydraulic principles and component functions. This course is designed to be the first step in rigorous hydraulics training for mobile hydraulic crane operators and maintenance personnel. Trained technicians and operators make all the difference in ensuring reliability and long system life. Hydraulic systems are safety critical on cranes.
