Crane Cylinder Selection Data
A crane cylinder transfers force through a moving structure. The cylinder bore is only one part of the selection: boom or jib geometry, load moment, speed and stopping behavior determine the forces seen at the rod, barrel, pins and support frame. Different crane layouts require separate calculations.
Design and installation review
Supply the minimum and maximum pivot distances, stroke, mounting style, rod compression length and load cases. Check alignment throughout travel, pin bearing pressure, hose movement and the need for load-holding valves. Position sensing or end switches should be defined from the control function.
What to include in an inquiry
State working pressure, duty cycle, ambient conditions, fluid and required test evidence. The final drawing should identify interfaces and service clearances, and the load-control method should be commissioned on the complete machine.

Configuration, dimensions and performance are confirmed against the approved project drawings; this section is specification guidance rather than a fixed catalog rating.
Project-Specific Configuration
Final technical parameters are confirmed after drawing review and operating-condition evaluation.
