Cylinder alignment monitoring system for a mast or derrick
A cylinder alignment monitoring system for a mast or derrick hingedly connected to a substructure wherein at least a pair of extending cylinders move the mast or derrick between a storage position and an upright use position. The monitoring system includes a distance measurement device to determine the extension distance of each of the extending cylinders. A comparison device compares the extension distances measured for each of the extending cylinders.
