Differences between bridge and gantry cranes' downtimes [PDF]
Maintenance is especially crucial when it comes to construction machinery due its capacity to avoid or reduce the risk of serious accidents by recognizing probable failures and down times in a timely manner. To properly implement maintenance strategy, it is required to identify the existing linkages between downtime and failures that have already ...

A pragmatic controller for a gantry crane
Abstract A gantry crane presents a control problem with ten state variables. The undamped swinging of the load has led earlier researchers to apply cumbersome control strategies. The essence of pragmatic control is gleaned from autopilot designs of half a century ago.
