Travelling gantry crane with suspended mass
2000Here we must achieve a model, in order to regulate both the freedom degrees of a travelling gantry crane composed of a mass truck M, moving according to the x axis under the action of an F force and m mass suspended from a 1 long cable. The m mass oscillates from its cable with a θ angle in relation to the vertical attached point.

Digital passive teleoperation of a gantry crane
2007 IEEE International Symposium on Industrial Electronics, 2007Gantry cranes still pose a control challenge, mainly due to the problem of load swing suppression in under-actuated conditions. In the teleoperation setup, the operator-master dynamics and the transmission delay complicate the overall system design. Fortunately, the framework of passivity theory offers the necessary resources to address this problem ...

Simple anti-swing feedback control for a gantry crane
Robotica, 2003We propose a simple quasi time optimal control law for a gantry crane with a payload. The force applied to the trolley is a controlling parameter. The control law consists of two parts: a feedforward term and a trolley position and velocity feedback term.Initially, we synthesize the feedforward term and the corresponding reference trajectory by ...

Control-based damping of elastic gantry crane vibrations
2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR), 2017In this article control-based reduction of gantry crane elastic swinging in the trolley travel direction is concerned. As acceleration forces of the trolley are often the reason of these vibrations, they can be utilized in an appropriate damping strategy. For an elastic crane a dynamic model is derived applying the finite element method (FEM).

Crane rigger/spotter run over by mobile gantry crane. [PDF]
, 2003 On May 15, 2002, a 44-year-old male rigger/spotter was fatally injured when he was run over by a mobile gantry crane at a concrete plant. The victim had worked at the plant for three years and was employed as a rigger/spotter for a large mobile gantry ...
