The Application of Kalman Filtering to Predict Vertical Rail Axis Displacements of the Overhead Crane Being a Component of Seaport Transport Structure

Polish Maritime Research, 2016
As the devices designed to transport materials, the overhead cranes should meet certain geometric requirements for their operation to be safe. The presently available geodetic equipment, in particular total stations, provides opportunities for precise 3D

First report on containers [PDF]

, 1966
Everybody agrees that containers are a "good thing";the actual advantages of transporting cargo, and in particular, dry cargo, in containers over other forms of transport have, to our knowledge, nowhere been stated in quantitative terms.

Optimal Manoeuvres of Underactuated Linear Mechanical Systems: The Case of Controlling Gantry Crane Operations

Journal of Applied Mathematics, 2014
A method of solving optimal manoeuvre control of linear underactuated mechanical systems is presented. The nonintegrable constraints present in such systems are handled by adding dummy actuators and then by applying Lagrange multipliers to reduce their ...
