| Detailed
description of topics: Lay-out and operation of bulk- and containerterminals. Filosophy
of mainports. Data and maindimensions of cranes, specification of crane cycle time.
Flowsheet of engineering process. Several configurations for main
lay-out of gantry cranes. Strength and stiffness, specification of forces. Second trolley
system.
Design concepts of backreach, frontreach as central bridge(s) of the
crane. Support of frontreach and backreach, several box-type frontreaches. Connection
between front reach and foreleg of the crane.
Several types of cable-trolley systems. Trim, list and skew
facilities, sag of hoisting cables, loss of energy and internal forces due to type of
cable-trolley system. Dynamics of hoisting operation and trolley travelling. Suppress of
swing of the load. Choice of type and optimisation of the front reach lay-out of gantry
cranes on base of selection criteria.
Types of crab cranes, lay-out and properties of hoisting cable
system. Analysis of forces in crabmechanism, drive of closing and hoisting movement.
Several types of single and double luffing cranes, kinematics and
forces due to luffing operation, balancing of mass, optimal design, energy efficiency.
Detailed design of some crane parts.
Physical basics of wind, characteristics at sea and inland, static
and dynamic windforces on cranes, relation with engineering standards. Von Karman effects
and vibrating excitation of construction parts. Concepts to avoid vibrations.
Engineering standards. Definitions, specification of hoisting and
goods handling equipment as related to lifetime and character of crane operation.
Specification of forces on the construction, calculation methods.
Types of welding connections of steelplates, concepts to support
rails on outreach and bridge beam(s).
Crack of bars, basics and engineering standards, crack of compound
bar constructions.
Properties and choice of cables, guiding wheels and cabledrums.
Support of gantry cranes on rails using several wheel units.
Rail-wheel contact, forces between rail and concrete.
Calculation and design of box girders.
