Lectures

  • Semester 6, position 4

Goal

The basic goal of this subject is to introduce students into the fundamentals of intralogistics (material handling equipment in intralogistics) and to enable achieving practical skills in engineering education and professional work such as are analysis of duty cycle of material handling equipment, selection, sizing and calculation of material handling equipment as elements of material handling and conveying machines.

Outcome

Upon successful completion of this course, students should be able to: • recognize and describe the elements for lifting loads • choose handling device according to the sort and characteristics of material • determine the duty service classification of cranes and driving mechanisms • perform calculation and selection of elements of hoist mechanisms • perform and selection of elements of travelling mechanisms

Theoretical teaching

Introduction into intralogistics and material handling equipment, significance of this field, historical development, classification, types and shapes of materials which have to be handled, application groups, classification into application groups. Elements of driving mechanisms (selection, sizing, calculation), ropes and chains, load handling attachments(hooks, triangular hooks, pulley blocks, slings), sheaves, drums, brakes and arresting gears. Mechanisms for lifting, hand operated hoisting devices (screw-type jack, rack-and-lever jack, hydraulic jack, lever hoist, chain hoist, rope hoist), crane crabs for unit, piece and bulk loads (crane clamps and grabs, carrier beams, electric lifting magnets, vacuum lifters, grab buckets, spreaders), hoists with electric motor, calculation of mechanisms. Mechanisms for translational movement of trolleys and cranes, resistance to motion, wheels, rails, slipping, braking, calculation of mechanism.

Practical teaching

Video presentations of machines and principles of material handling equipment operation as well as hoists and cranes. Determination of application groups for hoists and cranes, based on the load spectrum. Calculation of the elements of the drives, calculation of force in rope and chain in slings and pulley blocks. Calculation of drums and shoe brakes. Calculation of lifting mechanism, selection and adoption of application group. Calculation of mechanisms for translational motion, the selection and adoption of application group, calculation and defining the diameter of wheel and rail, checking security against slipping. Laboratory exercises on the computer, 3D modeling of material handling equipment in CATIA software.
