This course is the first offered by Elevator World where the study material is a DVD presentation. You can earn 3 contact hours (.3 CEU's) by viewing the presentation and completing the assessment exam online.
Approved for Continuing Education by NAEC for CET/CAT, by QEI Services and NAESA for QEI (maximum of 0.2 CEU for online courses per annual renewal period can be applied towards maintenance of qualifications for certified inspectors) and by the States of Florida, Arkansas, Kentucky, Pennsylvania, Virginia and West Virginia.
Learning Objectives - After reviewing the video, you should:
- Have developed a basic understanding of the principles of rope traction, specifically, that the amount of available traction between the suspension (hoist) ropes and grooves must always exceed the required traction to move the hoistway masses in a controlled and safe manner.
- Have developed a basic understanding that the amount of available traction between the drive sheave grooves and suspension ropes is a function of the actual coefficient of friction between them, the groove shape, and the arc of contact that the ropes make as they wind over the drive sheave between their entry and exit points.
- Understand that the major inherent safety feature of a traction drive is its ability to lose traction if either the car or counterweight bottoms on its buffer.
- Understand that the type of rope lubricant is important, and that it affects the available traction between the suspension ropes and drive sheave grooves.
- Have developed a basic understanding of the construction, terminology and characteristics of suspension (hoist) members, primarily steel wire ropes, and to a lesser degree, non-metallic ropes and coated steel belts.
- Understand that the number and size of hoist ropes on any elevator is a function of the strength of the ropes and the factor of safety, and that the groove pressures developed between the ropes and groove surfaces is influenced by several parameters.
