Improve Workforce Efficiency

Course #: 286016
Duration: 10 hours
What Students Learn: The purpose of this series of study units on rigging is to tell you where and how to stand, to tell you about the basic tools that are available, and to show you how to use the tools to move heavy or awkward objects in a safe and efficient manner. In short, the purpose is to help you understand the basic principles of rigging you'll need in your daily activities on the job.

This first study unit in the rigging series presents an overview of rigging - what it is, what kind of work is involved, who does it - and provides you with a fundamental knowledge of the basic mechanisms used in rigging and of the concepts of mechanical advantage, friction, center of gravity, and weight. Recognizing that the metric system of measurements is widely accepted, we've provided an Appendix which gives metric conversion factors for the English system units used in this text.

Course #: 286018
Duration: 10 hours
What Students Learn: In this study unit, you'll study some of the basic tools and pieces of equipment that are used in typical rigging operations. This unit deals with wire and fiber ropes, and chains. In particular, you'll study about the characteristics and requirements of these common rigging and hoisting tools, and about the procedures and precautions required in their use. Also included are inspection methods, rope splicing, and fiber knot tying.

In the selection of tools and rigging equipment, it pays to obtain quality items. Also, before using any tool or piece of equipment, the rigger is cautioned to become familiar with its operating characteristics and limitations, and the proper handling techniques and required maintenance for the tool. The more complex the tool or piece of equipment, the more certain the rigger should be of its characteristics.

Course #: 286019
Duration: 10 hours
What Students Learn: In this study unit, you'll learn how riggers use simple and complex rigging tools to complete a task. This unit explains how slings, hitches, hoists, and various other types of rigging hardware are sized, selected, inspected, and positioned by riggers as they prepare to lift a load. You'll learn how to combine the reeving hardware you've already learned about into safe, effective reeving systems. You'll be introduced to the types of equipment riggers use to move a load along a floor or roadway and learn how they support these loads. This study unit includes an overview of wood grading and inspecting practices. Many riggers must be able to select wooden supports and other items used during lifting or supporting operations. Finally, the unit ends with an in-depth discussion of ladder and scaffold types and specifications.

Course #: 286020
Duration: 10 hours
What Students Learn: In this study unit, you'll learn about cranes and other types of equipment used for heavy lifts. This study unit isn't intended to make you a knowledgeable equipment operator, because every manufacturer's equipment is different, and specialized training on specific types of equipment is always necessary. Rather, the unit is intended to make you familiar with the range of equipment available in the marketplace and help you understand the benefits and limitations of each category of lifting equipment. Some of the more widely used pieces of equipment are described in additional detail so that you'll know more about their inner workings and operation.

When you complete this study unit, you'll be able to:

Course #: 286021
Duration: 10 hours
What Students Learn: This study unit continues the review of lifting equipment. In Part 1, we focused on small lifting equipment (hoists, aerial work platforms, and lift trucks) and on various types of mobile cranes (crawlers, truck-type, floating cranes).

In Part 2, we describe the remaining types of equipment, grouped simply as limited travel cranes, derricks, and specialty cranes. We then present a series of case studies that show how some of the lifting equipment we have studied are actually used in the workplace. The emphasis is on particularly challenging or noteworthy lifts. When available, we have also included information on the rigging techniques employed for these lifts.

After reviewing Lifting Equipment and Applications, Parts 1 and 2, you should have a good general understanding of the range of lifting equipment that you, as a rigger, will encounter at industrial and construction work sites, how this equipment works, and the advantages and limitations of these lifting devices.
