  A number of static solutions of the triangular running skyline system (TRS) are introduced in this report. The TRS is a logging cable system that enables the carriage to be moved three . People | UBC Faculty of Forestry. Two compacted steel wire ropes for cable logging have been introduced in Norway. Compacted wire ropes were introduced mainly because of their longer life expectancy; a mechanical treatment to increase the metallic cross-sec- tional area results in a higher strength-to-diameter ratio. (This may, for example, include a swaging process wherein the rope .

The minimum factor of safety generally used by logging engineers is 3, although the tables in the wire rope manufacturers' handbooks use a factor of safety of 5. A factor of safety of 3 means that the tension is one—third of the Tension .

Little effort has been directed, however, toward field measurement of cable tensions for skyline logging systems to facilitate initial tensioning of unloaded skylines or to provide means of field checking to see whether skyline systems are overloaded.

The two surest methods of preventing overloads are to have continuous-reading tension. Cable yarding systems handbook. –– – Irregular “WorkSafe.” ISSN = Cable yarding systems handbook 1. Logging – British Columbia – Safety measures.

This book on wire ropes is dedicated mainly to all users of wire ropes – the construction engineers, operators and supervisors of machines and instal- tions running on wire ropes – and it is divided into three main sections. The?rst section deals with the di?erent types of wire rope and their component parts, the second looks into the e?ects of wire.

Armor (usually a metal) is frequently applied over the cable core to provide this protection. The armor extends the life, while improving the reliability, safety and performance of the. I've used an E=12, ksi and an effective area Ae=Ag which approximates the midrange of values listed in the Wire Rope Engineering Handbook.

I've used a 1" diameter cable. Introduction This handbook focuses on skyline yarding as the most common type of logging operation in Oregon, assuming steep terrain and use of a yarder tower and cable system. Basic information may.

As an example, experimental tests that measured tensile forces on the skyline of a cable logging system during real working cycles, showed peak values up to kN during lateral skidding.

The types of wire, lay and performing greatly affect wire rope performance and operation. In this reference document (an excerpt from the Wire Rope Users Handbook), you will learn the basic types of wire used in ropes, the common grades of wire rope and the meaning of “lay”.

It is the responsibility of the Services Contractor to provide the logging winch unit, together with sheaves, tool house, explosives and radioactive stores, in order to carry out the wire-line logging.

Tension stretch relationship of wire rope.-Wire rope is used for the guyline material. Within its elastic limits, up to 65 percent of the cable breaking strength (Broderick & Bascom Rope Company ), the stretch in a guyline, AS, caused by a tension, T, obeys Hook’s law:’ TR AE AS=-- orAS=- T.

If | Find, read and cite all the research. The skyline is the centerpiece of every tower yarder and long distance ropeway.

Skylines from TEUFELBERGER are developed and tested in cooperation with original equipment manufacturers (OEMs) These collaborative efforts and joint field tests ensure the consistent quality of our steel wire. Maximum skyline tensions vary f to 80, Ib depending on the size of the logging machine.

System response to loading is complex because of nonlinearities due to cable behavior, beam-column loading of the spar, and the geometric effects of large spar deflections. WIRE ROPE % FIBER ROPE 50 % FIBER WEBBING % CHAIN CAPACITY IS POUNDS X.7 X = POUNDS.
