    Putting the Equipment to the Test Sutherland runs two sides, both cable logging because of the steep slopes. And, Sutherland chooses to use a running skyline versus a standing skyline with a motorized carriage. “The cable logging pays more,” Sutherland says. On the flip.   Edit: Make your slopes much longer than needed in the editor. I would go a couple of units past the point when it stoppped giving me the "Slope too steep" message for the flat editor ground and this seemed to help for the uneven game ground. Hopefully a better slope . The steep terrain in the area brought Speers yet another operation. Where conventional logging just wasn’t practical, cable logging became the process of choice. Logs are lifted off the ground by suspended cables and winched to the yarder. As no mechanical equipment is utilized on the steep slopes, ground disturbance is kept to a minimum. matched to steep slopes. The B is equipped with Tigercat bogies that are well proven in severe duty six-wheel drive skidder applications. Tigercat’s unique WideRange™ transmission allows travel at speeds up to 7 km/hr ( mph) with tractive effort suffi cient to carry 20 tonne (22 ton) loads up 60% slopes.

Oregon OSHA Yarding and Loading Handbook. Introduction. his 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 also apply to other logging methods. The material in the handbook is intended to reinforce. and workers logging with cable yarding systems.

Readers may use it on the sidehill, in the bunkhouse, or in the office. WorkSafeBC also uses the Cable Yarding Systems Handbook in training its own occupational A test of skyline cable logging on steep slopes book officers. This handbook does not replace the Workers Compensation Act and Occupational Health and Safety Regulation; rather, it supplements it by providing examples of safe work procedures.

process. Planners and lay out crews working on steep slopes must consider harvest methods other than mechanical (e.g. cable system, helicopter, track-based versus rubber-tired, etc.) and, where practicable, designate those systems rather than building plans that would unnecessarily compromise employers’ ability to ensure machine Size: 1MB.

Yarding Cost for the Koller K Cable Yarder: Results from Field Trials and Simulations Neil K. Huyler, USDA Forest Service, Northeastern Forest forested slopes is the use of cable logging technology. Cable contained steep slopes to be harvested with the Koller K yarder. The mean slope for the area was approximately 40 to.

For the test tract, Eric ended up bringing in the other LSC and shovelling the wood up to the landing. However, on steep slopes, uphill shovel logging becomes problematic after a couple of swings as the trees lose their branches.

“How do you keep the wood from flinging down the hill?” muses Eric. “I want to be fully mechanised and. Slopes of that type are generally logged with a cable yarder in North America. A main cable is rigged down the slope with a carriage that runs up and down the cable.

Attached to the carriage are chokers that are attached to the log, and the carriage lifts the log and then transports the log to the top of the slope. • Review of cable systems and skyline carriages • Logging around streams • Laying out a unit with unstable steep slopes Break Payload, Productivity and Efficiency • Skyline deflection – Safe working Loads • A test of skyline cable logging on steep slopes book that influence productivity • Understanding wire rope characteristics • Variables affecting skyline deflection Lunch (included with registration).

In MayNZ Logger Magazine Iron Tester Stan Barlow conducted a performance test on the Bryant logging owned Falcon Winch Assist in Eves Valley Nelson, N. Two methods for measuring cable tensions for skyline logging systems have been skyline size, skyline slope, and a midspan deflection of about 7 percent, the weight of log plus carriage cannot be greater Sample nomographs for cable diameters of 3%, 7/8, 1, and It/8 inches and skyline lengths less than 2, feet.

Enrol today, Or visit INNOVATIVE METHODS FOR STEEP TERRAIN HARVESTING Dzhamal Amishev, Tony Evanson Scion (New Zealand Forest Research Institute), 49 Sala Street Rotorua, New Zealand e-mail: [email protected] Keywords: Innovation, mechanised cable logging, steep slopes, felling and bunching.

2) To develop a model to simulate these relationships under varying working conditions of the skyline system and to\ud identify proposals for improved logging methods. I observed a cable-thinning operation on a year old Douglas-fir stand on gentle and medium steep slopes. This skyline cable logging machine is a small-log mover; cable is rigged from the short tower (’ tall) to the far side of the harvest area; a carriage rides the cable and connects to logs using additional cables; logs or small trees are lifted and carried on slopes from the stump to the roadside landing area; suitable for thinning.

Tethered logging systems are not new, having been utilized in New Zealand on the steep (and similar) terrain there. The systems themselves aren’t utilizing any dramatically new technology either. In tethered systems, a winch has been fitted to the back of a piece of equipment such as a harvester or a forwarder.

In logging talk, a skyline is said to be standing or running. A standing skyline is a cable pulled out from the yarder and tied off at the other end of the job. Other than the fact that you may adjust the amount of sag in the line, it doesn't move.

Ground-based equipment can become unstable on steep slopes, especially when turn-ing. Small obstacles such as windfalls and stumps that can be negotiated safely on lesser slopes may cause the machine to overturn. When skidding downhill with line skidders on steep slopes, the logs may run ahead into the machine, thus presenting a safety hazard.

BCFSC Steep Slope Resource Package - Version 2 Apr Last revised: 4/13/ AM Page 3 of 25 Introduction Operating logging equipment on steep slopes increases the likelihood of reduced machine stability, which can result in an upset, or roll-over.

Such events can result in serious worker injury or fatality, significant. LANDSLIDES AND DEBRIS FLOWS October A landslide is a mass movement of rock, soil, and debris down a slope.

In steep terrain, even a small mass movement can transform into a larger, especially dangerous type of landslide. These catastrophic landslides commonly are referred to as debris flows, mudslides, mudflows, debris torrents or shallow.

"Slope is too steep" happens in far too many places that it shouldn't be. Showing of 4 comments. Waz. @ am When you're building onto an existing road with a slope, the junction you create may make the existing section of the road too steep. Try flattening your existing roads a bit or building onto flatter sections.

Krume Logging cable assist trial Krume Logging tests its fully automated cable assist logging system. The Tigercat LSC shovel logger equipped with the directional felling head is felling and bunching on a 60% slope that steepens to 80% near the bottom of the slope.

This is just one small reason why I like making the longest ramps possible. In reality steep grades are avoided in roads unless the terrain absolutely demands it. So not only do longer, shallower ramps fit better to the terrain in-game, they also tend to look more realistic. The side effect of course is bigger, more expensive interchanges.

I took these for a test run this morning on my daily training hike through the woods, which includes steep slopes, mud, leaves, rocks, creek crossing and a log over a creek.

For this reason, there has been a recently growing interest in using cable yarders to harvest these areas. A computer simulation model was developed to aid in investigating the feasibility of cable logging on a particular site in the region.
