Tethered Harvesting Machinery Demonstration Day

The forestry industry globally has a significant challenge when it comes to ensuring worker safety. Whilst significant strides have been made over the last twenty years with the advent of mechanised harvesting technology the accident rate amongst chainsaw and winch operators still remains at unacceptably high levels and is amongst the highest of any industrial sector.

In order to address this issue the global industry is seeking to increase the degree of mechanisation of timber harvesting operations and significant efforts have been made overseas, principally in New Zealand and Central Europe, but also latterly in North America to utilise new technology to achieve this.

The principal limitation to increasing the amount of timber harvested by mechanised means is the current slope limitations that existing mechanised machinery is constrained by.

In order to increase the terrain capabilities of existing harvesting machinery the forestry industry has begun to develop tethered winches which provide additional traction to timber harvesting machinery and thereby increase the degree of slope on which conventional machinery can operate.

Although this technology is in its infancy in the UK a number of winch systems for use on steep terrain have been developed overseas.

In order to increase awareness of these technological innovations within the UK and also to begin developing operational protocols to cover the use of these developments Tilhill Forestry is organising a tethered harvesting demonstration day in South Wales on Tuesday October 4th.

On display at this event will be two tethered harvesting machines.

The T-Winch is a traction winch system which has been developed in Austria by Ecoforst. The T-Winch is a self-propelled traction winch which has 500m of cable incorporated within it and allows a conventional harvesting machine to be attached to the machine to increase the traction available to the tethered machine and increase the slope angle on which the tethered machine is safely able to operate.

The CEO of Ecoforst – Markus Krenn – is a timber harvesting contractor in Austria who saw the benefits that a greater degree of mechanisation offered and developed the T-Winch to enable this. The T-Winch has been in the development stage for over 5 years, but has only been in commercial production for the last 18 months, so it is a new development, but one that promises significant potential benefits to the industry, both in terms of operational safety improvements, but also additionally reduced ground damage.

Despite this being a very recent development the T-Winch is currently operating with a number of timber harvesting gangs in Central Europe and there is additionally six T-Winches operating in the forestry industry in Chile. Markus also has strong interest from North America and Markus will be across at the Maple Ridge forestry show in British Columbia demonstrating the T-Winch immediately prior to attending the event in Wales.

In addition to the T-Winch a tethered Kaiser walking excavator with a set of tree shears will be demonstrated at this event.
