Turn your Excavator into a useful and powerful Skyline Universal Yarder
Zama Forestry Services, owned by Quinton Preen has invested in a tracked Hyundai excavator proudly supplied by HPE Africa. The excavator, which has been converted into a HT Shovel Yarder to cope efficiently with demanding uphill and downhill logging operations, in Mpumalanga was converted by Hintech Manufacturing.
Hintech Manufacturing, worked closely with HPE Africa, to transform the robust Hyundai R220LC-9S crawler excavator, into a versatile HT shovel yarder, for high-lead forestry operations, purposed for the extraction of logs.
“The 22 T Hyundai R220LC-9S excavator, which is the durable and mobile carrier of the HT Shovel Yarder conversion, has an impressive production capacity of up to 140 T per day, depending on the rigging, tree size and terrain conditions,” explains Alex Ackron, managing director of HPE Africa, exclusive distributors for Hyundai Construction Equipment in South Africa. “This fuel-efficient machine has a 300-m uphill or downhill operating distance and is able to extract up to eight trees simultaneously, with a payload of up to 3 T.
“There are many advantages of this customised forest harvesting solution, including fast cable yarding set-ups for increased productivity, easy mobility, precision control, low maintenance and important features for improved safety in steep, slippery and remote locations.
“The Hyundai excavator, which is self-stabilising due to its weight, provides its own anchor support, eliminating the need for guy lines. Unlike conventional cable yarding systems that are anchored, this tracked machine is able to self-travel between felling areas and manoeuvre over arduous and moderately steep terrain. Apart from providing extra stability and supporting the tower, the bucket is also used to clear debris on site.”
The Hintech fitted forestry spec all-weather steel operator cab is spacious, with glass windows on all sides for clear 360˚ visibility and a fully adjustable suspension seat– important features for enhanced operator comfort and improved safety in forest harvesting.
The advanced operator cluster, with a colour LCD screen and toggle switch control, allows the operator to select machine preferences during logging operations. These options include boom or swing priority, power mode, machine diagnostics and optional work tools. A computer aided power optimisation function automatically selects the ideal hydraulic flow balance for boom and swing motions, smooth operation and reduced fuel consumption.
The operator easily controls winch spooling from the cab, using haulback and mainline pilot operated joysticks and foot pedals which are conveniently mounted. A multi camera system for operator and offsite winch control and choker monitoring, is an additional safety feature of this machine.
Ground-line access to critical services and grease points of the excavator, ensures easy serviceability and reduced maintenance time.
“Hintech’s skilled engineering team is able to custom convert and reinforce every Hyundai machine to meet exact forest performance requirements, using proven systems developed in-house over the past 15 years”, confirmed Karl Hinteregger, owner of Hintech Manufacturing, a seasoned professional in the SA forestry sector for over 30 years.
