New Tigercat EHS skidder drive
MAY 23, 2013, Brantford, Ont. – Tigercat is continuing to develop and refine its skidder product line, its latest technology is the EHS drive system.
Similar to the hydrostatic drive system that Tigercat developed and released in 1996 with the first 630 skidders, EHS consists of two variable displacement motors as inputs to the Tigercat transfer case. Front and rear output shafts are connected directly to the front and rear axles.
The EHS is capable of providing the tractive effort of the deepest gear ratio offered in Tigercat's standard transfer case as well as the top speed of the shallowest gear ratio offered in the standard transfer case.
This is accomplished with sophisticated computer logic and the ability to take one of the drive motors offline when high tractive effort is not required. In this case, all pump flow is directed to one hydraulic motor, increasing both travel speed and motor efficiency.
When operating conditions demand high tractive effort, both hydrostatic motors are working. When tractive effort requirements are minimal, all of the pump flow is directed to one motor for higher travel speeds.
Tigercat is offering EHS standard in the 610C and the new 615C and expects end users to see higher productivity and improved fuel efficiency in the majority of applications.
