Website: www.integralequipment.ca
Type of Carriage: Grapple
Engine HP: Hydraulic Power
Skyline Diameter: ⅝-inch to 1-¼-inch (Mainline Diameter: ⅜-inch to ⅞-inch)
Grapple Opening: 6 feet, 10 inches
Load Capacity: 7,700-9,900 pounds
Integral Equipment supplies the Alpine Shovel Yarder and Alpine Grapple Carriage to North America. The Alpine product line has been thoroughly tested globally and locally. Alpine grapples can be installed on multiple yarders.
The AGC2 has the closing power of a Johnson-style grapple, which uses the mainline to close. Combined with a multi-directional pump to provide hydraulic power for rotation, closing line and mainline brakes, there is no need for an engine, so there is less maintenance and more uptime.
The grapple open and 360-degree rotation functions are hydraulically powered and controlled via remote electric signals. Hydraulic energy is stored in accumulators and pressurized by a pump, connected to one of the haulback/skyline sheaves, as the carriage travels along the cable. Multiple cameras on the grapple and optional lights increase efficiency.

The Hawkeye motorized grapple carriage manufactured by New Zealand-based was developed to work with the Harvestline hydraulic mobile yarder. The Hawkeye and Harvestline share the same display screen, reducing the number of screens in the cab. The MK4, a new and improved model of the Hawkeye, will be released in 2023. The MK4 Hawkeye will be equipped with an upgraded 3 cylinder diesel engine and a new variable displacement hydraulic system that increases open and close cycle times and grapple clamping force and reduces hydraulic heat. Other improvements include fewer electrical components and less wiring and increased access to the inside of the carriage for maintenance.
The MK4 Hawkeye is equipped with a 68-inch grapple and features 360-degree continuous rotation, an auto clamp feature for closing the grapple, and work lights. Three cameras give the operator a view of the grapple as well forward and rearward views. The MK4 Northwest model will be a lighter weight, increasing payload to the landing.
