Silvey Tree Jacks

Logger's require accurate falling so their machines can move logs efficiently. Environmental requirements make is necessary to fall trees away from streams and other sensitive areas. Logs that break because a faller misses his lay, cost landowners money. All of these factors make it necessary to fall trees accurately. When it was in production, the Silvey Tree Jack was a tool that helped timber fallers meet these challenges.

Silvey jacks are no longer made, but parts are still available, and we still offer service and repair. The main components are no longer available, but we have seals, springs, gauges, fittings, and most parts that wear or can be lost.

The White Crew Falling a Tree

Shown is a Silvey Tree Saver being used to direct the fall of a big fir. A seat for the rams was cut by the faller prior to their placement in the tree's base. The rams are connected via hoses to the pump unit shown on the left in the foreground.
