AERIAL TREE TOPPER

MODEL CS-1-TT

Purpose:
To remove tree tops in seconds, in second growth timber that has been previously logged, in an effect to reduce blow-down along prevailing wind exposed areas.  Reduces the crown to make air transitions through the timber stand easier.

Method:
The “TOPPER” is designed with an upside down cone, to be lowered 15FT over the tree top.  Once the desired depth has been reached, the TOPPER is stabilized by the helicopter.  A shuttle is activated by the pilot to advance a single saw blade through the tree trunk, forcing the top of the tree to fall away.  The shuttle is moved to open position as the TOPPER proceeds to the next target.  Starting, stopping and the shuttle are controlled by the pilot through a wiring system linked from the TOPPER to the aircraft.

Data:
20H.P 4 cycle engine; clutch– centrifugal; blade-single 33” dia. Shuttle; electric over hydraulic, 30” to 40” stoke.  The hydraulic system is activated by a built-in battery that is kept charged by an alternator attached to the engine, which is installed on the TOPPER.

Direction of Fall:
Is controlled along power lines, streams etc., by means of a spring loaded bar (arm) mounted in the front section of the TOPPER which will tip the top forward when it is cut.

Benefits:

• 120 to 150 tops cut per hour

• Efficiency  - half the cost of a crew

• Safety - eliminates risks to crew

• Clean Cut Top - at an angle to help prevent disease to the tree

• Single Lifting Point - effectively reduces tree top hand-ups after being cut

• Will cut 12” in dia. at an angle, saw cut to prevent damage to the standing stem
