Heavy-duty vine and tree shears - is battery-driven via solenoid Bowden cable and reduction gear

摘要

The vine and tree shear is for hard continuous use, having driven blades, the drive to which is taken from a mobile unit with a battery and solenoid via a Bowden cable to a reduction gear on the shear. A detector on the shear emits the electrical release signal to the solenoid via the Bowden cable. The battery can be 12 volt 102 ampere-hours capacity, and the reduction gear can be designed to increase the force exerted by the solenoid of 40 kg to 400 kg at the shear blades, being of the mechanical type with levers.
