Pezzolato TB900/TM1200

Cut and Split
________________________________________
The wide availability of large diameter logs, not suitable to be processed by the sawmill industry, brought the company Pezzolato to develop a new equipment for high quality firewood by processing logs with diameters even larger than 1 meter (3′ 3.37”).
This equipment is divided in: TM 1200 CUTTING UNIT with a conveyor system to cut logs of any type.
The machine presents a large thickness of 30 mm (1.18”) feeding cradle which can support logs with a length of 6 meters (19′ 8.22”) (longer on demand) and a max. diameter of 1200 mm (3′ 11.24”).
The logs, by means of a rear pushing unit, are pushed onto the chain saw unit and blocked there before being cut by a hydraulic guillotine system.
The chain saw unit, sliding vertically, is driven by an electric motor with a power up to 22 kW (30 hp).
A step-measurement system allows the electronic setting of the cut logs length. After the cut, a tilting surface, hydraulically moved, skids the cut logs on the feeding chain of the second unit, TB – SPLITTING UNIT.

TB SPLITTING UNIT is equipped with an automatic vertical splitting system, able to process any type of logs, with a diameter range varying from 300 to 1200 mm (from 11.81” to 3′ 11.24”) and a maximum heigth 500 mm (19.68”). Diameters under 300 mm are allowed for firelighters production, according to the length, that could reach a minimum of 50 mm.
This unit conceived to process large diameter logs has an adjustable pitch feeding and is driven by an electric motor 22 kW (TB 900) or 30 kW (TB 1200); the splitting power can be 40 (TB 900) or 50 (TB 1200) tons.
The feeding chain is strong thanks to its closed links and has a length of 1600 mm (5′ 2.99”), it could be longer on demand.
By means of this chain, the cut logs pass through the action of the splitting wedge. The dimensions of the output wood can be set electronically, from a minimal splitting measure is 20 x 20 mm (0.79 x 0.79”) for kindling.
TB 900 machine on average produces 18/20 bulk cubic meters (5,04/5,6 bulk cords) per hour of cut logs 250 mm (9.84”) height with splitting size 90 x 90 mm (3.54 x 3.54”).
