Primary Log Breakdown
Sawquip has developed this efficient 8’-16’ log infeed to replace existing infeeds that are space restrained and require accurate positioning to chipping canters and/or saws.
The first two modules of the infeed have vertical bar rolls to permit final log turning as the log exits the log turner.
Subsequent roll assemblies have two mounted driven vertical spike rolls with each roll positioned against a log to transport it forward and ensure also that it remains in contact with the central anvil upon entering the chipping heads and/or saws.
The modular concept permits various log forms and diameters to be accommodated.
Individual rolls are driven by electric motor-reducers with pulleys and power belts. Drives are mounted over the rolls.
The vertical press rolls are supported on pilot bearings at each end and are mounted on top and bottom steel fabricated pivoting assemblies. Each roll assembly is activated against a log by a hydraulic cylinder with controls.
Each module with two vertical roll assemblies is able to maintain centering contact on a log by means of an inter-linkage between the rolls activated by a pneumatic cylinder assembly.
The chromed steel central anvil supports a log as it moves forward and has a grooved, removable section between the last two vertical roll modules to assist in centering a log to the central anvil of a chipping canter and/or saws.
Maintenance and repairs of the various components are facilitated by easy access to all components of the vertical rolls, linkage and cylinder assemblies.
