Abstract
A chain bar unit for a wall saw is presented herein. The chain bar unit can include a bar configured to receive a circulating chain or wire around a perimeter of the bar. The chain bar unit also can include a driving gear for driving the chain or wire around the bar, the driving gear configured to be coupled to an output shaft of the wall saw. The chain bar unit further includes the bar being tapered from an end proximate to the driving gear to a distal end having a distal end radius, wherein a width of the bar at the proximate end, is at least two times the distal end radius of the distal end.

A chain bar unit for a wall saw, comprising
- a bar configured to receive a circulating chain or wire around a perimeter of the bar;
- a driving gear for driving the chain or wire around the bar, the driving gear configured to be coupled to an output shaft of the wall saw;
- and
- a safety cover operably coupled to the bar to partially expose the bar responsive to pivoting of a saw arm of the wall saw;
- the bar being tapered from an end proximate to the driving gear to a distal end having a distal end radius, wherein a width of the bar at the proximate end, is at least two times the distal end radius of the distal end.
