This ergonomic tool is designed to reduce physical efforts and prevent injuries thus improving health and safety of the workers in construction industry. An electric actuator is used to change the chisel attack angle while the handle height and position are fixed. This provides a comfortable working position for the operator in both removing tiles in lower chisel attack angles and removing mortar in higher chisel attack angles. It only weighs 65 lbs (or 29 kg) and when the handle is folded down its height is only 25in. It comes with three sizes of chisels; 1", 2" & 3". TB3 comes with a few additional features compared to its ancestors including a heavy duty angle adjusting system, a carriage handle, a push plate at the back, stronger structure and improved lubrication system.
