An old favourite the Multi-Bar cropper as its name suggests is used for precast piles (PCC ) with four or more reinforcement bars (rebar).
At only 450kgs the cropper can be mounted to a minimum 6T Excavator.
The cropper is designed to remove sections of concrete at approx 250mm per crop, the 4 powerful rams and blades missing the rebar and penetrating into the centre of the pile to leave a minimum of trimming.
Not recommended for pile caps or tight sites – requires a 600 bucket dig all around pile edge.
Lower the cropper over the pile and reduce at 250mm intervals, broken pile sections to be removed. Ensure the last bite at finish level is of at least 250mm to ensure a good cut is obtained. Tugging on the cropper could result in a blade failure so is not recommended.
