Abstract

Trench excavator, of the type having a support arm for the recirculating excavator chain, which can be lowered around a horizontal tilt axis on one side of the excavator frame and with a positioning device for the lowering of the carrying arm between a position of high rest and a working position corresponding to the support arm folded down, so that the folding axis simultaneously carries the chain drive wheel for the digging chain, a chain plate being provided for the chain drive wheel protection for the curved chain that covers said chain drive wheel in front of the excavator frame and that otherwise extends laterally beyond the chain wheel; characterized by the fact that the chain protection plate is configured as a hollow cover and consists of at least two parts that can be folded into each other and that are respectively attached to the support arm for the excavator chain and to the frame of the excavator. In such a way that, with the support arm raised in the rest position, they are folded over each other and with the support arm folded down in the working position, they are deployed to the point of almost completely covering the top and inside the drive wheel for excavator chain chain.
