The present invention provides a foldable demolition hammer trolley designed for floor removal operations. It comprises a first frame with a main rod, a moving assembly, and a pedal assembly. The moving assembly, located at the main rod's bottom end, includes a fixed axle and wheels. One side of a connecting part of the pedal assembly connects pivotally to the fixed axle and the other side is fixedly to a pedal pad. The second frame is pivotally attached to the first frame and includes a support frame part, a carrying frame part, a telescopic sleeve rod, an adjustment member, and first and second fixing assemblies. The support and carrying frame parts are pivotally connected. The telescopic sleeve rod and adjustment member between them allow distance adjustment. The fixing assemblies secure the demolition hammer's handle and body. This can reduce the force required by the operator.
