摘要： A cement screeding system in the form of a powered roller screed with a wet screed attachment. The wet screed attachment includes a wet screed shoe. A handle is rotationally isolated from the screed roller and is rigidly coupled to this wet screed shoe. As such, motion of this handle is transmitted to the wet screed shoe in a replicating fashion.

摘要： A curb former (10) includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).
