Embodiment Construction

[0032] figure 1 A self-propelled ride-on concrete finishing screed 20 is shown equipped with a transport system 22 constructed in accordance with a preferred embodiment of the present invention positioned almost entirely under a cage or enclosure 24 of the screed 20 . Although shown with a commonly understood ride-on or straddle screed, it should be understood that the invention is applicable to any powered concrete finish level that cannot be easily manually moved by the operator without considerable effort. machine. That is, it is conceivable that a riding power screed or even a walking screed having a configuration other than that shown could also be equipped with a transport system according to the invention.

[0033] refer to Figure 1-3 and in particular figure 1 Initially, the concrete finisher 20 according to the preferred embodiment of the present invention includes as its main body a rigid metal frame 26, an upper deck 28 mounted on the frame 26, an operator's pla...

Abstract

A self-propelled concrete finishing trowel has an integrated transport system that allows the towel to be moved from location to location. The transport system includes a pair of spaced wheel assemblies, each including a pair of wheels that are connected to a frame of the trowel. The wheels of each respective wheel assembly are connected to one another via a powered actuator such as a double acting hydraulic cylinder. The powered actuator is actuatable to raise and lower the first and second wheels from a stowed position in which the wheels are located above the ground and the blades are supported on the ground to a deployed position in which the wheel are supported on the ground and the blades are raised from the ground.

Description

technical field [0001] The present invention relates generally to concrete finish screeds, and more particularly to a transport system for a powered finish screed. The invention also relates to a concrete finishing screed, such as a ride-on screed, having an integrated transport system that enables the screed to be wheeled within and from the job site to and from the job site. . Background technique [0002] A variety of machines exist for leveling or otherwise finishing wet concrete. These machines range from simple hand-held trowels to walking screeds and self-propelled ride-on screeds. Regardless of the mode of operation of these screeds, power screeds typically include one to three rotor assemblies that rotate relative to the concrete surface. [0003] Ride-on concrete finishers finish large areas of concrete faster and more efficiently than manually propelled or guided hand-held or walk-behind finishers. Ride-on concrete finisher screeds typically include a housing ...
