  • Patent number: 7108449
    Abstract: Methods and apparatus for power finishing freshly placed concrete in which the acoustic impedance of the treating equipment is made substantially equal to the acoustic impedance of the concrete slab being treated. Preferably, a powered, twin rotor riding trowel is provided with a pair of circular finishing pans that are attached to the conventional rotor blades used later in the finishing process. The pans are characterized by an acoustic impedance approximating the acoustic impedance of green concrete, thereby optimizing the energy transferred to the concrete. Preferred pans comprise ultra-high molecular weight polyethylene (UHMWPE) plastic. During troweling, the pans are frictionally revolved over the green concrete for finishing the surface without prematurely sealing the uppermost slab surface. Through the disclosed troweling method, a highly stable concrete surface results, and delamination is minimized. Alternative troweling uses pans coated with layered impedance matching material.

  • Patent number: 6962490
    Abstract: A concrete extruder attachment for a vehicle includes a hopper adapted to hold flowable concrete. The hopper has an upper concrete inlet and a lower concrete outlet. A slip form is connected to the lower concrete outlet. An internal vibrator causes concrete to flow from the hopper through the lower concrete outlet to the form. A mounting is provided which is adapted to mount to a vehicle. A hopper support is secured to the hopper. The hopper support is pivotally mounted to the mounting for pivotal movement between a first position with the hopper extending toward a first side of the vehicle and a second position with the hopper extending toward a second side of the vehicle. The support is selectively locked in one of the first position or the second position. The ability to pivot the hopper enables the concrete extruder to access corners.

  • Patent number: 6692185
    Abstract: An improved arrangement for adjusting crawler-type transport assemblies in a self-propelled construction vehicle between two differing “home” positions. The crawler transport assembly comprises a steering mechanism including a collar assembly operated via an actuator mounted to the frame of the apparatus for driving steering rotation of the transport assembly via the collar assembly. The collar assembly comprises a driving element integrally coupled to the actuator and a driven element integrally coupled to the transport assembly. The driven element can be affixed to the driving element selectively in two differing dispositions corresponding to the two “home” positions of the transport assembly.

  • Patent number: 6582152
    Abstract: The invention teaches a slip form paving machine which can be used for both zero clearance variable width and variable width conventional paving using the same paving pan. The main frame of the machine is designed to hydraulically extend and retract from varying desired widths. The paving assembly, attached to the main tractor assembly frame, is adjustable as wide as the width of the main frame of the machine or further past the exterior limits for additional clearance, if required. The paving pan, which is part of the pan assembly, can also be extended to conform to these various widths. In a “zero clearance” paving mode, the same pan is located behind the main tractor frame, whereas in conventional paving, the pan is located under the center of the main frame inside of the tracks. In addition, the paving pan can be adjusted to pave varying surface angles, if required.

  • Patent number: 6394410
    Abstract: An adjustable reinforcement insertion guide is installed within the slip form mold of a mobile concrete slip form machine, for guiding steel reinforcement screens into the mold interior during the casting of continuously poured concrete barrier walls (i.e. “Jersey Walls”). The guide is vertically adjustable, in order to clear curbs, open cut joints, etc, as required. Additional adjustment is provided for a series of laterally adjustable outlet panels on the back of the guide, which provide additional accuracy and adjustment in guiding the steel mesh or screen which passes through the guide. The guide is fixed to the mobile slip form machine (with the exception of the vertical adjustment of the guide relative to the slip form machine), and travels with the machine as fresh concrete is introduced into the slip form mold of the machine.
