Abstract
An adjustable width mold apparatus for a slipform paver includes a center portion and left and right sideform assemblies. The left and right sideform assemblies are movably mounted on a machine frame. Left and right actuators can independently move the left and right sideform assemblies relative to the machine frame. A mold width of the mold is adjustable without adjusting a width of the machine frame. The mold can be laterally shifted in position relative to the machine frame.
Claims15
An inset slipform paver, comprising:
- a machine frame;
- at least one left ground-engaging unit and at least one right ground engaging unit configured to support the machine frame from a ground surface along left and right support paths such that a forward operating direction of the machine frame is defined and such that the machine frame has a frame width transverse to the forward operating direction;
- and
- an adjustable width mold suspended from the machine frame between the left and right support paths such that a mold width of the adjustable width mold is adjustable without adjusting the frame width of the machine frame, the adjustable width mold including:
- a center portion;
- a left sideform assembly;
- a right sideform assembly;
- one or more left spacers configured to be received between the left sideform assembly and the center portion;
- and
- one or more right spacers configured to be received between the right sideform assembly and the center portion.

- a left suspension assembly suspending the left sideform assembly from the machine frame such that the left sideform assembly is movable relative to the machine frame;
- and
- a right suspension assembly suspending the right sideform assembly from the machine frame such that the right sideform assembly is movable relative to the machine frame;
- wherein the left suspension assembly includes:
- a left suspension frame fixedly attached to the machine frame and including a guide;
- a left carriage movably engaged with the guide so that the left carriage is movable relative to the left suspension frame along the guide, the left carriage being connected to the left sideform assembly;
- and
- a left suspension actuator configured to move the left carriage and the left sideform assembly relative to the machine frame.
