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.
Claims21
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.
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;
- an adjustable width mold including a left sideform assembly, a center portion and a right sideform assembly;
- and
- a first suspension assembly including:
- a first carriage movably mounted on the machine frame such that the first carriage is laterally movable relative to the machine frame, the first carriage being connected to one of the left and right sideform assemblies;
- and
- a first suspension actuator configured to move the first carriage and the one of the left and right sideform assemblies relative to the machine frame.
A method of adjusting a width of a mold of a slipform paver, the slipform paver including an adjustable width machine frame supported on a plurality of ground engaging units, method comprising:
