Abstract
A heavy duty rotary concrete mixing drum (16) for coupling to a vehicle (10) having a powered drivetrain (18) for rotating the drum comprises a wall and at least one projection (32). The wall (33) includes an inner surface (34) defining a volume and an outer surface (36). The at least one projection is coupled to the wall and extends from the inner surface of the wall. The projection includes a body and a support member (48) disposed within the body.
Claims35
A concrete mixing truck for transporting concrete from one location to another comprising:
- a chassis including:
- a frame, a first power source coupled to the frame, wheels coupled to the frame, and a first drivetrain coupling the first power source and the wheels;
- a mixing drum coupled to the frame and to a second drivetrain, the drum comprising:
- a wall including an inner surface defining a volume and an outer surface;
- and
- at least one formation coupled to the wall and extending from the inner surface of the wall, the formation including a body, a support member and at least one spacer disposed proximate the support member, the body including a base region, an intermediate region and an end region, the support member and the at least one spacer being embedded within the end region, the at least one spacer being a helical spring that resiliently engages and substantially surrounds the support member, the helical spring extending from the support member to an exterior of the body.
A concrete mixing truck for transporting concrete from one location to another comprising:
- a mixing drum comprising:
- a wall including an inner surface defining a volume and an outer surface;
- and
- at least one formation coupled to the wall and extending from the inner surface of the wall, the formation including a body, a support member and at least one helical spring that at least partially extends around a periphery of the support member, the support member and the at least one helical spring being embedded within the end region.
