Abstract
A portable rotary trailer tipper is provided for emptying the trailer contents through opening the open top of the trailer. The tipper includes an elongated transport that is portable and supports a trailer inverter. A platform for supporting the trailer is positioned along one side of the transport. A dumping chute for receiving the material dumped from the trailer is positioned along the opposite side of the transport. A trailer positioned upon the platform is engaged by the inverter then rotated upwardly and across the transport to dump material from the trailer into the chute. The chute directs the dumped material into a landfill site. A method of emptying material successively from a stream of trailers is also provided.
Claims15
A portable tipper for dumping material from a trailer having an open top portion, comprising:
- a portable elongate transport having a longitudinal axis and opposing first and second sides;
- a trailer inverter having a tipper device mounted to the transport, and a carriage supported by the tipper device, the carriage having an extendable and retractable support portion;
- and
- the carriage having a rest configuration wherein the support portion is retracted to permit the trailer to be moved into tipping position closely alongside the carriage without the carriage substantially vertically supporting the trailer, and the carriage having an extended tipping configuration wherein the support portion is extended from the carriage to engage and vertically support the trailer in the tipping position, the tipper device inverting the carriage about at least one axis which is substantially parallel to the longitudinal axis to dump material from the open top portion of the trailer beyond the second side of the transport.
A system for emptying a trailer containing dumpable material at a dumping site, the trailer having an open top, comprising:
- a portable elongate transport, the transport having a longitudinal axis;
- an inverter, the inverter having a tipper device mounted upon the transport, the tipper device rotatably supporting an elongate tipping carriage, the tipping carriage having a vertical support surface and an extendable and retractable horizontal support member, the tipping carriage extending parallel with the longitudinal axis;
- and
- the tipping carriage having a retracted rest configuration wherein the horizontal support member is retracted to permit the trailer to be positioned in an upright orientation alongside the vertical support surface without being substantially supported by the carriage, and the carriage having an tipping configuration with the horizontal support member extended to vertically support the trailer while the trailer is in the upright orientation alongside the vertical support surface, and the horizontal support member and the vertical support surface vertically and horizontally supporting the trailer while the tipping device rotates the carriage with the trailer held therein.
A tipper for dumping material from a trailer, comprising:
- a portable transport;
- a tipper device mounted on the transport and supporting a tipping carriage, the tipper device having a tipper frame member mounted upon the transport;
- a T-shaped member pivotally mounted on the tipper frame member, the T-shaped member having a crossarm and a stem with an intermediate portion thereof pivotally attached to the tipper frame member, the T-shaped portion crossarm having an upper end pivotally connected to the tipping carriage;
- a primary actuator interconnecting a lower end of the T-shaped member crossarm and the transport, the primary actuator being pivotally connected to the crossarm lower end and to the transport;
- and
- a secondary actuator interconnecting the base of the T-shaped member stem and the tipping carriage, the secondary actuator extending alongside the stem, the secondary actuator being pivotally connected to the stem base and to the tipping carriage.
