Abstract

A side recovery system is disclosed that includes a base configured to be supported on a vehicle and a boom supported by the base and having a first end and a second end. The boom is rotatable relative to the base about a substantially horizontal axis between a first position and second position. The second end of the boom being positioned at a first side of the vehicle in the first position and at an opposite second side of the vehicle in the second position. The system also includes a first sheave supported at the second end of the boom and configured to receive a load bearing cable. The cable configured to remain received by the first sheave as the boom rotates between the first position and the second position.

Claims20

Dependent claims

A side recovery system for a recovery vehicle having a longitudinal axis extending in a fore and aft direction of the vehicle, the system comprising:

a base configured to be supported on the vehicle;
a boom supported by the base and having a first end and a second end, the boom being rotatable relative to the base about a first axis configured to be substantially parallel to the longitudinal axis of the vehicle between a first position and a second position, the second end of the boom being positioned at a first side of the vehicle in the first position and at an opposite second side of the vehicle in the second position;
a first sheave supported at the second end of the boom and configured to receive a load bearing cable, the cable configured to remain received by the first sheave as the boom rotates between the first position and the second position;
a winch supported at the base, the winch having a drum configured to receive the cable;
and
a cable guidance system for directing the cable from the winch to the first sheave, the cable guidance system comprising:
a second sheave coupled to the base and associated with directing the cable when the boom is in the first position;
a third sheave coupled to the base and associated with directing the cable when the boom is in the second position;
and
a winding system having a lead sheave and a support member for supporting the lead sheave, the lead sheave being configured to direct the cable from the winch to at least one of the second sheave and the third sheave, the support member being rotatable about an axis.

7 more elements

A recovery vehicle comprising:

a chassis;
a side recovery system supported at the chassis and including a boom that is selectively positionable between a first side of the vehicle and an opposite second side of the vehicle;
and
fleet angle management system configured to supply a cable to the side recovery system, the fleet angle management system comprising:
a winch having a drum configured to receive the cable and rotatable about a first axis;
an output sheave configured to receive the cable from the winch;
and
a winding device for guiding the cable from the winch to the output sheave, the winding device including a lead sheave and a support member for supporting the lead sheave, the lead sheave being rotatable about a second axis that is substantially parallel to the first axis, the lead sheave having an input side configured to receive the cable from the winch and an output side configured to direct the cable the output sheave, the support member being rotatable about a third axis that is substantially perpendicular to the first axis and the second axis,
wherein a force imposed by the cable on the input side of the lead sheave causes the support member to rotate about the third axis as the cable winds on and off the drum thereby reducing the fleet angle of the cable,
wherein the input side of the lead sheave follows the cable in a sweeping arc as the cable winds on and off the drum.
