Firefighting or rescue apparatus including a ladder mounted recovery winch
A firefighting or rescue apparatus includes a ladder to which a recovery winch is operably mounted so that the winch can be used to move, upright, lift or otherwise manipulate target objects at an emergency location. The ladder can include a pulley detachably mounted to the ladder distal from the winch, the pulley adapted to suspend a cable extending from the winch at an upper end. In operation, the winch moves along with the ladder as the ladder moves, so that the winch and pulley can be strategically located over a target object for movement thereof. The apparatus can include a remote control connected to the winch for operation of the winch by a user.
1. An aerial firefighting apparatus, comprising:
a frame configured to enable transportation of the apparatus to an emergency location, the frame including a forward portion, a rearward portion, a first side and a second side opposite the first side;
a ladder that is both extendible and retractable, the ladder comprising a base boom, and a fly boom retractably and extendably joined with the base boom, and at least one upper ladder section movably joined with the base boom so that the upper ladder section can be extended and retracted relative to the base boom to provide extension and retraction of the ladder, the ladder being movably mounted relative to the frame so that the ladder can be raised from a generally horizontal stored position to a raised position wherein the ladder extends upwardly at an angle from the frame;
a turntable to which the ladder is mounted, the turntable being configured to selectively rotate so that the base boom can be swung to a plurality of positions;
a winch mounted to and adjacent the base boom distal from the turntable so that the winch moves along with the base boom when the base boom moves, the winch including a spooled supply of cable having an attachment element located at an end of the cable;
a pulley mounted adjacent a distal end of the fly boom and spaced a distance from an upper end of the ladder so that the pulley is moveable toward and away from the base boom, on the fly boom, and so that when the ladder is in the raised position the pulley is above the winch;
a remote control being remote from the winch but operably connected to the winch for operation of the winch,
a stabilizer leg configured to stabilize the aerial firefighting apparatus,
wherein the remote control is configurable in a locked mode and an unlocked mode, wherein the locked mode is automatically attained when at least one of: the ladder is at an angle greater than a predetermined angle, the ladder is rotated at an angle relative to a longitudinal axis of the frame greater than a predetermined rotation angle, the stabilizer leg is not sufficiently deployed, and the fly boom is extended greater than a predetermined amount,
wherein the attachment element is adapted to join the cable with a target object located adjacent the frame,
wherein the remote control is operable by a user remotely from the winch to uptake the cable relative to the winch and thereby configured to exert a force on the target object to which the attachment element is attached, whereby the target object can be at least one of lifted and moved with the winch mounted on the underside of the base boom.
2. The aerial firefighting apparatus of claim 1 wherein the remote control is coupled to at least one of the frame and the winch with a cord of a length that enables the user to operate the remote control while in plain view of the target object.
3. The aerial firefighting apparatus of claim 2 wherein the cable does not extend beyond the upper end of the ladder.
4. The aerial firefighting apparatus of claim 1 ,
wherein the pulley is mounted to the fly boom below the upper end of the ladder,
wherein the winch is below the pulley and below the distal end of the fly boom when the ladder is in the raised position.
5. The aerial firefighting apparatus of claim 1 comprising a cab and a ladder support, the ladder support extending upwardly from the frame and adapted to support the ladder when the ladder is in the generally horizontal stored mode, wherein the winch is mounted to the base boom in a location so that when the ladder is in the generally horizontal stored mode, the winch is rearward of the cab.
6. The aerial firefighting apparatus of claim 1 comprising a tank adapted to store firefighting fluid and a pump adapted to pressurize the firefighting fluid and transport it to a waterway joined with the ladder.
7. An aerial firefighting apparatus, comprising:
a mobile frame including a forward portion, a rearward portion, a rear axle located in the rearward portion, a first side and a second side opposite the first side;
a ladder movably mounted relative to the frame so that the ladder can be raised from a generally horizontal stored position to a raised position wherein the ladder extends upwardly at an angle from the frame, the ladder comprising a base boom and a fly boom retractably and extendably joined with the base boom;
a turntable to which the ladder is mounted, the turntable being mounted rearward of the rear axle, the turntable being configured to selectively rotate so that the ladder can be swung to a plurality of positions;
a winch mounted adjacent the base boom distal from the turntable so that the winch moves along with the base boom when the base boom moves, the winch including a spooled supply of cable having an attachment element located at an end of the cable;
a pulley detachably mounted adjacent a distal end of the fly boom and spaced a distance from an upper end of the ladder, the pulley being moveable toward and away from the base boom, the pulley being distal from the winch so that when the ladder is in the raised position the pulley is above the winch; and
a control connected to the winch for operation of the winch,
a stabilizer leg configured to stabilize the aerial firefighting apparatus,
wherein the control is configurable in a locked mode and an unlocked mode, wherein the locked mode is automatically attained when at least one of: the ladder is at an angle greater than a predetermined angle, the ladder is rotated at an angle relative to a longitudinal axis of the frame greater than a predetermined rotation angle, the stabilizer leg is not sufficiently deployed, and the fly boom is extended greater than a predetermined amount,
wherein the attachment element is adapted to join the cable with a target object located adjacent the frame, but separate from the apparatus;
wherein the control is operable by a user to move the cable and thereby configured to exert a force on the target object to which the attachment element is attached, whereby the target object can be at least one of lifted and moved with the winch.
8. The aerial firefighting apparatus of claim 7 wherein the control is remotely located from the winch, wherein the control includes a cord coupled to at least one of the frame and the winch and of a length that enables the user to operate the control while in plain view of the target object.
9. The aerial firefighting apparatus of claim 7 comprising a mounting plate joined with the ladder, wherein the winch is mounted to the mounting plate.
10. The aerial firefighting apparatus of claim 9 comprising a cab, wherein the mounting plate is mounted to the boom in a location so that when the ladder is in the generally horizontal stored mode, the winch is rearward of the cab.
