  • Patent number: 9757601
    Abstract: 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.

  • Patent number: 9677335
    Abstract: A firefighting or rescue apparatus includes an aerial ladder and at least one of a rung alignment status indicator and a load status indicator. The rung alignment status indicator can include a lighting strip having multiple lighting elements on the ladder that are selectively illuminated depending on whether first rungs of one section of the ladder and second rungs of another section of the ladder are aligned or misaligned. The load status indicator can include a lighting strip including multiple lighting elements on the ladder and/or at a control console that are selectively illuminated depending on whether the ladder is overloaded beyond an aerial ladder capacity rating or other value. A user on the aerial ladder and/or at a control console can view the indicators to evaluate rung alignment and load status.

The rung alignment status indicator can include a lighting strip having multiple lighting elements on the ladder that are selectively illuminated depending on whether first rungs of one section of the ladder and second rungs of another section of the ladder are aligned or misaligned. A user on the aerial ladder can view the rung alignment status indicator and discern whether the ladder has appropriate rung alignment so the user can attain a safe foothold when climbing it. The load status indicator can include a lighting strip including multiple lighting elements on the ladder and/or at a control console that are selectively illuminated depending on whether the ladder is overloaded beyond an aerial ladder capacity rating or other value.
