Abstract
A system for raising and lowering equipment and including a fixed support arm for attachment to an elevated support structure, a movable carriage for carrying the equipment, a cable extending between the fixed support arm and the movable carriage, and a winch for spooling and unspooling the cable to raise and lower the movable carriage relative to the fixed support arm. A locking mechanism secures the carriage in its raised position, and alignment guides position the carriage to make electrical connections as the carriage is engaged onto the support arm.
Claims28
A system for raising and lowering equipment, said system comprising a fixed support arm for attachment to an elevated support structure, a movable carriage for carrying the equipment, a cable extending between the fixed support arm and the movable carriage, and a winch for selectively spooling and unspooling the cable to raise and lower the movable carriage relative to the fixed support arm.
An elevated support mechanism comprising:
- an upper support member;
- a carriage movable between a raised position adjacent the upper support member, and a lowered position beneath the upper support member;
- a lifting system for raising and lowering the carriage;
- and
- a locking mechanism for securing the carriage in the raised position.
An elevated support mechanism comprising a carriage, a winch, a cable coupled to the carriage and the winch, and an overload/unspooling mechanism for deactivating the winch when an overload or underload is applied to the cable.
An elevated support mechanism comprising a carriage, a winch, a cable coupled to the carriage and the winch, and an end-of-spool shut-off mechanism for deactivating the winch when nearly all of the cable is unspooled from the winch.
An elevated support system for a surveillance camera, comprising:
- a support arm having a winch mounted thereto for raising and lowering the surveillance camera, a first upper pulley, an upper electrical contact, and an upper alignment guide member;
- a carriage for mounting the surveillance camera to, and comprising at least one lower pulley, a lower electrical contact for cooperative engagement and disengagement with the upper electrical contact of the support arm, and a lower alignment guide member for cooperative engagement and disengagement with the upper alignment guide member;
- a cable having a first end spooled onto the winch, extending over the first upper pulley, downward and around the at least one lower pulley, and back up to a second end affixed to the support arm.
