A powered lift hand truck with a corresponding method of operation and control. The apparatus includes a powered lift hand truck configured to lift a load from a lowered to a raised position (and vice versa). The system uses the rotational speed to measure linear speed and enforce a consistent speed of the load. The system is programmed to lift/lower loads at the same speed, regardless of load overall weight. If, for example, the load is heavy, the system determines that the speed is below a predetermined threshold and increases the power so as to increase speed.

Powered lifting hand truck apparatus, system, and method

A hand truck for carrying and lifting a load comprising spaced vertical columns each having a channel. Rollers are captured in each of said channels that are capable of vertical movement along its respective channel. A first toe plate is affixed to said columns and adapted to extend horizontally during use. A second toe plate is attached to the rollers and adapted to move vertically along said columns between upper and lower positions. The first and second toe plates are in nesting relationship when the second toe plate is in its lower position.

Hand truck

In a preferred embodiment, an apparatus, comprising: a column () normally generally vertical when a device () of which the column () is a part is in an operating position; and a platform () operatively connected at one end to the column () and normally generally horizontal when the device () is in an operating position, the platform () being selectively raised or lowered to raise or lower a load placed on the platform ().

Lifting device and method

In a preferred embodiment, a mounting bracket for support of a window air conditioner on a window sill installed in a window opening in a wall of a building, the bracket including: a generally horizontal support member for supporting a portion of the window air conditioner extending outside of the building, a proximal end of the generally horizontal support member being for attachment to the window sill; a foot member to rest against an outside surface of the wall below the window opening; a strut member having an upper end thereof attached to an attachment point near a distal end of the generally horizontal support member and a lower end thereof attached to the foot member; and apparatus to selectively adjust height of the proximal end of the generally horizontal support member above the window sill, depending on construction of the window sill and obstacles in the window.
