Abstract
A mobile anchor cart assembly includes a cart including a frame defining a front side and a rear side, the front side disposed opposite from the rear side, the frame defining a front foot and a rear foot, the front foot and the rear foot configured to rest upon a ground surface when the cart is in an anchored position, the front foot and the rear foot configured to clear the ground surface when the cart is in a mobile position; at least one tie-off point attached to the frame; at least one handle extending outward from the rear side of the frame, the at least one handle configured to selectively position the cart about and between the anchored position and the mobile position; and an axle assembly mounted on the front side; and a load defining a load center of gravity.
Claims20
A mobile anchor cart assembly comprising:
- a cart comprising:
- a frame defining a front side and a rear side, the front side disposed opposite from the rear side, the frame defining a front foot and a rear foot, the front foot and the rear foot configured to rest upon a ground surface when the cart is in an anchored position, the front foot and the rear foot configured to clear the ground surface when the cart is in a mobile position;
- at least one tie-off point attached to the frame;
- at least one handle extending outward from the rear side of the frame, the at least one handle configured to selectively position the cart about and between the anchored position and the mobile position;
- and
- an axle assembly mounted on the front side;
- and
- a load defining a load center of gravity, the load center of gravity being vertically aligned with the axle assembly when the cart is in the anchored position.
A cart comprising:
- a frame defining a front side and a rear side, the front side disposed opposite from the rear side, the frame defining a front foot and a rear foot, the front foot and the rear foot configured to rest upon a ground surface when the cart is in an anchored position, the front foot and the rear foot configured to clear the ground surface when the cart is in a mobile position, the frame comprising a weight rack attached to the front side, the weight rack comprising a weight bar configured to support a load;
- at least one tie-off point attached to the frame;
- at least one handle extending outward from the rear side of the frame, the at least one handle configured to selectively position the cart about and between the anchored position and the mobile position;
- and
- an axle assembly mounted on the front side, the weight bar configured to position a load center of gravity of the load vertically aligned with the axle assembly when the load is supported on the weight bar and the cart is positioned in the anchored position.
A method for using a mobile anchor cart assembly, the method comprising:
- moving the mobile anchor cart assembly to a worksite in a mobile position, the mobile anchor cart assembly comprising a cart and a load, the load defining a load center of gravity, the cart rolling on at least one wheel of an axle assembly of the cart in the mobile position along a ground surface of the worksite, the cart comprising a frame and a first tie-off point attached to a first side of the frame, the frame comprising a front foot and a rear foot, the front foot and the rear foot clearing the ground surface in the mobile position, a first direction extending perpendicularly outward from the first side of the frame, a first directional work zone corresponding to the first direction;
- directing the first directional work zone toward a fall hazard of the worksite;
- repositioning the mobile anchor cart assembly from the mobile position to an anchored position, the front foot and the rear foot resting on the ground surface of the worksite in the anchored position, the at least one wheel raised above the ground surface in the anchored position, the load center of gravity being vertically aligned with the axle assembly when the cart is in the anchored position;
- and
- attaching a fall protection system of a first worker to the first tie-off point.
