    • Disclosed is a smart ladder. The smart ladder may be A-frame type of ladders, such as A-frame ladders and A-frame platform ladders. The smart ladder includes right and left outrigger leg units which are swiveled coupled to the right and left sides of the ladder to provide side support. The ladder includes brace units facilitate in folding and unfolding of the ladder as well as the outrigger legs. An electronic system, which includes a sensor network, a processor and a warning system, is provided. The sensor network senses side inclination angle of the ladder and side force on the outriggers and predict potential hazards from exceeding load and angle thresholds. This enhances safe operation of the ladder and avoids injuries to the user and others in the vicinity.

    • A ground rod and guy stake extractor according to the present approach overcomes many deficiencies of contemporary methods, and allows for the rapid extraction of ground rods and guy stakes across a full range of environments, and at a wide range of extraction angles, with a straight pull on the item being extracted. Embodiments may be lightweight, easily transported, and operated by a single individual. Embodiments may include a winch, winch cable system, and support structure. The geometry is such that it is easy and straight forward to align the direction of pull with any rod or ground stake, and particularly for those driven into the ground within the commonly prescribed angular limits, thus assuring a continuous, steady pull of at least four feet in most embodiments. Guy stakes can therefore be easily extracted in one step, and typically ground rods (because of their length) in two steps.

    • In a tripod ladder (2), an erection and support mechanism (4) based on a vertically extending, triangular cross-section center post (34). This center post (34) is fastened at an upper end to the upper platform (10) of the ladder (2), defining a central axis (38) about which the ladder (2) vertically extends. This center post (34) acts as a vertical guide or tracking device at the vertex of the planes of extension of each of the major support legs (6, 8). A collar (46) slides along the center post (34) to coordinate the movement of the extending legs (6, 8). Braces (44) are pivotally affixed at one end to the collar (46) and at the other end to a leg (6, 8). Collar movement along the center post (34) thus controls the opening of the ladder (2). The triangular center post (34) defines angles of extension. Alignment channels (42) on the triangular collar (46) maintain each of the leg braces (44) in a substantially equal angular relationship.
    • 在三脚架梯(2)中,基于垂直延伸的三角形横截面中心柱(34)的安装和支撑机构(4)。 该中心柱(34)在上端紧固到梯子(2)的上平台(10),限定了梯子(2)垂直延伸的中心轴线(38)。 该中心柱(34)用作每个主要支撑腿(6,8)的延伸平面的顶点处的垂直引导或跟踪装置。 轴环(46)沿着中心柱(34)滑动以协调延伸腿(6,8)的移动。 支架(44)在一端枢转地固定到轴环(46)上,另一端枢转地固定到支腿(6,8)上。 沿着中心柱(34)的轴环运动因此控制梯子(2)的打开。 三角形中心柱(34)限定了延伸角度。 三角形环(46)上的对准通道(42)将每个支腿支架(44)保持为基本相等的角度关系。
