Abstract: The top surface of an insert abuts with a form, with a tube extending into an aperture and sliding on a form post in the form. A rod inserted through the form, form post and tube holds the insert in place while castable material is poured in. The form is inverted with the guard rail base inside, the rod can be slid out of the form, and the form is removed. The handle is gripped by a claw on the obtuse angled chassis of a transporter. A handle on the chassis can be pushed to raise the guard rail base and to move the guard rail base on the surface by wheels. The guard rail base can be placed upon a pad having notches in its border.

Wheels are rotatably mounted to the first ends of the frame sides (12). An I-shaped main frame (40) is pivotably mounted to the frame about a first frame axis (J) generally perpendicular to the pan axis (A) and also a second frame axis (E) generally parallel to the pan axis (A). By pivoting the main frame (40) about the first frame axis (J), a steering function is provided to the frame. By pivoting the main frame (40) about the second frame axis (E), the frame is pivoted between an actuated position with the weight pan (18) resting upon a surface and a transport position with the weight pan (18) spaced from the surface and with the frame moveable on the surface (102).

Abstract: A gate system (10) includes two spaced sides (12, 14) defining a work area (16) between the sides (12, 14). A first opening (18) is defined between first ends of the sides (12, 14), and a second opening (38) opposite to the first opening (18) is defined between second ends of the sides (12, 14). Two gates (82, 92) for opening/closing the first and second openings (18, 38) are respectively coupled with two shafts (40, 50) rotatably supported by one of the sides (12, 14). The shafts (40, 50) are rotatably interconnected wherein pivoting of one of the gates (82, 92) in a direction causes pivoting of the other gate (82, 92) in an opposite direction. Each gate (82, 92) includes a groove (85, 95) that receives a vertical beam (60, 62) of the other side (14) when the gate (82, 92) is in a closed position. Biasing elements in the form of gas cylinders (110, 120) between the side (12) and the gates (82, 92) prevent the gates (82, 92) from slamming into their closed positions.

Abstract: A gate (106) includes a panel (112) movable relative to a fixed member (110) between an open position and a closed position. A linkage (140) is pivotally mounted to the panel (112) about a latch pivot axis. A catch (130) is pivotally mounted to the linkage (140) about a catch pivot axis spaced from and parallel to the latch pivot axis. The catch (130) is movable between a latched position engaged with the fixed member (110) and an unlatched position disengaged from the fixed member (110). The catch (130) defines a groove for slideable receipt on the fixed member (110). When the catch (130) is in the latched position and the panel (112) is in the closed position, the catch (130) abuts against opposite sides of the fixed member (110) along an extended length such that forces are applied on each side at spaced locations to resist twisting forces.

Abstract: Cantilever gates (10) in the form of parallelograms include first and second bars (40) and a toe board (140) extending between and pivotally mounted to first and second posts (20, 30) and moveable between closed and open positions. Gas struts (46) assist in moving the gate (10). A lock (60) in the form of a pivotal latch (62) holds the gate (10) in its open position. A slide receptor (80) slideably receives the second post (30) as the gate (10) moves from the open to the closed position and can be removably secured to a support surface mounting plate (82). A pair of cantilever gates (10) can have their respective second posts (30) slideably related.

Abstract: A protector (10) includes first and second frames (30a and 30b) spaced from each other and mounted at two opposite sides of a structure (80). Bach of the first and second frames (30a and 30b) includes two columns (34) and a cross bar (32) interconnected between the columns (34). Each column (34) includes a base (12a, 12b, 12c, 12d) mounted to a bottom thereof. Connecting rods (40) are mounted between the first and second frames (30a and 30b) and each include first and second ends (41) removably interconnected to the cross bars (32). The connecting rods (40) are spaced from each other and located above and extend across the structure (80). A brace (50) includes a first end (52) pivotably mounted to one of the columns (34) and a second, end engaged with the structure (80). The level of the connecting rods (40) is adjustable to suit the height of the structure. Weights (18) may be mounted to the bases (12a-12d) to increase the resistance of the protector (10) to wind lift.

Abstract: A cart (10) facilitates collection, storage and distribution of folding warning lines (200). The cart (10) includes a framework (12) with a rolling support (100) to allow mobility and a stabilizer (120) to engage a work surface. The framework (12) has a handlebar (110), which enables the framework (12) to be tilted rotationally about the rolling support (100) and pushed. The framework (12) has a storage area (18) located between first and second sides (14, 16) and for receiving rigid members (201) of the folding warning lines (200). A plurality of notches (70) defined in a top member (32) and a plurality of slots (72) defined in a bottom member (48) of the framework (12) are adapted to receive and constrain the rigid members (201) in the storage area (18). The framework (12) has a holder (78) adapted to hold a flaccid member (202) of the folding warning lines (200).

Abstract: A saw (10) facilitates cutting of roofing and includes a frame (12) that is mobile on a work surface. A locking mechanism (40) locks the frame (12) into a transport position. Actuating a release lever (60) allows the frame (12) to be adjusted into a working position. A shaft (14) rotatably mounted by first, second and third bearings (74, 75, 76) has saw blades (16, 18) and a pulley (77) for connection with a drive belt (80). The drive belt (80) passes through a hole (79) in the frame (12) to connect to a drive (81) to rotate the shaft (14) and the saw blades (16, 18). The third bearing (76) is mounted to a bearing support (85). The frame (12) has a gap (84) communicating the hole (79) with an exterior edge (78) of the frame (12) proximate the third bearing (76), with the bearing support (85) removably and replaceably mounted to the frame (12) and spanning the gap (84).
