An anti-lift/anti-twist hinge which includes a bracket having a wall and a pair of spaced converging flanges. The flanges have aligned openings therein for accommodating a hinge pin. The hinge bracket is attached to a gate and prevents the upward rooted or rubbed shifting of the gate and bracket by the interfering fit between the pin and bracket. When tightened against the gate the bracket flattens a side wall of the supporting gate tube to prevent twisting of the bracket relative to the tube.
A transportable elevating security tower, having: a selectively closable base housing, an observation enclosure, an electrically powered hydraulic lift apparatus, and electronic control device, adapted to activate said hydraulic lift system.
A movable antiballistic bench, the bench comprising: a base, the base comprising a bullet resistant material; a plurality of support legs extending away from a first surface of the base, the support legs comprising a bullet resistant material and having distal ends which are adapted to contact a support surface; a seatback, the setback attached to the base at an angle other than 90, the seatback comprising a bullet resistant material.
A stackable, portable, vehicle traffic barricade having a molded elongated body with a generally extruded triangular shape having a longitudinal axis; a base; a top; a first pair of opposing sides disposed between the top and the base; a second pair of arcuate opposing sides disposed between the top and the base; a plurality of vertically disposed fillable cavities disposed through the top of the body; and a plurality of caps, where each of the caps has a cross sectional shape suitable for functionally engaging a corresponding cavity.
A tow trailer for use with a motor vehicle, the tow trailer having: a frame, the frame having a hitch; a fork assembly, the fork assembly rotatably attached to the frame; a pair of forks, the forks slidingly attached to the fork assembly; a hydraulic actuator, the hydraulic actuator, the actuator having a first hydraulic cylinder attached to the fork assembly at a point suitable to cause rotation of the fork assembly relative to the frame, the actuator further having a second hydraulic cylinder, the second hydraulic cylinder attached to the forks to selectively move the forks along a vertical axis independently of the fork assembly rotation.
Concrete Traffic Control Barrier With Thermoplastic Cover
A modular traffic barricade comprising: a concrete substrate disposed within a molded thermoplastic outer layer and comprising an interior surface, an exterior surface, a selectively closable access point, and a predetermined molded to the exterior surface of the outer layer.
