A bollard wall gate system including a lockable access door enclosing the gate which is easy-to-operate and resistant to tampering. The bollard wall gate system generally includes one or more bollard panels which form a continuous bollard wall. Each of the bollard panels includes a passageway which may be selectively opened or closed by use of a gate. The gate includes a plurality of gate members which may be raised to open the gate or lowered to close the gate. The bollard panels include an enclosure through which the gate extends. A locking device may be utilized to selectively lock the gate in its opened or closed position, with the locking device being connected to the gate within the enclosure so as to prevent tampering or unauthorized access.

A vertically folding barrier gate arm has a proximal first segment and a distal second segment connected by a pivot hinge allowing them to fold. An extension set pivotally affixed to an outer offset bracket on the housing for the motor of the gate arm is connected to an outer offset bracket on the distal gate arm segment by a multi-articulated compound hinge formed by a plurality of links attached to each other by hinges providing a constrained range of rotation relative to each other. The gate arm translates from a fully extended position where the proximal and distal gate arm segments are parallel and co-linear along a horizontal longitudinal axis, to a vertically folded position where the proximal and distal gate arm segments lie substantially against each other within the plane of rotation of the first segment.

A mezzanine gate assembly is adapted to provide ingress and egress to an elevated platform while safely preventing falls and injury to workers positioned thereon or even below the mezzanine platform. The mezzanine assembly generally includes a support assembly which has a first and second upright support members. Each of the first and second upright support members has a base portion fixedly attached to the elevated platform and an upper portion which is configured to function as a post adjacent to the respective terminating railing. The mezzanine gate assembly comprises an interior gate assembly and an exterior gate assembly. Generally, each of the interior and exterior gate assemblies are designed to move and pivot through a path of motion which provides a plurality of points of travel. The interior gate assembly is operably designed to engage with and deviate rearward while the load is delivered to the platform via forklift in order to provide a barrier between the respective railing and side of the load. The exterior gate assembly is operably designed to provide a barrier while the load of goods is manually removed from the pallet.

A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.

An access control device (1) for blocking or opening a passage (2) for persons or vehicles. The access control device comprises one or two blocking bodies (3, 3), each arranged on a carrier (4, 4). Each blocking body (3, 3) comprises a mechanically reversibly deformable element (5, 5) which, in a first position, is substantially planar and opens the passage (2) and, in a second position, assumes a curved shape which blocks the passage (2). One or both ends of the deformable element (5, 5) are connected to an actuator (7). A controller controls the deformable element for transferring them first between the first and second positions. When transferring the deformable element from the first to the second position, either the distance between the ends of the respective blocking body is reduced or, when the ends have a constant distance, the length of the blocking body is increased.

A bollard wall gate system including a lockable access door enclosing the gate which is easy-to-operate and resistant to tampering. The bollard wall gate system generally includes one or more bollard panels which form a continuous bollard wall. Each of the bollard panels includes a passageway which may be selectively opened or closed by use of a gate. The gate includes a plurality of gate members which may be raised to open the gate or lowered to close the gate. The bollard panels include an enclosure through which the gate extends. A locking device may be utilized to selectively lock the gate in its opened or closed position, with the locking device being connected to the gate within the enclosure so as to prevent tampering or unauthorized access.

A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.

There is provided a barrier and a method of opening and closing a barrier. The barrier including a first arm moveable about a first support, a second arm moveable about a second support and at least one coupling. The first and second supports are spaced across an opening and the barrier is arranged between an open and closed position, such that in the closed position, the arms are arranged in combination to traverse the opening. The barrier is further arranged in a locked position, such that the coupling is slidably coupled to the first and second arms. The barrier improves the safety of loading bay areas in order to allow the efficient transfer of goods on freight transportation vehicles.

A safety barrier assembly for a parking garage is positioned in proximity to an opening in a floor of the parking garage that accommodates vertical movement of a VRC between floors of the parking garage. The safety barrier assembly has left and right vertical guide columns. A handrail and a knee rail have opposite ends guided for vertical movement in the columns. A bottom rail is connected pivotally to the knee rail and hangs to a position below the knee rail when the knee rail is in the lower position. An actuator causes the bottom rail to pivot up as the knee rail is elevated.

The gate generally includes a gatepost, and a plurality of rails pivotally connected to the gatepost and having a plurality of posts hingedly attached thereto. Hinged attachment of the plurality of posts allows them to fold substantially parallel with the plurality of rails when they in the vertical position. The gate includes a unique lift system having a translating device in communication with a sprocket, wherein the lift system provides an adjustable force to rotate the plurality of rails from a horizontal position to a vertical position. The translating device generally includes a first end attached to the gatepost and a second end attached to one of the plurality of rails, wherein the adjustable force may be provided by a turnbuckle positioned there between. The gate may further include a ground anchor system that allows axial rotation of the plurality of rails about the gatepost.
