Abstract
A scaffold safety device (120) has a body (122) having an engagement formation (124) configured to engage with an element (20, 72) of a scaffold assembly (10). The device (120) also has a pressure sensor (126) configured to detect when the body is disengaged from the scaffold assembly. The engagement formation includes first and second arms (128, 130) extending away from the body. The arms are separated by a cavity (134). The cavity is configured to receive a threaded rod and a tightening nut (135) of the scaffold assembly. The pressure sensor is included on one arm (128) and is configured to detect when a pressure attains a predetermined threshold value. The pressure sensor is in communication with a control board (86) which is connected to an antenna (140) on a secondary scaffold safety device (142).
Claims8
A scaffold safety device comprising a body having an engagement means configured to engage with an element of a scaffold assembly, and a sensor configured to detect when the body is disengaged from the scaffold assembly;
- wherein the engagement means includes first and second arms extending away from the body, the arms being separated by a clearance, the clearance being configured to receive a threaded rod and a tightening nut of the scaffold assembly;
- wherein the sensor is a pressure sensor, and at least one of the first arm, the second arm and a portion of the body located between the arms, include the pressure sensor which is configured to detect when a pressure attains a predetermined threshold value;
- wherein the pressure sensor is included in the first arm.
