Safety equipment

Abstract

A safety system includes a load detection sensor retrofitable on a safety hook, a transmitter arranged to convey a load status signal, processing means for analyzing the load status signal, a receiver for receiving the load status signal and being operably connected to the processing means, warning means arranged to generate notifications, and a power source for providing energy to the transmitter, the receiver, and the processing means. The load detection sensor is arranged to generate a load status signal which is sent by the transmitter to the receiver and then analyzed by the processing means so that when the load status signal indicates that a load is undetected or that the safety hook is connected, the warning means are either inactive or generate a first notification but when the pressure status signal indicates that a load is detected or that the safety hook is disconnected, the warning means generate a second notification.

1 . A safety system, comprising:
 a load detection sensor retrofitable on a safety hook;   a transmitter arranged to convey a load status signal;   processing means for analysing the load status signal;   a receiver for receiving the load status signal and being operably connected to the processing means;   warning means arranged to generate notifications; and   a power source for providing energy to the transmitter, the receiver, and the processing means;   wherein the load detection sensor is arranged to generate a load status signal which is sent by the transmitter to the receiver and then analyzed by the processing means so that when the load status signal indicates that a load is undetected or that the safety hook is connected, the warning means are either inactive or generate a first notification but when the pressure status signal indicates that a load is detected or that the safety hook is disconnected, the warning means generate a second notification.   
     
     
         2 . A safety system according to  claim 1 , wherein the load detection sensor is a pressure sensor. 
     
     
         3 . A safety system according to  claim 2 , wherein the pressure sensor is a piezoelectric sensor. 
     
     
         4 . A safety system according to  claim 2 , wherein the pressure sensor comprises quantum tunnelling composites. 
     
     
         5 . A safety system according to  claim 1 , wherein the load detection sensor comprises a cable operably connected to a first self-energizing switch arranged to be activated when the cable is in a pulled condition and second self-energizing switch arranged to be activated when the cable is in a relaxed condition. 
     
     
         6 . A safety system according to  claim 1 , further comprising a second load detection sensor retrofitable on a second safety hook. 
     
     
         7 . A safety system according to  claim 1 , wherein the warning means are adapted to generate a visual notification, an audible notification or a visual and an audible notification. 
     
     
         8 . A safety system according to  claim 1 , further comprising a timer arranged to generate an alarm after a predetermined time threshold has been exceeded. 
     
     
         9 . A safety system according to  claim 1 , further comprising a counter arranged to generate an alarm after a predetermined time threshold has been exceeded. 
     
     
         10 . A safety system according to  claim 1 , wherein the warning means is at least one LED light. 
     
     
         11 . A safety system according to  claim 1 , wherein the transmitter includes at least one self-energizing switch. 
     
     
         12 . A safety system according to  claim 1 , wherein the processing means, the receiver and the warning means are included in a beacon. 
     
     
         13 . A safety system according to  claim 11 , further comprising activation means. 
     
     
         14 . A safety hook comprising a load detection sensor and a plastics layer wherein the load detection sensor is retrofitted on the safety hook by shrink-wrapping the plastics layer with heat so as to secure the load detection sensor on the safety hook. 
     
     
         15 . A safety system according to  claim 2 , wherein the load detection sensor comprises a cable operably connected to a first self-energizing switch arranged to be activated when the cable is in a pulled condition and second self-energizing switch arranged to be activated when the cable is in a relaxed condition.
