The Automatic Crown Saftey Device (Crownomatic, Crown-o-matic safety device) is a safety aid installed on a drawworks drum to control the distance a traveling block may be pulled up into a derrick thus eliminating the possibility of pulling the traveling block into the crown. A toggle valve is mounted in a track (to allow adjustment) above the drawworks drum and toggle valve is actuated by extra line being wrapped on the drum. When the toggle valve is actuated the drum clutch on the drawworks is engaged and the mechanical brake is locked down by use of an air cylinder.
Installation of this device is very simple and may be installed on any existing drawworks. Installation may be made in the field with minimum downtime. Each unit comes complete with all necessary parts for installation, including hose and adapters. All that is needed is a welder.
The safety control system includes a stainless steel toggle valve with a stainless steel inter-liner in the air cylinder which helps eliminates corrosion from the H2 S gas and other corrosives.
