Safety device for bridge and gantry cranes ONK-160 M
The principle of operation and description of the components of the ONK-160 M.
The safety device ONK-160 M is the most common device for bridge and gantry cranes in the Russian Federation. What is he like?
The ONK-160 M necessarily includes the BU-06 control unit, a signal cable (harness) and from one to eight force sensors. On request, the structure can additionally include an expansion unit and a wind speed sensor with its own cable.
The BU-06 control unit is a microprocessor unit that receives digital information from the device's sensors and processes it in accordance with a given program. It is in the control unit that all service information for the crane is entered: load characteristic, type of load gripping device, number of lifting mechanisms, date of installation of the crane safety device, serial number of the crane.
In addition, the control unit includes output relays to shut down the crane hoist drive in case of overload and a built-in recording element of operating parameters (black box).The information stored in the parameter recorder can be read through the infrared port to the STI-3 reader for further processing on a personal computer.
The BR ONK-160 M extender is designed to accept additional discrete signals. Such a signal could be, for example, a signal that a freight cart is leaving the console. This can be useful if the lifting capacity of the cantilever gantry crane is different from the main lifting capacity.
The wind speed sensor is mounted on the highest point of a gantry crane or transfer crane and reports the current wind speed to the device.
The ONK-160 M protective device has been produced by the Arzamas Electromechanical Plant for almost a decade, and yet it is still popular with regulators and specialists in the operational maintenance of protective devices for lifting machines.
