Stationary geophisical winches
Description
Stationary geophysical winches are designed for lowering and rising operations with a cable on control-testing wells at distant and difficult to reach areas where use of mobile winches is not possible; for work as a part of marking installations and winding machines at repair plants.
Control system and electric drives depending of purpose provide:
- smooth speed change of movement of cable;
- automatic record of logging parameters;
- visualization of length (depth);
- speeds of movement and tension of cable;
- automatical control of linear speed of cable movement;
- smooth tension change by winding to stationary winch;
- ordered cabling of different diameter;
- setting limit values of tension and length (depth);
- alarm reel stop of winch;
- sound signal when given limit value of length (depth) and tension are reached with possibility of automatic stop;
- possible PC connection with registration of winding parameters (speed, length, tension, crossing magnetic label).
Specifications
Electric drives of stationary winches of marking installations with power over 30 kWcan provide additionally:
· smooth change of tension by take up and pay off a cable;
· automatical tension control is possible;
· automatical tension control depending length of a cable is possible.
