FIELD: measurement technology; devices for determination of angles of inclination of cargo hoisting machines. SUBSTANCE: warning unit includes inclinometer and alarm. Inclinometer body is made from dielectric; it consists of two identical and symmetrical units which are filled with oil to definite level. Each unit has three electrodes located in horizontal plane and brought in contact with surface of oil. At one end, electrodes are articulated on body and other ends are movable. Electrodes have contacts of different height in vertical plane. These contacts are made for alternating closing with respective fixed contacts. EFFECT: increased number of angles under test; enhanced ecological safety and simplified construction. 2 dwg
