Hoisting Weight Limiter TCQ-M/B-4/1-20t
TCQ-M type lifting weight limiter, small size, easy installation, low price, suitable for all kinds of conventional series electric hoists. The instrument adopts a new digital circuit design scheme, combined with the programmable technology of the single-chip microcomputer, so that the instrument has a certain versatility, and the operation and debugging of the device are more convenient. The integration of intelligent processing technology in overload control can well eliminate false alarms and malfunctions caused by shock, shaking and other factors when the electric hoist lifts heavy objects in a critical state. In addition, the device also adds a black box function that automatically accumulates and memorizes overload times and a password protection function for correcting rated lifting weight parameters.
TCQ-M/B(Z)-“Magnification”-“Rated Lifting Capacity”-“Wire Rope Diameter”
Example 1: TCQ-M/B-2/1-10t-Φ18, with BCQ side pressure sensor, magnification 2/1, lifting capacity 10t, wire rope diameter Φ18mm
Example 2: TCQ-M/Z-4/2-20t, with ZX type shaft pin sensor, the magnification is 4/2, and the lifting weight is 20t.
Main technical parameters
