How many tons of cranes must be installed torque limiters?
When the actual payload is 90% of the rated load, the display "normal" lights are on; When the actual load reaches 90% of the rated load, the display "90%" lights and the buzzer on the torque limiter is starting to alert the buzzer. When the actual load reaches 100% of the rated load, the display "100%" lights are on and the buzzer on the torque limiter is on the engine and the buzzer starts intermittently to call the alarm. When the actual load reaches 104% of the rated load, display the light is "104%", at the same time torque limiter sirens hosts a buzzer alarm, relay action, lifting, and an increase in working radius of crane boom operation will automatically stop, to prevent the driver made a mistake by mistake or rough operation by the accident.
For arm frame cranes, the main danger is instability. In order to guarantee the safety of lifting, the lifting torque should not exceed the rating. Hoisting mechanical safety regulations stipulate that the lifting weight is equal to or greater than 1, 6 tons of truck crane, wheel type crane, and the torque limiter. Lifting capacity is equal to or greater than 25t tower crane shall load torque limiter.
According to the gb6067-85 rule; The lifting capacity of a crane or crane that weighs more than 16 tons is greater than the equivalent of 25 tons of crane and the torque limiter should be set
Hoisting mechanical safety regulations stipulate that the lifting weight is equal to or greater than 1, 6 tons of truck crane, wheel type crane, and the torque limiter. Lifting capacity is equal to or greater than 25t tower crane shall load torque limiter
Torque limiter is to separate completely controlled by the computer security operating system, can automatically detect the crane quality and jib crane load by's point of view, and can show its rated load and the actual load, working radius, lifting beam Angle. Real-time monitor crane operating condition, built-in diagnostic function, rapid danger condition alarm and safety control. With the function of the black box, the operating condition of the operation is automatically recorded, which provides the basis for the analysis of the accident. By setting the parameters, the torque limiter can implement the following functions:
