Description
Diagram of an electric talfer.
The three-phase voltage of the network through the switch and fuses Pr1-Pr3 is connected to the drive motors AD1 hoist (using the contacts of the magnetic starters of the rise of the gearbox or the descent of the CS) and the mechanism of movement of the AD2 telfer (using the contacts of the starters forward KB or backward KN). An electromagnet TM is connected to the pins of the stator AD1, which dilutes the brake pads as soon as a voltage is applied to the stator. The upward movement of the cargo suspension is limited by the final switch of the BCP. The circuit provides for blocking from the simultaneous activation of the reversing starters of each engine by double-circuit buttons and opening contacts. The mechanisms of the telfer are controlled from the floor with the help of a button post suspended from the telfer. For the operation of the engines, it is necessary to continuously press the corresponding button, which does not allow the operator to move away from the push-button station and requires careful monitoring of the operation of the telfer.
