QT1B- □□□ / □ - □Series crane console

1. Use and model significance

QT1B- □□□ / □ - □Series crane console, mainly for communication 50HZ Rated voltage 380VAnd below and DC voltage 220VAnd the following main circuit and control circuit to control the lifting of transport machinery and similar conditions of the electrical control equipment in the motor starting, speed, braking and commutation.
Model and the significance of the representative are as follows:

2. classification

2. 1, According to the controller combination:
By the number of points controller; full cam console; hybrid console;
2. 2, According to the controller number: two controller console; three controller console; four controller console; five controller console; six controller console;
2. 3, Fixed by the way: fixed console; rotary console. Rotary console is more widely used in gantry cranes and other occasions.

3. Structural characteristics and action principle

The console is mainly composed of left and right control box, seat and base, etc. The control box has two kinds of specifications: four bodies and six bodies (four units can be equipped with four controllers, The height of seat can be adjusted freely before and after, and can be folded and flipped to make the roadway smooth. The left and right operation boxes and seats are screwed on the base or mounted directly on the chassis of the cab. , Can be removed for easy maintenance.
Each contact group in the console uses double-break contacts, and has a good arc extinguishing device, the contact group using the form of interlocking rhyme combination, reasonable arrangement, so that wire, wiring and maintenance better.
The operation of the console by the joystick through the two sets of gear drive, you can achieve two controllers were driven and simultaneously driven the purpose of the handle of the export of dust sealed device, front, rear, lift operation position to meet the actual use Requirements 1-6The number of contacts is up to 23Only the installation of the upper part of the box attached to electrical components for control of crane movements of the various other signaling systems.
Console handle operation is flexible, reliable, accurate positioning, and has a zero self-locking device, zero seventy-eight bits of self-locking has two functions, namely, to lift the self-locking bar to normal operation; The handle turns 15 °After the maintenance from the self-locking, recovery after the restoration of self-locking, to ensure safe driving or parking.
Rotary console selection of rotating devices, reorganization order console with the chassis 120 ° (That is, left and right 60 °) Within the scope of the foot operation, any stop corner to ensure that the operator has a direct line of sight, leaving no dead ends.

4. Technical data
