QT1B-□□□/□-□Crane series console

1. Purpose and type meaning

QT1B-□□□/□-□Series crane console, mainly for Exchange 50HZ Rated voltage 380VAnd below, and DC/DC 220VAnd below the main circuit and control circuit, the control of hoisting and conveying machinery and electrical control equipment of similar conditions in the motor starting, speed, braking and directional control.
Type and meaning of is as follows:

2. Classification

2. 1According to controller combinations:
By the number of controllers; Cam console; Mixing console;
2. 2, By the number of controllers: two controllers to the console; Three controllers console; Four controllers console; Five controllers console; Six controllers console;
2. 3At a fixed point: stationary console; Turn the console. Turning console more widely used for gantry cranes and other occasions.

3. Structure and operation principle

Console is composed of left and right control box, seats and seat components. Control box has four and six bodies in two sizes (four-body enclosure holds four controller, six agencies box fits six controllers). Seat height of backrest inclination can be freely adjusted, and can be folded, turning passages, around the control box and seats were installed with screws on the base or directly in the driver's cab on the chassis, can be removed to facilitate maintenance.
Console controllers in the contact group were treated with double-break contacts, and have a good arc-control device, the inserted vowel combinations in the form of the contact group, arrange reasonable, leads, wiring and maintenance is a plus.
Joystick console operation through two sets of gear, you can achieve the purpose of two controller, drive and drive at the same time. Exit fitted with sealing of the handle system, left and right, elevating operation position to meet the actual requirements are divided into the 1-6Stalls, contact up to 23Only, on the box cover to install some additional components and other actions to control cranes of various signalling system used.
Console handle with flexible, reliable positioning clearly accurate, with zero locking device, 078 broken lock has two functions, that is, lift the locking lever for normal operation; Lift the lock lever the handle rotation 15 °Keep out of the lock, recovery recovery self-locking to ensure safe driving or parking.
Rotational selection console turn table, rectify order in the console with the chassis 120 ° (That is, each 60 °) Range with foot control, any travel angle to ensure operators have a direct line of sight, leaving no dead ends.

4. Technical data

4. 1Console applies the following conditions
