1. Usage and Model Meaning QT1B-â–¡â–¡â–¡/â–¡-â–¡ series crane control console is mainly used for AC main circuit and control circuit of 50HZ rated voltage 380V and below and DC voltage 220V and below to control lifting and transportation machinery. Motor starting, speed regulation, braking and commutation in electrical control equipment with similar conditions.
The meaning of the model and representative are as follows:
2. Classification 2.1 According to the controller combination:
According to the number of controllers; full cam console; hybrid console;
2.2 According to the number of controllers: two controller console; three controller console; four controller console; five controller console; six controller console;
2.3 points fixed: fixed console; rotary console. Rotary consoles are more widely used in applications such as gantry cranes.
3. Structural features and operation principle The console is mainly composed of left and right control boxes, seats and bases. The operating box has two kinds of specifications: four mechanisms and six mechanisms (four mechanism boxes can hold four controllers, and six mechanism boxes can hold six controllers). The height of the seat, the inclination of the front and rear backrests can be adjusted freely, and can be folded and flipped to make the walks clear. The left and right control boxes and seats are installed on the base or directly mounted on the chassis of the cab. Easy to repair.
Each contact group of the controller in the console adopts double break point contacts and has a good arc extinguishing device. The contact groups are combined in the form of interpolation rhyme, and the arrangement is reasonable, so that the leads, wiring, and maintenance are better.
Console handle operation is flexible, reliable, positioning is obviously accurate, and has a zero position self-locking device, zero-seven-bit position self-locking with two functions, namely lift the self-locking rod before normal operation; Lift the self-locking rod After the handle is rotated 15°, it will remain unlocked and self-locking will be restored after restoration to ensure safe driving or parking.
The rotating console adopts a rotating device to rectify the order console with the foot in the range of 120° (that is, 60° left and right), and stays at any angle to ensure that the operator has a direct line of sight and does not leave dead angles.
4, technical data 4.1 Console for the following working conditions a, ambient air temperature, the upper limit +40 °C, lower limit -5 °C, the average value within 24 hours does not exceed +35 °C;
b. The air at the installation site is clean. The relative humidity does not exceed 50% at the maximum temperature of +40°C. The relative humidity at lower temperatures can be increased.
c. The altitude of the installation site does not exceed 2000m;
d, vertical installation, the inclination does not exceed 5 °;
e. The quality of the power supply network is qualified, and the line voltage fluctuation range cannot exceed ±10% of the rated voltage.
f, the console pollution level is 3, the installation category is III;
g. The protection level of the console shell is lp30.
4.2 The basic parameters of the console:
a, rated voltage: AC is 380V, DC is 220V.
b. The rated operating current of the main circuit of the console is 32A and 63A, the rated current of the auxiliary circuit is 2.6A, the agreed heating current is 10A, and the rated current at the time of the direct current is 0.4A.
4.3 The rated operating frequency of the console:
a. The main order is 1200 times/h.
b. The cam is 600 times/h.
4.4 The console is a repeated short-duration system with a rated power continuity rate of 40%.
4.5 Handle operating force when the console operates a single controller:
a, 10A is not more than 25N;
b, 32A is not greater than 40N;
c, 63A is not more than 50N.
4.6 Mechanical life and electrical life of the console 4.6.1 Electrical life The electrical life of the main circuit contact of the console shall comply with the requirements of the AC-2 use category, and the electrical life of the contact of the control circuit shall comply with the AC-15, DC-13 use category. Claim.
4.6.2 Mechanical Lifetime The mechanical life of the console is 1.5 million times for each controller and 3 million times for the linkage operation mechanism.

6. Transportation and storage conditions 6.1 During transportation and storage, it should be protected from rain and snow. The storage location should be air circulated and dry.
6.2 During transport and storage, the console temperature conditions are -25~+55°C, and (24h) the temperature can reach +70°C.
