Console for QT21 Crane
Standards
- GB/T 14048.1 General Requirements for Low-voltage Switchgear and Controlgear
- GB/T 14048.5 Low-voltage Switchgear and Controlgear – Part 5 – 1
- JB/T 6748 Consoles for Cranes
Scope of Application
This product is mainly used in control circuits with an alternating current of 50 Hz (60 Hz) and a rated voltage of 380 V (440 V) or below. It is designed to control the starting, speed regulation, braking, reversing, and other special functions of motors in hoisting and conveying machinery, enabling the linked operation of dual mechanisms. All types of integral consoles can be made into rotary ones. Different seats can be selected according to different usage environments. This series of consoles have been widely applied to various types of mechanical equipment in industries such as ports, water transportation, railways, metallurgy, mines, power, and construction.
Structural Features
This series of crane consoles is available in both integral and split types. The outer shell components of the products can be formed by stamping metal materials or injection – molding engineering plastics, featuring an attractive appearance.
The crane consoles are equipped with various models of master controllers developed by our company, providing a comfortable operation experience with a distinct tactile sensation and clear gear positions.
The operating mechanism is provided with an automatic reset and zero – position self – locking device. The contacts use Schneider contacts and self – made contacts, ensuring safe and reliable operation and a long service life.
The wiring, installation, and maintenance of electrical components are convenient. The crane consoles are equipped with various indicator lights and control buttons, and it is easy to install additional devices such as touch screens and mimic panels.
The seats have adjustment functions for height, forward – backward position, backrest angle, and weight adaptation, which can meet the comfortable operation requirements of people with different body types.
