The counterweight system is used to balance the weight of the car, serving as the "balance weight" of the elevator. It can reduce the load on the traction motor, improve the efficiency of elevator operation, and lower the energy consumption of the motor. The core components include the counterweight frame, counterweight blocks, and counterweight guide rails.
- Counterweight frame: As the supporting framework of the counterweight system, it is used to fix the counterweight blocks. The structural strength of this frame directly determines the stability and safety of the counterweight system. The counterweight frame produced by Zhejiang Jutuo Technology is made of high-strength steel welded together. It undergoes strict flaw detection to eliminate welding defects and optimizes the framework design to adapt to the shaft dimensions of different specifications of elevators, allowing for flexible matching of various counterweight blocks, balancing stability and versatility, and suitable for various scenarios in commercial and household elevators.
- Counterweight Block: The core counterweight component of the counterweight system, usually made of cast iron or concrete, precisely weighs according to the rated load capacity of the elevator to ensure effective balance of the car weight (generally weighing 40%-50% of the car weight). Jituo Technology's counterweight blocks are produced in a standardized manner, with a weight error controlled within ±1%. The surface is treated for rust prevention, making it resistant to rust and deformation. At the same time, custom-shaped counterweight blocks can be provided according to customer requirements, suitable for special installation environments such as small-sized shafts.
- Counterweight guide rail: The core component that guides the smooth up and down movement of the counterweight, similar in structure to the car guide rail, but focusing on adapting to the running path of the counterweight to prevent it from shifting, shaking, and avoiding friction with the elevator shaft components. The counterweight guide rail produced by Jutuo Technology adopts a high-precision cold rolling process, with a high surface smoothness and good straightness. It is fixed with a dedicated guide rail bracket and is easy to install. At the same time, it is equipped with wear-resistant guide shoes to reduce running noise and extend the service life of the counterweight system. It is supplied as a complete set with the company's counterweight frame and counterweight blocks, enhancing the overall adaptability of the counterweight system.
- Counterweight guide shoes: Installed on both sides of the counterweight frame, they closely fit the counterweight guide rails, functioning as a guide and buffer. They reduce vibrations and noise during the operation of the counterweight, ensuring that the counterweight runs synchronously and smoothly with the car. Jutuo Technology's counterweight guide shoes are made of wear-resistant rubber and are fixed with metal brackets. They have excellent buffering performance and wear resistance, and can be customized with suitable models according to the operating speed of the elevator, suitable for high-speed, medium-speed, and low-speed types of elevators.
