Its frame component is the core of the elevator car bearing structure, equivalent to the "skeleton" of capsules, to undertake all the car body weight (including passenger and cargo), and transfer the weight evenly to the traction system, the structure stability, the intensity is directly decided the elevator safety performance and service life of the capsules, is one of the giant Rio tinto in zhejiang science and technology at the core of the flagship product, Covered under the car frame liang, a full set of components such as beams, columns, bars, relying on the company patent technology formed differentiation advantage.
- Car frame upper beam： Located at the top of the car frame， it is mainly used for installing the counterweight pulley， traction rope fixation device， and car top guardrail. It is a key component connecting the car frame and the traction system. Jutuo Technology's car frame upper beam adopts an integrated stamping forming process. Compared with the traditional welded upper beam， it reduces welding deformation， improves structural accuracy and load-bearing capacity， and also reserves standardized installation interfaces， which can quickly adapt to different specifications of counterweight pulleys and traction ropes， meeting the installation requirements of the company's press-bolted car top structure， and improving the overall assembly efficiency.
-Underframe beam: It is directly connected to the car base and bears the load pressure at the bottom of the car. At the same time, it installs components such as car door drive devices and guide shoes. It is the foundation for ensuring the smooth operation of the car. Jutuo Technology combines the "Composite Type Car Base Based on Press Riveting Connection" patent technology to optimize the structural design of the underframe beam. It adopts a press riveting + welding composite process, which not only ensures a tight connection with the car base but also avoids welding deformation. At the same time, it adds reinforcement rib layouts to enhance the impact resistance of the underframe beam, meeting the requirements of different load capacities (0.5t - 5t) of elevators.
-Carriage frame column: A vertical supporting component that connects the upper and lower beams of the carriage frame, serving to bear the longitudinal load and fix the carriage body. Its verticality and structural strength directly affect the running stability of the carriage. The carriage frame columns of Jutuo Technology are made from high-precision seamless steel pipes through cutting and processing. The verticality error is controlled within 0.5mm, and the surface is treated with electroplating anti-rust treatment, which can adapt to complex shafting environments such as dampness and high dust. At the same time, the length can be customized according to the size of the carriage, suitable for different scenarios such as commercial elevators with large carriages and household elevators with small carriages.
-Carriage pull rod: A component that assists in fixing the carriage structure, used to enhance the overall rigidity of the carriage and prevent it from shaking or deforming during elevator operation. It is particularly suitable for the operation requirements of high-speed elevators. Jutuo Technology's carriage pull rods are made of high-strength alloy steel and have undergone tensile stress tests, capable of withstanding long-term repeated tensile impacts. They are also equipped with adjustable joints, which facilitate the adjustment of the carriage's levelness and verticality during installation, reducing the installation difficulty and forming a synergy with the company's complete carriage components to ensure that the overall performance of the carriage meets the standards.
