1. The lifting and rotating mechanism adopts variable frequency speed control, ensuring smooth starting and braking.
2. The main structural components of the tower crane are made of low-alloy steel materials to improve its low-temperature resistance performance.
3. Adopting large-diameter external tooth meshing rotary bearings for more stable rotation;
4. Multiple arm length combinations to meet different user needs.
The standard section is an integral structure connected by fishplate pin shafts, with high machining accuracy and easy installation and use. It is interchangeable with the L46 standard section and is equipped with a large platform inclined ladder for safety and convenience.
The tower crane foundation adopts a four legged design, which is used in conjunction with the overall standard section to ensure the horizontal and vertical alignment of the foundation.
The standard section adopts the method of introducing small cars to improve the stress situation of the slewing support and slewing mechanism, and extend the service life.
Two sets of rotating mechanisms are symmetrically arranged, using variable frequency motors and variable frequency drives for speed regulation, ensuring reliable operation and smooth starting and braking.
The electrical control cabinet and resistance box are both made of stainless steel, which has good corrosion resistance; All electrical components are sourced from well-known domestic and international brands, ensuring reliable quality.
