What are the components of a tower crane? What are the three main technical parameters?
The tower crane consists of metal structure, work mechanism and electrical system. The three main technical parameters are lifting torque, lifting weight and working speed. The lifting torque refers to the product of the largest amount of weight when the heavy arm is the base arm, or the maximum weight and the corresponding inflection point.
Tower crane has a good safety device, such as lifting weight limiter, amplitude limiter, height limiter and the load moment limiter device such as a limit, as well as the lead limit switch, tower lights, sonde, windproof clip rails, the ladder insulation ring, aisle guardrail, etc. The driver's room requires comfortable, convenient operation, good view and complete communication equipment.
Tower crane, also known as tower crane, originated in Western Europe. The moving arm is mounted on a rotating crane at the top of the tower. The operation space is large, mainly used for the vertical and horizontal conveyance of the material in building construction and the installation of building component. It consists of three parts: metal structure, work mechanism and electrical system. The metal structures include the tower, the arm and the base. The work body has four parts: rising, changing, turning and walking. Electrical systems include motors, controllers, power distribution cabinets, wiring, signals and lighting fixtures.
Components: the base, the tower, attached device, excessive section, jack-up mechanism, slewing mechanism, the lifting mechanism, jib, balance arm, electric control, safety protection devices, etc. Main technical parameters: maximum weight, amplitude, maximum weight Lifting torque = amplitude X maximum weight
