WELLD WSE1720-10 Tower crane total rated lifting load
  1. The Lifting Load data given in the table are the maximum lifting capacity when the crane is set up on firm and level ground. The load is not exceeding the load of 75% of the tipping load.
  2. The total rated lifting load indicated in the table includes the weight of hook block and slings.
  3. The working radius given in the table are the actual values including the deflection of boom under load, so lifting operation should be carried as per the radius.
  4. The 75% of the tipping load takes into account wind force 5, i.e. , lifting operation still can be carried on with full-extended outriggers when wind pressure exceeds 70N/m.

Control box
WELLD Remote control business
  1. WELLD Self-erecting cranes include two wireless remote control and wired remote control operation modes, which improves the users's operating comfort and safety.
  2. Force limit control system is included. With the help of various signal sensors, the torque limiter can monitor the various working conditions of the crane and provide the crane operator with continuous, real-time display of the crane operation status. The torque limiter can provide the operator with information about the working range, rated weight, actual weight and other aspects of the tower crane.
  3. The hydraulic outrigger adopts the dual safety protection of hydraulic lock and mechanical lock, which can effectively solve the danger caused by hydraulic internal leakage to the work due to the long-term use of the outrigger.
  4. The controller is controlled by Siemens PLC. Reliable, flexible and easy to operate.
  5. WELLD Self-erecting cranes are equipped with an anemometer, which can be banned when the wind speed exceeds the working requirements through the control system. Stop dangerous actions.
  6. Fast erection speed, good adjustment performance, stable work and high efficiency. The self-erecting crane boom and tower body are quickly erected by the hydraulic cylinder and the lever mechanism of the balance system, and quickly enter the working state.
  7. The hoisting mechanism uses a 3-speed motor, which can realize three kinds of speed control through a remote control and a torque control system, which can realize slow and stable start and stable and accurate load in place.
  8. The luffing mechanism adopts a 2-speed motor, and the double luffing speed is controlled by the remote control handle and the torque control system.
  9. The slewing mechanism adopts a planetary reducer and is equipped with a hydraulic coupling. It has a high load carrying capacity and adopts frequency conversion control. The starting and braking are stable and the work is reliable.
  10. WELLD Self-erecting cranes are equipped with safety devices such as lifting limiter, amplitude limiter, torque control system, tower crane swing brake, etc. to ensure safe and reliable work.
  11. The whole machine adopts a foundation-free design and is supported by four movable legs and hydraulic outrigger cylinders.
  12. The operation is fast, safe and reliable, and the installation cost is reduced.
  13. WELLD Self-erecting cranes come with front and rear tires can achieve rapid transition, improve work efficiency.
  14. The tower and boom by WELLD are made of high-strength steel, whichisstableandreliable
