    Tips: Applications of heavy duty limit switch

    1. Cement pump truck
      Cement pump trucks have long articulated arms or rods that can transport concrete to locations where ordinary cement tankers or pumping machinery are difficult or unreachable. Heavy duty limit switches are used to detect the position of the beam. The limit switch sends a signal to the operator when the beam is properly seated.
    2. Off-highway dump truck
      Off-highway heavy duty dump trucks are usually equipped with an open compartment or dump truck that is hinged to the rear of the truck. These trucks experience very strong vibrations and shocks during normal operation. In addition, these trucks need to work in extreme weather conditions such as heat, cold, dust, corrosive chemicals, rain and wind. The heavy duty limit switch detects that the dump or the container is fully seated or not on the truck's chassis. This signal is fed back to the control system to provide an indication to the truck operator.
    3. Planter
      The planter is usually connected to the rear of the farm tractor by a pull roller, thus needing to withstand the strong vibrations and impacts caused by the tractor and the dry, hard, uneven fields.
      Two roller lever limit switches can be used to monitor the position of the planter's tracker arm, and another heavy duty limit switch is used to monitor the on/off status of the pneumatic system.
    4. Harbor bridge crane
      Harbor bridge cranes are very expensive equipments that can be costly to repair or replace if damaged. Moreover, business downtime caused by equipment damage can also result in thousands of dollars in losses. Therefore, it is important to conduct a comprehensive inspection of the various mechanical connections and accessories of the harbor bridge crane, to ensure efficient and precise operation and control. Another important standard for customers in the port crane business is the overall reliability of the system and the safety of workers. The heavy-duty limit switch can be used to detect the position of the crane cab during motion and to detect the switch status of various doors on the crane and the operating status of the inner track.
