Latest Patents

Mitsui's latest innovations include two noteworthy patents. The first, titled "Elevator Having Rope Guide Means," features a sophisticated design that incorporates a rope vibration suppressing device. This device is strategically located on the floor of the machinery room, atop the elevator cage, or at the top portion of the balancing weight. Its primary function is to prevent lateral vibration of ropes that may occur during lateral motion of the building in which the elevator operates.

The second patent, "Scaling Device for an Elevator Car," showcases his dedication to safety. This innovative scaling device measures the load on the elevator car floor to avert overloading. By detecting the deformation of rubber insulators mounted beneath the car floor, the device ensures that the load remains within safe limits. Load detecting beams beneath the car floor identify the deformation, and when the load surpasses the rated capacity, a load detecting switch activates, ceasing the car's operation.
