• Which lift is better, with a machine room or a machine room-less?

    In modern world, the development of the lift industry is rapidly evolving not only through innovative technologies, but also through the development of standards for the safety of lift equipment. Paying attention to each specific project, it is necessary to take into account not only the technical and economic aspects, but also the wishes of the customer regarding the design and integration of the lift shaft in the space of the building.
    In most cases, it is better to use machine room-less lifts in general purpose buildings with low storeys and little space. As for multi-storey residential buildings- everything depends on technical and economic factors, because machine room-less lifts usually with a travel height above 35-45 meters (depending on the manufacturer and model of the lift) increase in price significantly.

  • Hydraulic vs traction lift. Which one is better?

    At the beginning of the 2000s, the era of hydraulic passenger lifts was replaced by traction machine room-less lifts. The main components of the electric lift, such as a sheave and a motor, have become significantly cheaper. Also, innovative solutions of lift equipment manufacturers have allowed to place the equipment in the lift shaft as compactly as possible. But there still are architectural features of the building, where the use of a hydraulic lift is the only possible solution. For example, in ultra-narrow and shallow lift shafts, the technical and economic properties of the facility should be taken into account for freight lifts, as low-rise and high-capacity can lead to the choice of hydraulic lift. But you should also pay attention to the fact that hydraulic lifts usually have restrictions on travel height up to 21 meters, speed up to 0.62 and 60 starts per hour (technical data depends on the manufacturers of a hydraulic equipment).

  • Safety components for lifts

    Safety components influence both the choice of the manufacturer of a lift and the confidence in stable further operating. Safety components for lifts according to the technical regulations of lifts include: 1.Devices for locking landing doors.  2.Safety gear to prevent falls, to prevent the car from falling or moving uncontrollably 3.Overspeed governor. 4.Buffers. 5.Electric safety devices in the form of electrical safety circuits containing electronic components. Manufacturers of safety components are usually separated from the lift industry, but there are cases where there is an integrated approach. Some of these components work only in emergency situations, but there are those that work during normal operation of the lift. These include, for example, devices for locking landing doors, where the operating time of the lock of the shaft door must be provided for at least 1 million operations. The same applies to the electric safety devices of electrical circuits.

  • Lift traffic analysis

    Lift traffic calculation is one of the most difficult parts of engineering a vertical transport section. It directly affects the comfort and convenience of operation of the building and the status of the object in general . Calculation of passenger traffic for office buildings, hotels, etc. Is performed by specialists using special software. The calculation of passenger traffic is performed by the data selection method. They choose the best option that satisfies both architects - according to the results of waiting for the lift, travel time, peak loads, and customers - for the needs of the optimal number of lifts, the criteria of their capacity and speed. From our experience, such a sequence is a priority - the number of lifts, their capacity and speed.
