Guide rail parts

Guide rails are one of the important parts in the elevator shaft system , designed as vertical columns along the height of the shaft. The main function of this system is to shape and guide the cabin and counterweight to move in the correct design trajectory, preventing displacement or deviation during operation. This not only ensures stability but also enhances the safety of the elevator when in use. The guide rail system is made from high-strength, high-strength materials, helping to increase reliability and prolong the life of the entire elevator system. In addition, the installation of guide rails requires high precision to ensure that the cabin moves smoothly, without causing vibration or noise during operation. This is an essential factor contributing to the safety and comfort of elevator users every day.

Elevator cabin parts

The elevator cabin is one of the most important parts, designed to transport people or goods between floors in a building. Each elevator line has its own cabin design, suitable for the purpose of use and the characteristics of each project. Inside the cabin, the basic components are equipped with an automatic door system or a manual door, a sturdy cabin floor, a control panel with integrated buttons to select floors, and many accompanying accessories such as handrails, lighting, or mirrors to create a more spacious feeling. All of these elements are installed and completed to ensure the most comfortable, safe and convenient travel experience for users. The cabin design focuses not only on function but also on aesthetics, with many options for color, material and style to suit each architectural space.

Elevator counterweight

The elevator counterweight plays an important role in balancing the mass of the cabin system, usually designed to be about 50% of the maximum elevator load. This not only helps reduce the pressure on the motor but also optimizes the performance of the system. At the same time, the counterweight also creates a stable friction force between the pulley and the cable system, thereby ensuring that the elevator motor operates more smoothly and efficiently. The correct design and installation of the counterweight not only contributes to prolonging the life of the elevator but also improves the safety level during operation.

Basic dimensions of elevator shaft

The size of the elevator shaft is often flexibly designed, depending on the specific characteristics of each project and based on many different factors such as elevator type, load, and installation space.

Technical specifications and notes when constructing elevator shafts

To ensure safety and high accuracy when constructing elevator shafts, homeowners need to clearly understand some important technical parameters and notes. First, the elevator shaft center must be positioned accurately, with a maximum deviation of no more than 10mm. At the same time, it is necessary to ensure that parts such as the machine room, elevator shaft, and PIT are always dry, not permeable to water or affected by rain.

During construction, the symmetry axis on both sides of the elevator shaft must be strictly controlled, with the width not exceeding +40cm and -20cm. The symmetry axis of each floor compared to the vertical axis at the center of the elevator shaft must also ensure that the deviation does not exceed 10mm. For pouring U-shaped beams to install guide rails, it is necessary to follow the design drawings, each beam step has a distance of 1600mm, to ensure the guide rail system operates stably.

In addition, the concrete pouring in the elevator shaft system must meet the load-bearing standards such as R1, R2, ... R7 to ensure durability and safety when operating the elevator. The batket beam for the floor door must be poured at all stops, with a standard size of 20cm x 20cm, and must be directly connected to the column according to the design drawing. Another important note is that when constructing the elevator shaft wall system , it is necessary to leave the floor call position according to the size specified in the drawing, this size may vary depending on the specific elevator type. The above notes not only help optimize the construction process but also ensure safety and quality when putting the elevator into use.
