One of the significant issues in civil structures is the transfer of loads and materials into the floors after the construction of the skeleton and roof of the building. Workshop lifts and tower cranes play an important role in this.
A workshop elevator is a device that is used to transport people and construction materials to high places and it is available in two types, single cabin and double cabin. The workshop elevator is installed on a mast in the external environment of the building and its dimensions depend on the user's demand, the number of floors and the area of each floor. The cabin is secured and covered with punchy sheets or fence netting. Common movement in this type of elevator is rack and pinion (stone and pinton), which is done with the help of this transfer system between floors. In this article, by introducing workshop elevator parts, we intend to introduce you to standard workshop elevator components. If you want to know what a workshop elevator is and howHow is the construction of a workshop elevator ? We suggest that you also read other articles on the Radasanat website .
Workshop lift classification based on structure
Fixed workshop elevator: Fixed workshop elevator is used in various industries such as transmission towers, bridges, tunnels, chimneys, coal transmission towers, silos, towers, power plants, communication towers, etc.
Mobile workshop lift: Mobile workshop lifts are used to move heavy objects. This type of workshop lift is used in the construction industry.
Types of fixed workshop elevators:
Use of elevators and workshop lifts:
Safety in the workshop elevator
The workshop elevator is used in high traffic places and the duty of the workshop elevator parts is to work properly together and help to transport and move heavy goods. Therefore, creating safety for different people, employees and load safety is of particular importance, so the safety equipment of all workshop elevators is of particular importance. Among the workshop elevator parts and their safety equipment, the following can be mentioned:
Protection around the workshop elevator
The task of guarding a workshop elevator is to maintain the access of people and equipment to the area of the elevator room, and this guard separates the space of the elevator cabin like a wall.
Workshop elevator omega fence
A fence is installed at the entrance and exit of people and goods from the elevator, which opens and closes by pulling up and down. This fence prevents the entry of people, cargo or objects into the elevator chamber and path.
Workshop elevator safety switches
Safety switches are installed at the beginning and end of the workshop lift. These switches are located on the elevator doors and prevent risks such as elevator falls.
Workshop elevator path limiters
Among the parts of the workshop elevator that lead to its safety are the limiters of the elevator path. This part helps the workshop elevator to prevent it from coming out of the guards and falling of the cabin if it does not stop while going up and down for reasons such as the laminate switch not working. These mechanical parts stop the movement of the workshop elevator.

In order to prevent the fall of the workshop elevator during the installation of the elevator, the emergency brake system of the workshop elevator or parachute is installed, and after it is installed, it is tested and its operation is taught to the workshop manager, etc.
One of the components of the workshop elevator is the guide rail. The part of the bracket or guide rail is the path through which the cage moves vertically and includes a mast that is connected with 24 x 230 bolts. The mast sections are made of seamless pipes, angle steel and other materials and racks, which are pressed onto the mast using three Allen screws.
Workshop elevator cage
A workshop lift consists of a cage in which people stand during transportation and a track that is installed into the building. The cage moves along this track using a rack and pinion drive system, and the cage can be stopped at various locations along the track. This allows people to unload at any floor along the way.
The track itself is usually made of steel and is bolted together. This makes the workshop elevator more stable and makes the construction process much faster and easier. These structures are usually temporary and make the transportation of parts controllable. The lift height varies depending on how many sections of track are secured to the building.
The cage part is made of mesh, structural steel, steel sheet, etc. Its upper part is connected to the driving system and the lower part of the cage is connected to the concrete delivery device. The main channel is equipped with guide rollers and safety hooks, and there are doors at the top, bottom, left and right.
Elevator concrete carrying machine
The concrete conveyor is also one of the components of the standard workshop elevator. The concrete hopper is connected to the elevator cabin using a roller pin and has a maximum volume of 0.7 cubic meters. The entrance of the hopper is directly facing the bottom door of the cage and the concrete is poured into the hopper through the door. The pumping speed can be increased or decreased by adjusting the inlet opening angle.

Workshop elevator rebar carrying device
The device includes a suspension system, rebar frame, rebar clamp, etc., and only when the device is unloaded, the rebar frame should be assembled.
The sub-frame and protective framework of the workshop elevator
The bottom layer is one of the parts of the workshop elevator, which is made by welding steel to steel plate and then it is connected to the concrete foundation of the building by using bolts and nuts to the guide rail bracket and using anchor bolts. The sub-frame is able to bear the full weight of the vertical load and transfer the load pressure to the concrete foundation.
Connecting devices or wall bolts for workshop elevators
The connecting piece refers to the connecting part between the guide rail bracket and the building and is used to maintain the strength of the guide rail bracket and also maintain its integrated structure.
Workshop elevator cable guide rail
This section is designed to support cables. The guide rail limits the cable to the protective environment of the rail and prevents the cable from connecting and sticking with the rest of the equipment during the elevator installation. Before installing the cable, the operator must ensure that the cable and the cable arm can hold the protective cable firmly without contact with the room.
Workshop elevator cable pulley system
When the workshop lift reaches a position of more than 150 meters, it is necessary to use a cable management system to help the voltage drop of the power cable and avoid the problems caused by the cable resistance.
Workshop elevator cable arm frame
This part is located inside the cage and is used to pull the cable so that it easily passes through the protective ring of the cable guide and reduces the risk of scratching or twisting the cable.
Workshop elevator mechanical system
This system is connected to the top of the cage by a roller and includes: a driving plate, a driving frame and three driving units.
Electrical system of workshop elevator
The last one of the most important components of the standard workshop elevator is the elevator electrical system. The workshop elevator can use VVF variable frequency speed control system and this system can continuously change the speed from 0 to 90 meters per minute. Also, this electrical system consists of upper and lower electrical cabinets, resistance box, work box, main control cable, different distances with limit switches, etc.
