What is karsing and why is it important in the elevator industry?
Types of karsing in hydraulic systems
- Direct karsing (Direct): In this model, the jack is directly connected to the yoke. It is usually used for low heights and heavy loads.
- Indirect karsing (Indirect): In this method, which is very common, the jack applies power to the karsing through the towing wire and the junk plate. This system makes the speed of the cabin double the opening speed of the jack (2:1 system).
- L-Shape carring: It is one of the most popular models in home lifts and hydraulic elevators. In this model, the rails are only on one side of the cabin, and the L-shaped carring holds the cabin. Accurate installation of this model is one of the main specialties of our technical team, and observing important points of carring installation in Pars Shiraz lift industry in L-shaped models has double sensitivity.
The basic installation steps of Karsing by the team of Pars Lift Industry
1. Examination and preparation of the well
2. Assembling karsing parts (upper and lower yoke)
3. Installing a parachute (safety brake)
detailed settings and regulation; The difference between professional and amateur work
Physically installing the parts is only half the way. What determines the final quality of the elevator movement is the precise adjustment or the carring adjustment. In the discussion of the important points of installing karsing in the lifting industry of Pars Shiraz, Regalage has a special place.
If the carring is not centered in relation to the rails, the cabin will suffer from lagging or wear. This causes annoying noises and corrosion of the shoes. By using laser plumb bobs and accurate measuring tools, Pars lifting industry experts make sure that the karsing is located exactly in the center of gravity of the well. Also, in indirect hydraulic models, it is very important to adjust the tension of the towing wires on the karsing plate. If the tension of the tow wires is not the same, the sheet will suffer asymmetric wear.
The importance of leveling the cabin platform
Carsing is the base on which the cabin floor is placed. One of the important points of installing karsing in the lifting industry of Pars Shiraz is the complete alignment of the lower yoke. If the lower yoke has even a few degrees of inclination, the cabin floor will also be tilted and the passengers will feel unsafe. In addition, the tilt of the sole causes asymmetric pressure on the shoes and rails. In all installation projects in Shiraz, after the initial installation, we perform several level test steps to make sure the support surface is flat.
The role of shoes and shock absorbers in karsing installation
In order to have a smooth and silent movement, it is necessary to use suitable shock absorbers between the cabin and the car. These shock absorbers (Rubber Mounts) absorb the vibrations caused by the movement of the jack or the engine and prevent it from being transferred to the cabin. In the list of Important tips for installing karsing in the lifting industry of Pars Shiraz, choosing the type and hardness (Shore) suitable for these tires is very emphasized.
Challenges of installing karsing in L-Shape systems
As mentioned, L-shaped carrings are very widely used in hydraulic elevators. But installing them has its own challenges. In this system, because the power enters from one side (the side of the rails), there is a tendency for torque and tilting of the cabin.
One of the most important points of installing karsing in Pars Shiraz lifting industry in L-shaped models is the extremely high strength of the karsing structure and precise adjustment of guide shoes. The distance between the upper and lower shoes in this model should be as large as possible to increase the torque arm and increase the stability of the cabin. The engineers of Pars lifting industry design the best height for the yoke with precise engineering calculations, so that the maximum stability and balance can be provided despite the limited space in the manhole. It is the technical subtleties that distinguish our services in Shiraz.
Karsing material and quality
No matter how high the quality of the installation is, if the karsing part itself is made of poor raw materials, it is of no use. In Pars Lift Industry, we closely monitor the quality of steel sheets and profiles used in the construction of cars. Karsing weldings must be in accordance with industrial standards and there should be no cracks or bubbles in the welds.
During the installation, checking the physical health of carsing is one of the important points of installing carsing in Pars Shiraz lifting industry. Any bending in the profiles can lead to the elevator getting stuck. We test it in the quality control workshop before transferring the carring to the project. Electrostatic or galvanized paint coating is also necessary to prevent rusting in wet weather (which is sometimes present in wells).
Final tests and delivery
After fully installing the karsing and mounting the cabin, it is time for dynamic and static tests. At this stage, weights equivalent to the nominal capacity and even more are placed inside the cabin to measure the karsing resistance and the performance of the parachute.
One of the important points of installing karsing in Pars Shiraz lifting industry is to perform parachute test with full load. In this test, the cab is moved down at high speed and the safety brake is activated. Karsing must be able to withstand the shock of sudden braking without any permanent deformation. This final test is a seal of approval on the quality of work of the technical team of Pars Lift Industry. It is only after the success of these tests that the elevator will be delivered for residents to use.

Dangers of unprincipled installation of karsing
Unfortunately, it has been seen that some non-experts ignore the important points of carring installation in Pars Shiraz lift industry in order to reduce costs or increase the speed of work. The consequences of this negligence can be very expensive:
- Loose noise: Loose connections cause squeaking and knocking noises when moving.
- Cabin vibration: Inaccurate adjustment of shoes and rollers causes annoying vibrations.
- Premature failure of rails: Asymmetric pressure of carsing causes severe wear of elevator rails, which are very expensive to replace.
- Parachute not working: If the parachute is installed on a slanted karsing, it may not work at the moment of danger and cause a disaster.
Pars Lift Industry Co., being aware of these risks, never sacrifices quality and safety for speed. For us, the life and safety of Shirazi customers is the first priority.
Periodic maintenance and inspection of karsing
Correct installation is not the end of the job. As a component that is under constant stress, the carring needs periodic inspection. In the monthly services of the Pars lift industry, our technicians check the condition of the karsing bolts and nuts. Possible hairline cracks are checked at the weld points.
Also, the condition of the shoes and their pads is visited. If the shoe pad is worn out, the carring metal will contact the rail and cause failure. Paying attention to these things during the operation period is a supplement to important points of installing carsing in Pars Shiraz lifting industry. We advise our customers to have a valid service and maintenance contract to ensure the health of this vital part.
