Cylinder
Hydraulic system arm. Cylinders transfer the force to the car.
There are several items determining cylinder movement quality. Cylinder design, raw material quality, rod straightness, rod surface roughness, rod roundness, sealing elements, machining parts, welding, assembling, packaging ….
Using high quality raw material like Belarus rods, H8 inside honed or roller burnished tubes, German Freudenberg seals besides quality control procedures and final vertical dynamic test over the test bridge let us produce high quality products.
Indirect cylinder
1:2 systems
One pully is installed over the cylinder and a set of ropes transfer the cylinder movement to the car. In this case cylinder movement is doubled that’s why it is called 1:2 system
1:3 systems
One pully is installed under the cylinder in addition to the over one in 1:2 system and a set of ropes transfer the cylinder movement to the car. In this case cylinder movement is tripled that’s why it is called 1:3 system
Direct Cylinders
Direct Under
Cylinder head is directly connected to the car, so 1 meter extension od cylinder move the car 1 meter up.
Direct center single stage cylinder
These cylinders are used in areas which digging the hole in the ground is possible. Depth of this hole depends on car travel. For example, if the travel is 6 meters, we need a hole with 6 meters depth from bottom of the pit. It is recommended to use these cylinders for car travel of maximum 6.5 meters.
Simplicity is accompanied with security in these systems. Cylinder design lets the serviceman to replace the sealing kit only by opening 8 screws.
(In Behyad every single cylinder is dynamically tested thanks to 18 meters test tower. So, the cylinder is inspected in different aspects like; weld lines, movement smoothness and continuity, head leakage.)
In order to support the cylinder against corrosion and extend its lifetime, isolating the hole against humidity is very important.
Direct center 2 stage synchronized cylinder
These cylinders are used in areas which digging the hole in the ground is possible. Depth of this hole depends on car travel. For example, if the travel is 10 meters, we need a hole with 5 meters depth from bottom of the pit. It is recommended to use these cylinders for car travel of maximum 12 meters.
Contrary to Industrial telescopic cylinders, in these synchronized telescopic cylinders 2 rods extends simultaneously. It means if the first rod extends one meter, second rod also extends one meter. This will lead to a smooth travel experience for the car passenger.

Direct center 3 stage synchronized cylinder
These cylinders are used in areas which digging the hole in the ground is possible. Depth of this hole depends on car travel. For example, if the travel is 15 meters, we need a hole with 5 meters depth from bottom of the pit. It is recommended to use these cylinders for car travel of maximum 18 meters.
Contrary to Industrial telescopic cylinders, in these synchronized telescopic cylinders 3 rods extends simultaneously. It means if the first rod extends one meter, second and third rods also extends one meter. This will lead to a smooth travel experience for the car passenger.

Direct center 4 stage synchronized cylinder
These cylinders are used in areas which digging the hole in the ground is possible. Depth of this hole depends on car travel. For example, if the travel is 20 meters, we need a hole with 5 meters depth from bottom of the pit. It is recommended to use these cylinders for car travel of maximum 22 meters.
Contrary to Industrial telescopic cylinders, in these synchronized telescopic cylinders 4 rods extends simultaneously. It means if the first rod extends one meter, second, third and fourth rods also extends one meter. This will lead to a smooth travel experience for the car passenger.

Direct side single stage cylinder
These cylinders are used in projects which has a deep pit and /or long overhead.
Simplicity is accompanied with security in these systems. Cylinder design lets the serviceman to replace the sealing kit only by opening 8 screws.

Direct side 2 stage synchronized cylinder
These cylinders are used in projects which has a shallow pit and /or short overhead.
It is recommended to use these cylinders for car travel of maximum 12 meters
Contrary to Industrial telescopic cylinders, in these synchronized telescopic cylinders 2 rods extends simultaneously. It means if the first rod extends one meter, second rod also extends one meter. This will lead to a smooth travel experience for the car passenger.

Direct side 3 stage synchronized cylinder
These cylinders are used in projects which has a shallow pit and /or short overhead but car travel is long.
It is recommended to use these cylinders for car travel of maximum 18 meters
