Generally, there are 3 kinds
drive for surgical table:
1. Hydraulic transmission
means that the oil is injected into the tubing from the tank through an oil
pump, solenoid valve controls the opening and closing of the oil circuit, using
hydraulic pressure to push the piston in the hydraulic cylinder to achieve
various positions of the operating table.

transmission schematic diagram)
2. Mechanical transmission
means sending signals to the motor through the control circuit, the motor
drives the transmission components such as the turbine, the worm, the gear, and
the rack, thereby realizing various actions of the operating table.

3. The pneumatic part is
mainly driven by a self-locking gas spring. The self-locking gas spring has a
needle valve at the end of the piston rod. When the needle valve is opened, the
self-locking gas spring can be freely adjusted to achieve various positions of
the operating table, when the needle valve is released, the self-locking type
gas spring can be locked in position at the moment, and the self-locking force
is large, and the support can be achieved.
