**1. Product Overview**
**The Lifting
Hydraulic Cylinder is a
Hydraulic Actuator designed specifically for vertical lifting scenarios. It uses hydraulic oil to drive the piston rod to extend, achieving smooth lifting, positioning, and holding of heavy objects. Widely used in logistics handling, automobile maintenance, industrial production lines, and high-altitude operation equipment.
**2. Core Features**
✅ ** Large tonnage lifting - with a carrying capacity ranging from 1 ton to 500 tons (such as heavy-duty gantry cranes).
✅ ** Self locking anti fall * * - Integrated mechanical locking or hydraulic pressure maintaining valve, automatically locking position in case of power failure/oil leakage.
✅ ** Compact structure * * - multi-stage telescopic design (3-6 levels), low installation height, high lifting height.
✅ ** Stable Control * * - Buffer Design+Throttle Valve Adjustment to Avoid Shock and Shake during Start/Stop.
✅ ** Durable protection * * - chrome plated piston rod+dust cover, suitable for factory dust and humid environments.

-Calculate the total lifting weight (including the platform's own weight).
-Determine the minimum contraction height and maximum extension height requirements.
2. * * Installation method * *:
-* * Flange fixed * *: Heavy equipment (such as gantry cranes).
-* * Earring hinged * *: Scenes that require swinging adjustment (such as dump trucks).
3. * * Safety Requirements * *:
-Choose models with * * mechanical locking * * (threaded lock/pin lock) or * * hydraulic lock * *.
4. * * Environmental adaptation * *:
-Select * * low-temperature sealing components * * (-40 ℃ fluororubber) for low-temperature environments.
-Choose * * stainless steel cylinder or * * surface coating * * for corrosive environments.
