Hydraulic hoists are suitable for various engineering scenarios, and targeted plans need to be developed to meet construction requirements in different scenarios, as follows:

1、 Construction of large bridges

Applicable scenarios: Key processes such as main cable installation and tower lifting.

Program features:

High precision control: Millimeter level positioning is achieved through hydraulic synchronous lifting technology to ensure the installation accuracy of the main cable.

Dynamic stability: The hydraulic system provides stable lifting force, reducing the impact of wind and temperature changes on construction.

Geological adaptability: For complex geological conditions such as soft soil foundations, special construction techniques and materials (such as pile foundation reinforcement) are used to ensure the stability of the foundation.

Case: A large-scale bridge project spanning a river, with a main span of 800 meters, uses hydraulic lifting technology to complete the installation of the main cable, increasing construction efficiency by 30% and reducing safety risks by 50%.

2、 Installation of high-rise buildings and industrial equipment

Applicable scenarios: Steel structure hoisting of high-rise buildings, installation of large mechanical equipment.

Program features:

Modular design: Flexible configuration of hydraulic pumps, hydraulic cylinders, and other components based on building structure or equipment weight.

Intelligent control: equipped with an intelligent control system, real-time monitoring of parameters such as pressure and flow, and automatic adjustment of lifting speed.

Safety redundancy: Install dual braking devices (such as solenoid valves and mechanical brakes) to ensure quick shutdown in emergency situations.

Case: A high-rise building steel structure hoisting project used hydraulic lifting technology to lift steel components weighing 500 tons to a height of 200 meters, reducing the construction period by 20%.

3、 Construction in special environments (nuclear power plants, chemical plants)

Applicable scenarios: Equipment maintenance and installation in high-risk environments.

Program features:

Explosion proof design: Hydraulic components are made of explosion-proof materials, and electrical components such as solenoid valves comply with explosion-proof standards.

Remote control: Reduce personnel on-site operations and minimize radiation or chemical exposure risks through wireless remote control or automated control systems.

Sealing enhancement: The hydraulic pipeline adopts special sealing technology to prevent the leakage of toxic and harmful substances.

Case: A nuclear power plant reactor pressure vessel maintenance project used hydraulic lifting technology to remotely replace components, reducing the operation time from 72 hours to 24 hours and reducing personnel radiation dose by 80%.

4、 Construction of large-span corridor

Applicable scenario: Overall lifting of high-altitude large-span steel structure corridors.

Program features:

Synchronous sliding technology: Combining hydraulic lifting and horizontal sliding to achieve segmented overall installation of the corridor.

Temporary facility optimization: Utilize permanent structures such as steel cow legs and steel columns to set up lifting platforms and reduce the amount of temporary support needed.

Attitude adjustment: Adjust the levelness of the corridor in the air through jog control to ensure docking accuracy.

Case: A six story steel corridor project adopts hydraulic synchronous lifting+sliding technology, which shortens the installation time of a single layer from 7 days to 2 days and reduces costs by 35%.

5、 Key points of universal construction plan

System selection:

Select high flow and high pressure hydraulic pumps based on lifting weight and height (such as bridge engineering requiring a pressure of over 20MPa).

Prioritize the use of well-known hydraulic components such as Rexroth and Parker Hannifin to ensure system reliability.

Safety design:

Configure devices such as over roll protection, overspeed protection, emergency braking, etc., in compliance with relevant standards such as the Coal Mine Safety Regulations.

Regularly conduct secondary braking tests to verify the reliability of braking performance.

Maintenance and upkeep:

Hydraulic oil is filtered every six months and replaced with new oil every year to prevent system failure caused by oil deterioration.

Electromagnetic valves, filters, and other components should be cleaned every six months to ensure flexible switching and no blockages.

Operating standards:

Drivers must hold a certificate and operate strictly according to signals. Overloading is strictly prohibited.

Closely monitor pressure gauges, thermometers, and other instruments during operation, and immediately stop for inspection if any abnormalities are found.
