Product Description

Chain Type Simple Hydraulic Jack

The LYT-type hoist is composed of a one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain, and oil way. The moveable pulley is designed to enlarge the chain stroke, making the traveling distance of the cylinder 1/2 of the lifting distance of the chain. This system is specifically designed for inverted installation and construction of various large storage tanks.

Standard models include LYT-120-2700, LYT-200-2700, and LYT-300-2700. Customized strokes are available upon request.

Operation Principles

The system utilizes an inverted method for tank construction:

Lifts the tank roof and the first layer of siding initially.
The hydraulic jack pushes the movable pulley upward via the piston, driving the chain to lift the expansion ring.
Lifting height is carefully managed to allow for the next layer of plating and butt welding.
Synchronizing valves and hydraulic locks ensure the entire process is stable and safe, preventing accidental slips.

Key Advantages

Safety & Stability: Unified hydraulic control prevents sliding or falling even during power failures.
Precision Quality: Accurate lifting height control ensures perfect welding alignment for the storage tank.
High Efficiency: Simple operation reduces construction periods and labor costs significantly.
Universal Adaptability: Scalable for tanks ranging from thousands to tens of thousands of cubic meters.

Frequently Asked Questions

Q1: How many hydraulic jacks are needed for a specific project? The number of hydraulic jacks is calculated based on the total weight and diameter of the tank to ensure balanced and safe lifting.

Q2: What safety mechanisms are in place during lifting? Each hoist is equipped with a double-direction oil-way hydraulic lock to prevent the tank from falling in case of power or pressure failure.

Q3: Can the system be used for different tank volumes? Yes, the equipment is highly adaptable. By adding or decreasing the number of hoists, it can handle tanks from 1,000 to over 10,000 cubic meters.

Q4: Does the hoist require specific site conditions? The equipment is designed to be placed inside the tank during operation, making it suitable for compact construction environments.

Q5: What technical documentation is provided? We provide comprehensive technical documents, procedures, and advice to support construction planning and execution.

Q6: Is on-site training available for operators? Yes, professional training and operation services can be provided to ensure safe and efficient use of the hydraulic jacking system.
