Construction screw jacks are mechanical devices used to lift, lower, position, and support heavy loads in various construction applications. They operate through a screw mechanism, providing precise control and high load capacity. These jacks are essential in industries such as building construction, infrastructure projects, and industrial maintenance, offering reliability and safety in demanding environments. Their design allows for vertical or horizontal operation, making them versatile tools for professionals.
Our construction screw jacks are engineered with advanced features to ensure optimal performance:
Below is a detailed table outlining the specifications for our range of construction screw jacks. This information helps in selecting the right jack for your project needs.
| Model | Load Capacity (tons) | Lift Height (mm) | Screw Diameter (mm) | Weight (kg) | Operation Type |
|---|---|---|---|---|---|
| CSJ-101 | 5 | 300 | 30 | 8 | Manual |
| CSJ-202 | 10 | 400 | 40 | 15 | Manual |
| CSJ-303 | 20 | 500 | 50 | 25 | Hydraulic-Assist |
| CSJ-404 | 50 | 600 | 60 | 40 | Electric |
| CSJ-505 | 100 | 800 | 80 | 70 | Electric |
Additional parameters include thread pitch (e.g., 5 mm per revolution for precise adjustments), temperature resistance (operating range from -20°C to 80°C), and safety factors (designed with a 2:1 safety ratio to handle unexpected overloads).
Construction screw jacks are utilized in a wide array of scenarios:
Their adaptability makes them indispensable in both temporary and permanent installations.
What is the maximum load a construction screw jack can handle?
Our jacks range from 1 to 100 tons, with custom models available for higher capacities. Always refer to the product specifications and do not exceed the rated load to ensure safety.
How do I maintain a construction screw jack?
Regular maintenance includes cleaning the screw threads, applying lubricant as recommended (e.g., grease or oil), inspecting for wear or damage, and storing in a dry environment. For electric models, check electrical components periodically.
Can construction screw jacks be used in outdoor conditions?
Yes, many models are designed with weather-resistant coatings and materials to withstand outdoor environments. However, avoid prolonged exposure to extreme moisture or corrosive substances without proper protection.
What safety precautions should I take when using a construction screw jack?
Always use on a stable, level surface; employ safety locks or secondary supports for critical lifts; never exceed the load capacity; and ensure operators are trained in proper usage. Regular inspections are crucial to prevent failures.
Are there electric or hydraulic options available?
Yes, we offer manual, hydraulic-assist, and fully electric construction screw jacks. Electric models provide faster operation and remote control capabilities, ideal for repetitive tasks.
How do I choose the right construction screw jack for my project?
Consider factors such as load weight, required lift height, operating environment, and frequency of use. Consult our specifications table and, if needed, contact our technical support for personalized recommendations.
What is the lifespan of a construction screw jack?
With proper maintenance, our jacks can last for decades. Lifespan depends on usage intensity, environmental conditions, and adherence to maintenance schedules. Heavy-duty models are built for long-term reliability.
Can multiple construction screw jacks be used simultaneously?
Yes, for lifting large or uneven loads, multiple jacks can be synchronized using alignment systems or control units to ensure even distribution and prevent tipping. Always follow manufacturer guidelines for group operations.
