Hydraulic Press for Bridge Repair

Hydraulic presses are versatile tools that can be employed in a range of applications. They boast several advantages over mechanical presses, such as ease of use and lower maintenance costs.

A hydraulic press is powered by a pump that creates pressure inside the pressing cylinder. This pressure pushes against material at an incredible rate of tons.

Why Hydraulic Presses?

Hydraulic presses are widely used in various industries for fabrication, assembly and maintenance tasks. They use pressure generated by a pump to push a steel cylinder into material at an established force.

A hydraulic press can shape, flatten, pull, lift and pierce materials to desired positions. Its versatility makes it suitable for a range of tasks from crushing car bodies to pressing picture frame trim.

Hydraulic presses have another use in waste disposal. They can be employed to crush used oil filters and squeeze out any remaining traces of oil for recycling purposes.

Hydraulic presses are often employed to assess the tensile strength and behavior of set concrete. These tests provide data related to predefined tension softening, which manufacturers use to adjust their formulas accordingly.

Straightening of Electro Welded Structures

Hydraulic presses are often employed for straightening electro welded structures and flame cut sheets.

They feature a moving frame and cylindrical piston which allow access to all pressing and straightening points on the workpiece. This is accomplished through lateral displacement of the piston and longitudinal movement of the bridge, motorised by frequency inverter and cogged belt.

These hydraulic cambering presses from RHTC in the Netherlands are built for heavy-duty use and manufactured from S355JR steel. Suitable for straightening, bending and machining large profiles and beams, their horizontal structure is stable and robust with a large supporting back table with 'T' grooves as well as a pushing main table featuring four cylindrical lateral guides.

Straightening of Flame Cut Sheets

Flame straightening is a relatively recent method for repairing damaged steel bridges. It involves applying controlled temperatures and cooling in order to cause contraction or localized shrinking within the target material.

This process is similar to reverse welding or fusing, but with much more controlled heat application and minimal risk of material damage. Therefore, it can be used on most steels and to correct a variety of structural flaws.

Hydraulic presses are one of the most efficient tools for this job, particularly when motorized models are employed. For straightening electro welded structures and flame cut sheets, the TL-400/6000-E is specifically designed with a slide frame and moveable headstock in one machine. It boasts high power frequency inverter technology as well as an electric cylinder featuring lapping liner, chrome plunger, and maintenance-free anti wear guides.

Straightening of Steel Beams

A hydraulic press is a large-scale tool used to shape metal workpieces. It consists of the mainframe, pump, cylinders and bolsters which work together to generate consistent pressure measured in tons.

This hydraulic press is ideal for a variety of jobs, such as straightening steel beams. It features a double acting cylinder, chrome plunger and limit switches to regulate cylinder stroke length.

This machine also comes equipped with a pressure regulator and gauge in tons, for quick and effortless manual operation.

Hydraulic presses are user-friendly and cost-effective to run, making them a great option for many shops. However, they must be serviced regularly and equipped with safety devices - this could be an economical way to safeguard your workers' safety.
