Mandrel Benders

Strong range of profile bending machines

A look at the PBT AG product range reveals a series of machines of varying complexity for bending tubes and profiles. These are suitable for use with all common materials - steel, aluminum and copper. The variation basically ranges from compact, relatively mobile, standard machines to complex special machines according to customer requirements for maximum performance demand. PBT also offers both manual control and software-controlled operation:

- Tube bending machine ARKUS12, 540 kg weight:

The smallest machine of the company, the ARKUS12, has a pressure capacity of 12 tons and is designed for profiles with an edge length of 110 mm as standard. Optionally, rollers with 220 mm can also be used. From 256 mm (optionally 80 mm) and up to 518 mm, the front rollers can be continuously spaced so that, with an additional bending attachment, the smallest radii of up to R35 mm can be achieved. As the most compact and correspondingly lightest variant, the ARKUS12 can be moved by means of a lift truck.

- Tube bending machine BENDO, 1050 kg weight:

With almost twice the weight of the ARKUS12, the BENDO also achieves almost twice the output. The machine makes it possible to bend pipes with a pressure capacity of up to 20 tons. The standard rollers are for edge lengths up to 200 mm and a distance between the front rollers from 280 mm for also very small radii when bending. The shaft diameter of the rollers is 65 mm. Transport is also possible here with the help of a lift truck.

- Tube bending machine PBT25, 1150 kg weight:

With 27 tons of pressure power, the PBT25 is the strongest tube bending machine without servo drive. Corresponding to this power, the 300 mm high rollers are also made for profiles with 105 mm roller diameter, while the distance between the front rollers is even only 200 mm. Smallest bending radii with large profiles can thus be realised. Thus, the PBT25 combines flexibility and highest performance. Despite this variety of applications and the enormous weight, the machine can still be moved with a lift truck.

- PBT35 Servo tube bending machine, 2250 kg weight:

With the PBT35, the company introduced the first tube bending machine with full servo drive at the time. This technology is still considered absolutely innovative. With this drive, the machine achieves a pressure capacity of 35 tons, while 70% of energy is saved and the oil volume is low at 9 litres. At the same time, the 400 mm high rollers with a minimum distance of 360 mm on the Y-axis still allow a small bending radius even with a roller diameter of 105 mm. However, transporting the machine requires a forklift or a crane due to its heavy weight.

- Tube bending machine HELIX Servo, 5500 kg weight:

With the HELIX Servo, PBT AG offers its premium model. The machine with integral servo drive generates a full 65 tons of pressure and enables the bending of profiles with a diameter of up to 500 mm. The front roller distance is at least 630 mm. According to these values, the HELIX Servo is used especially for large workpieces up to beam constructions. Nevertheless, an oil volume of 9 litres and 70% energy savings thanks to the drive also apply here. However, only a crane comes into question for the placement of the machine.

Request an overview without obligation

There are many considerations that will go into the selection of a PBT profile bending machine, hydraulic or servo drive, control system and mandrel bending machine extension. Please reach out to the experts and technicians at Boschert USA and PBT to get their perspective and to craft a solution that meets the needs of current and future projects. Virtual demonstrations are available as well. Inquiries will result in customer-oriented communication from planning to commissioning and subsequent regular maintenance. In this way, PBT's advantages will continue to apply to every bending process in the future: exact precision, consistent reliability and maximum performance thanks to modern technology.
