Some of the measuring systems included in this bench are computerized systems, laser systems, and mechanical systems.
• Bench without measuring systems: This is a traditional auto body straightening bench that lacks measuring systems. As a result, technicians have to rely on manual measurements and assessments when working on a vehicle's body. The lack of measuring systems makes these benches more affordable, but they may require more time and effort to ensure precise alignment and measurements.
• Portable benches: These are designed to be moved from one place to another. They are smaller and lighter, making them suitable for small workshops or on-site repairs. Despite their portability, they are equipped with essential features such as clamps and pulling mechanisms to handle frame straightening tasks.
• Bench with hydraulic systems: The straightening benches have hydraulic systems that generate a high and controlled force for pulling and pushing damaged areas of a vehicle's frame. The benches are suitable for working on heavily damaged vehicles since the hydraulic system offers more power and precision during the straightening process.
• Universal benches: These are designed to accommodate a wide range of vehicle sizes and types. They have adjustable features, such as movable towers and adaptable holding systems, to cater to different vehicles' dimensions and configurations. Universal benches are suitable for workshops that handle various vehicle models and minimize the need for multiple specialized tools.

Specifications and maintenance of auto straightening benches

Specifications of auto straightening benches

Auto straightening benches have different specifications that suit various vehicle sizes, types, and construction methods. Below are some general specifications to expect.

• Capacity

  The straightening benches have a specified working load capacity. The working load capacity is the maximum weight they can handle. For instance, a bench with a capacity of 5000 pounds can handle vehicles weighing up to 5000 pounds. The benches also have a lifting capacity, which is the maximum weight they can lift. The lifting capacity is always higher than the working load capacity.

• Length and Width

  The benches have different lengths and widths, which affect their working space. Typically, an auto straightening bench has a length of 15 feet to 25 feet. The width is usually 5 feet to 8 feet. The length provides a larger working area, so users can work on large vehicles without restrictions.

• Height Adjustment

  The auto straightening benches have different height adjustments that accommodate different technicians' working preferences. A straightening bench with an adjustable height can move up to 40 inches above the floor. The height adjustment makes the bench suitable for various collision repair tasks.

• Pulling Force

  The pulling force is the maximum force the bench can exert when pulling or pushing a vehicle. The pulling force is measured in pounds or Newtons. Most auto straightening benches have a pulling force ranging from 2000 pounds to 15000 pounds. The force ensures that the technicians can effectively straighten the most challenging frames.

• Alignment Accuracy

  The alignment accuracy is the degree of precision the bench can achieve when aligning the vehicle's components. The alignment accuracy is measured in millimeters or inches. An auto straightening bench has an alignment accuracy of ±1mm, making it possible to perform accurate alignment tasks.

Maintenance of auto straightening benches

Maintaining the auto straightening bench is very important. Proper maintenance of the bench ensures that it operates optimally, improving safety and precision when repairing vehicles. Below are some maintenance tips.
