húzótoló

Húzótoló is a device designed to apply a controlled tensile (pulling) force to a sample, component, or workpiece. In Hungarian technical usage the term covers various instruments used to generate and measure pulling load, and is often translated as "pulling device" or "tensioner."

A typical húzótoló consists of a rigid frame or gantry, clamps or jaws to grip the test piece, a drive mechanism (manual crank, electric motor, or hydraulic/pneumatic actuator), and a force-measuring element such as a load cell or dynamometer. Some models incorporate displacement sensing, control electronics, and data logging. Operation generally involves securing the specimen, selecting a target force or elongation, and initiating the drive while recording force and displacement.

Common applications include material testing (fibers, textiles, polymers, metals) to determine strength, elongation and stiffness; quality control in manufacturing; and laboratory research. Field uses include pulling cables or hoses through conduits, installing lines, or testing ropes and wires. The term may also describe portable tensioning devices used to apply draw to a line or cable during installation.

There are several variants, including laboratory universal testing machines and portable field tensioners. Such devices are typically designed to meet applicable standards for force measurement and safety, and require regular calibration to ensure accuracy.

Note: The exact meaning of húzótoló can vary by industry; in some contexts it may be referred to by more specific names such as tensioner or pulling rig.
