Description

Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to a reinforced heavy-duty tensioner. Background Art

[0002] A tensioner is a device used to secure and stabilize cargo, offering safety, reliability, and ease of operation. It's primarily used during the transportation, movement, shipment, or storage of cargo. By tightening and securing cargo, they prevent it from shifting or falling during transport, ensuring safe transportation. The main types of tensioners include portable tensioners and pneumatic strap tensioners. Portable tensioners typically consist of a tensioner body and a tightening handle, equipped with a cutoff device. They're easy to operate and effectively prevent the strapping from coming apart during the tensioning process. Pneumatic strap tensioners are suitable for packaging heavy items. They provide high tightening force through pneumatic tensioning and are suitable for strapping of varying widths.

[0003] However, the existing tensioners still have certain shortcomings when used. When bundling and reinforcing heavy equipment, tensioners are generally used for fixation. However, when fixing the strap shaft, the existing tensioners generally use auxiliary tools to tighten the strap shaft to achieve fixation. Although the fixing effect is good, this fixing method is very inconvenient to operate and cannot be quickly fixed. In addition, the lock of the tensioner is generally a semi-open design, but it is easy to loosen or even slip during transportation, which creates certain safety hazards in the transportation of heavy equipment.
