Giga Olympic barbell 2.2metre 500kg carry
An Olympic barbell is a specialized type of weightlifting bar used primarily
in the sport of Olympic weightlifting, as well as in powerlifting, CrossFit,
and general strength training. It is designed to meet the specifications set by
the International Weightlifting Federation (IWF) for use in Olympic
competitions.
Here are some typical characteristics of an Olympic barbell:
1. Length:
Olympic barbells are typically 7 feet long (about 2.2 meters), although shorter
variations such as 6 feet (about 1.8 meters) or training bars may also be
available.
2. Weight:
An Olympic barbell weighs 20 kilograms (44 pounds) for men's bars and 15
kilograms (33 pounds) for women's bars. There are also lighter training bars
designed for beginners or specific exercises.
3. Diameter:
The shaft of an Olympic barbell is usually 28-29 millimeters (about 1.1 inches)
in diameter for men's bars and slightly thinner, around 25 millimeters (about 1
inch), for women's bars. The sleeves, where the weight plates are loaded, are
slightly thicker to accommodate Olympic-sized weight plates.
4. Knurling:
Knurling refers to the textured pattern on the barbell that provides grip.
Olympic barbells typically have aggressive knurling in the center portion where
the lifter's hands are placed during lifts like the snatch, clean, and jerk.
The knurling on the outer portions where the hands are placed for squats and
presses may be less aggressive.
5. Sleeves:
The sleeves are the rotating ends of the barbell where weight plates are
loaded. They are designed to spin independently of the shaft to reduce stress
on the lifter's wrists during lifts like the snatch and clean. This spinning
action allows the lifter to smoothly transition the bar around their body
during these lifts.
6. Bearings
or bushings: Inside the sleeves, there are bearings or bushings that enable the
sleeves to rotate. Bearings offer a smoother and faster spin, while bushings
provide a more controlled rotation.
7. Loadable
sleeve length: The length of the sleeve where weight plates can be loaded
varies but typically ranges from 16 to 18 inches. This allows for the loading
of multiple weight plates for heavy lifts.
Overall, Olympic barbells are built to withstand heavy loads and intense
training sessions while providing the necessary characteristics for Olympic
weightlifting movements. They are a foundational piece of equipment in any
serious weightlifting or strength training program.
