Ice Resurfacer Knife in Beijing 2022 Olympics

From the fulfillment of the centennial Olympic dream in 2008 to the reunion with the Olympic Movement in 2022, Beijing has become the first "City of Double Olympics" in history.

China overcame the impact of the epidemic and made great efforts to hold a simple, safe and wonderful Winter Olympic Games, with first-class competition venues and excellent organization and services, which won wide acclaim from the Olympic family and the international community.

Speaking of arena facilities, have you ever wondered why the ice surface of the ice rink is so flat and smooth? Let me introduce an amazing machine to you, the ice resurfacer. Now let's go back to 1940 to see how an ice resurfacer was created.

In order to have a better understanding of ice resurfacing blades, we have to know what is an ice resurfacer first. Now let's go back to 1940 to see how an ice resurfacer was created.

1940, that was when Frank J. Zamboni, his brother Lawrence and a cousin built and opened an ice rink in Paramount, Calif. But when it came to maintenance, the 20,000-square-foot rink sounded like a nightmare. To resurface the ice, they used a tractor with a blade to scrape the top layer. A crew of people scrambled behind to collect ice shavings and spray the surface with hot water. After waiting for the water to refreeze, the process took a whopping hour and a half, which must've been a considerable chunk of time to usher skaters off the ice.

Frank Zamboni struggled with how to keep the ice clean and kempt, and spent the next nine years building a contraption that would let skaters glide prettily. (Or fall smoothly, depending on your skill level.) He spent some serious time creating an almost frightening fusion of a machine. This thing had a Jeep engine, the chassis of an oil derrick and the hydraulic cylinder of a plane among other things. But it worked, and the Model A Zamboni Ice Resurfacer finally did the job right in 1949.

Now let's get down to business. How the heck do these massive machines that look like the boxy cousins of a tractor actually do their job?

1) SHAVING

A 57-pound, 70-inch steel blade sharp enough to slice through a stack of newspapers peels the top one-sixteenth of an inch, often less, from the scarred surface of the ice. 

2) COLLECTING

A horizontal screw inside the conditioner (the hooded assembly below the driver’s seat) collects the shavings, feeding them to a vertical screw which lifts them to the slinger—a rotating paddle that tosses the shavings into the snow tank at the front of the machine.

3) WASHING

Clean water is fed from the wash tank in front of the driver down to the conditioner. The water is sprayed on the ice in front of a squeegee that collects the water and picks up dirt and other debris, such as tossed coins or broken teeth. These are filtered out before the water is returned to the wash tank for re-use.

4) RESURFACING

Clean water from a heated tank is spread on the ice by a heavy cloth applicator. Water temperature is critical to ice quality, with 140 degrees a common benchmark. Coils beneath the ice refreeze the surface. Hockey players and speed skaters want harder ice while figure skaters prefer softer ice to help them dig in their edges on landing.

Resurfacing blades is used in the first and most important step, shaving.
