US based Champion Hoist and Equipment takes the checkered flag with an efficient, first-to-market scissor lift designed to feature STRENX® high performance steel manufactured by SSAB. Champion’s lighter model not only delivers high yield strength to manage the heaviest loads, but also maintains structural integrity, while reducing overall gross vehicle weight by nearly a quarter ton.

For many fleet managers and commercial truck owners, gross vehicle weight determines the class that their trucks may legally operate. The heavier the truck, the higher the class and the more restrictions are applied. Champion’s customers like the North Carolina Department of Transportation benefit significantly from a lighter class for shorter hauls using less fuel, and heavier loads are easily lifted without all the extra weight.

Stronger, yet lighter scissor, helps customers lift their business

Strenx® 100 XF is a thermomechanically rolled steel made for cold forming with a minimum yield strength of 689 MPa (100 ksi), or one thousand pounds per square inch. It’s called high performance steel because it means that applications can be both stronger and lighter. Creative engineers can challenge the design envelope because it’s made to meet specific guarantees for thickness, flatness and impact properties. Champion saw that by redesigning their scissor lifts, they could create a thinner, stronger and lighter model to give customers a true advantage.

“Awhile back, our specified steel for hoists mysteriously began to fail.” explained Pat Godwin, Sr., founder of Champion’s parent company, the Godwin Group.

“While I investigated the issue, which cost me three major accounts, I uncovered inferior grades in our supply. We needed to make a change – fast. I was using a 345 MPa (50 ksi) minimum yield, but when I considered the properties of Strenx® 100 XF, I could go thinner and get a 689 MPa (100 ksi) minimum yield. I tweaked the design and we switched. My customers trust me, and in the end, two of those lost accounts came back.” Godwin said.

Redesign reduces weight and production costs

According to Ryan Taylor, CEO of the Godwin Group, the original hoist’s design footprint was already extremely tight. With that all-important tweak on the schematics maximizing the bendability of Strenx® 100 XF, Pat was able to flatten the main assembly and modify the scissor in a way that did not affect the fuel tank cavity or impact a critical triangular lifting equation. Some of the bracings also lost weight as shown in the comparison photos “before” and “after” the weight-loss. Not only did double-boxed wall assemblies go by the wayside, but the new design also reduced production costs.

Making friends in the workshop and with customers

“When we introduced Strenx® 100 XF to the shop, we cut our per-piece welding time in half, and for our team that meant more money in their pockets because our compensation structure is based on the number of pieces completed versus straight hourly production,” Taylor said. “Our press-brake operators also picked up the change seamlessly, and we didn’t need to recreate or modify our patterns, which was another huge efficiency gain on the production line. When we reduce labor costs, we’re more competitive and give our customers greater value.”

SSAB EcoUpgraded report provides sustainable advantage

Using Strenx® 100 XF gives Champion’s customers a competitive edge by increasing profits, reducing fuel costs, lowering CO2 emissions, extending overall service life and making the vehicle safer by using thinner, lighter weight steel. For example, every 4-ton commercial class 4 or 5 utility truck outfitted with a Champion Hoist scissor lift saves 2.3 tons of CO2 over its lifetime. That’s equal to the carbon sequestered by 10.117m2 (2.5 acres) of US forests in one year. Plus, the company increased annual profits by €1.603 ($1,768) by making the switch.

Engineers looking to improve designs or lead their markets with innovations can calculate potential benefits with SSAB’s EcoUpgrade app. Champion’s example of going from a 345 MPa (50 ksi) to a 689 MPa (100 ksi) material equaled a total material savings of 57% and a 80kg (176 lbs.) higher capacity.
