Our Bones Are Literally Stronger Than Steel

The science behind the Liftsmart is revolutionary. It proves we have engineered a device that plays to our strengths while simultaneously avoiding points of weakness in the human body.

A cubic inch of bone can bear a load of over 8,626 Kgs — roughly the weight of five standard pickup trucks. Bone is about four times as strong as concrete.

So, if the human skeleton can withstand such tremendous force, why do we frequently injure ourselves lifting loads of only 16kgs+ at work and around the house? Why is repetitive lifting so damaging and the irrefutable cause of injuries like repetitive strain injury (RSI), occupational overuse syndrome (OOS), cumulative trauma disorder (CTD) and work-related musculoskeletal disorder (WRMSD)?

Simply put, it’s our muscles that let us down. Muscles fatigue easily. They run out of oxygen, fill up with acid, and strain from overuse. Tendons and ligaments sprain, strain and tear. Liftsmart uses physics to overcome the limits of biology. Liftsmart shifts the weight of the load onto your hips, to leverage the strength of your skeleton, and stronger muscles like your legs. At the same time it reduces the force applied to the pivot points throughout your body.

The design of the harness ensures the load is carried closer to the body and towards your centre of gravity. This is where we are naturally the strongest. Liftsmart forces its user to adopt correct posture and lift with the knees, legs and hips. The back brace raises the weight to the shoulders and upper back, to avoid the injury prone lower back.

The design prevents over-exertion, hyperextension and over-rotation.

Don't take our word for it

A study done at the University of Auckland proved that Liftsmart significantly reduced peak elbow torque. Without the device, peak elbow torque was between 36,000 and 38,000 N.mm (Newtons per millimetre). With the belt only 4,500 N.mm were exerted on the elbow. A similar study by Hong Kong University tested subjects as they carried loads of various weights on a treadmill wearing a similar belt device. The study found that ‘At a load of 15kg, the mean heart rate, normalized oxygen uptake, minute ventilation, and peripheral rating of perceived exertion were significantly lower by 6.6, 8.0, 11.8 and 13.9% respectively. The device significantly improved posture and reduced pressure on the body. What a winning combination.

Workplace Health
and Safety

All the workplace health and safety science conducted in the last hundred years unanimously agrees that manually lifting loads is dangerous. The repetitive nature of all labour-intensive jobs fatigues muscles and significantly increases the chance of injury. A number of conditions have been linked to these practices including RSI, OOS, CTD and WRMSD.

Liftsmart has the potential to become an indispensable industry standard in workplaces. It makes work safer by reducing the strain on the user while carrying loads. What’s more, Liftsmart frees up the hands to interact with the environment, which has irrefutable safety benefits.

Maintain contact with handrails while carrying loads up and down stairs, open doors without precariously balancing loads on your knee, and safely use ladders while maintaining three points of contact. Liftsmart has the potential to revolutionise workplaces by making the single person carrying of objects far easier and safer.
