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.
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.
