Picking Up Heavy Object sIt is important to understand how to lift objects correctly. The results of improper handling of materials may result in a painful hernia, a strained or pulled muscle, or a disk lesion. The following rules are to be observed when lifting heavy objects. 1. Do NOT lift an object if it is too heavy or too bulky for good balance.
Get help or use mechanical aids such as a dolly or hand truck. 2. Keep the load as close to the centre of your body. The farther the load is from the small of your back, the greater the strain. That is the reason a heavy compact load is easier to lift than a bulky, lighter load – you just cannot get the bulky object close to you.
The best way to handle a compact load is to squat down close to the load with one foot alongside it and the other foot behind it. With the feet comfortably spread, you will have better stability with the rear foot in the position for the upward thrust of the lift. 3. Pull the load toward you, then lift it gradually.
Avoid quick and jerky motions. Push up on your legs while keeping your back straight. A straight back keeps the spine, back muscles, and other organs of the body in the correct alignment. Tucking in your chin helps to align the spine.
No matter what size the load, get as close to it as you can; then get a good grip by using the full palm and extending your fingers and hands around the object. Remember that your fingers have very little power and need the strength of your entire hand. Keep your arms and elbows tucked into the side of your body to help keep the body weight centred. Avoid twisting your body during the lift or while moving the load; change directions by moving your feet. Twisting your body during a lift is one of the most common causes of back injury. 4.

Assignment Mechanical Principles and Concepts Related to Movement Stability The concept of stability is related to equilibrium, a state of equalized forces on the body. Stability is the ability of the body to regain equilibrium after it s has been displace. There are two types of equilibrium, static and dynamic. Static is where the center of gravity is un a stable position, like in performing a ...
Be sure to have a clear vision over the load you are handling. 5. Do NOT change your grip while you are carrying the load. 6. Face the spot in which you intend to set the object down; bend your knees keeping your back as straight as possible and the weight of the object close to your body. 7.
Always allow enough room for the load to prevent injury to your toes and fingers. 8. When you are placing an object on the table or bench, set it down on the edge and push it forward with your arms and body. If the load is too heavy or too awkward for you to move alone – GET HELP! Remember: LIFT WITH YOUR LEGS, NOT YOUR BACK! a) b) a) This image shows the correct lifting method.
There is a very slim chance of injury. b) This image shows the incorrect lifting method. The man is lifting with his back and not his legs. This method has a very high chance of injury.
