In many situations it would be highly advantageous to be able to use human muscle power to carry out much heavier work, for example lifting, than is currently possible. According to the invention, this is done ergonomically correctly by means of the user's body weight and muscle power cooperating to give a combined force, by means of the fact that a foot support 1 is connected to a handle 2 in such a way that the foot support moves downwards when the handle is lifted, and vice versa. <IMAGE> |
