release arm 42 of the brake unit 14 will pivot downwardly resulting in the cam 40 coming into contact with the hoisting rope a the friction between the braking surface 41 of the cam 40 and the hoisting rope a is sufficient so as to block movement of the rope a at the brake system 10 and thus support the load if the user decides to pull the hoisting rope a once more the brake unit 14 will simply pivot to the hoisting position of fig5 by the hoisting rope a reaching the tautened state thereby releasing the brake system 10 and allowing movement of the hoisting rope a the clearance between the braking surface 41 and the hoisting rope a may be large enough that the brake system 10 remains in the hoisting position of fig5 despite the hoisting rope a being semi taut not fully taut as in fig5 not loose as in fig6 this feature is quite practical as a variation of tension in the hoisting rope a will impact the speed at which the load is lowered it is therefore observed that the brake system 10 does not require any other manipulation in lowering a load other than the releasing action of the user on the hoisting rope a the brake system 10 therefore adapts to the logic of movements of the hoisting rope a thereby simplifying the manipulations required to brake movement.
