Abstract

PURPOSE: To provide an adjusting apparatus for hoisting speed which ensures efficient hoisting state according to the hoisting condition with a simple construction through adjustment of the maximum hoisting load and the winding-up speed simply by changing mount point of head sheave.
CONSTITUTION: In operation, first, when a hoisting rope 5 from a hoisting drum 1 is applied with brackets 2a and 2b having sheaves 4a and 4b and brckets 13a and 13b having a sheave 3 fixed to a frame of a trolley a with bolts 11 and 14, a hook 8 is suspended by a 8-piece hanging. Here, a cargo of large load can be hoisted at a lower speed. Then, the brackets 13a and 13b are removed and tied with hanger plates 7a and 7b through a T-shaped support. Thus, a 6-piece hanging is made. If the brackets 2a and 2b are removed and tied in the same manner. Then, a 4-piece hanging is made. In this manner, through the suspension load is lowered, the hositing speed is gradually increased.
