Generally, industrial heavy equipment such as a forklift, excavator, etc. has a counter weight acting as a balancing load to counterbalance the weight of the machine or the moment due to the load, which acts to balance the external force acting on the machine.

Such a counterweight is generally manufactured by a method of manufacturing all of the castings using the casting, but there is a problem that the material cost is excessively generated when the counterweight is manufactured.

Recently, in addition to the counterweight for making the entire casting, a method of filling a weight adjusting material made of iron pieces, concrete, heavy concrete, scrap iron, etc. until the weight of the weight adjusting material is used is used. However, And workability is low. As a result of pollution of the working environment and filling of heavy materials such as steel pieces due to dust generation, worker's musculoskeletal diseases frequently occur and are recognized as a repelling process.

Recently, in addition to the counterweight for making the entire casting, a method of filling a weight adjusting material made of iron pieces, concrete, heavy concrete, scrap iron, etc. until the weight of the weight adjusting material is used is used. However, The workability is low, and the work environment is contaminated due to the generation of dust, resulting in frequent occurrence of musculoskeletal diseases of workers.

The weight concrete filled in the inside of the counterweight is made of concrete having a larger unit volume by using heavy aggregate having a larger specific gravity than that of the aggregate used in ordinary concrete.

In order to solve such a problem, a method of manufacturing a counterweight is disclosed in Korean Patent Laid-Open Publication No. 10-2011-0013412.

Conventional heavy concrete contains fine aggregate, and the fine aggregate has a particle size of less than 0.15 mm and an aggregate of 2.5 mm or more and less than 5 mm.

The above-mentioned counterweight filler consumes a large amount of concrete, and a large amount of material cost is generated. In the manufacturing work, dust is generated in a lot of work sites, which can cause harm to the health of the worker.

A feeding conveyor 18 is provided below the feeding hopper 16 and a mixing material falling on the lower portion of the feeding hopper 16 is seated on the upper surface of the feeding conveyor 18, (S120) of conveying the mixed material in one direction;
A mixing sensor provided at an end of the conveying conveyor 18 for storing a mixing material supplied along the conveying conveyor 18 inside the feed hopper 40 and a weight sensor (S30) of detecting the weight of the mixing material by sensing the weight of the supply hopper (40) and controlling the amount of each of the mixing materials in accordance with the input amount information of the control unit (50);
The blocking plate 44 is opened when the supply amount of the mixing material stored in each of the supply hoppers 40 coincides with the input amount information transmitted from the control unit and the supply conveyor 60 A mixing material supplying step S140 for moving the mixing material to the mixing drum 70 side;
The mixing material moved along the feed conveyor 60 is stored in the cylinder in the cylinder of the mixing cylinder 72 and the cement supply hopper 62 is opened so that an appropriate amount of cement and water are mixed with the mixer, A mixing material stirring step S150 in which the mixing material, cement and water stored therein are stirred by rotating the mixing cylinder 72 by rotating the mixing cylinder 72 by operating the rotary motor 74, ;
The stirring drum 80 and the driving wheel 84 are installed under the mixing drum 70 to transfer the stirring drum 70 to the side of the counterweight casing C, The mixing guide is placed in the inlet of the counterweight housing (C), the end of the supply guide (76) installed on one side is placed in the inlet of the counterweight housing (C) Solidification step (S160); Wherein the weight of the counterweight is in the range of.
