By using it in places that require little movement and require repetitive work, the manufacturing cost of the crane is reduced by more than 50% compared to the conventional diesel fueled engine and the mobile bucket crane equipped with the track for movement. Not only can the engine or track be configured, there is no risk of failure due to dust or dust on the engine or track, and the electric bucket can reduce operating costs by using electricity instead of diesel fuel. It is about a crane.

일반적으로, 버켓크레인은 땅을 파거나 산업폐기물 등을 운반하는데 사용되는 건설기계로서, 포크레인이라고도 한다. 이 용어는 프랑스의 대표적 버켓 크레인 업체의 상표명이 일반명사처럼 쓰이게 되었다.In general, the bucket crane is a construction machine used for digging or transporting industrial wastes, it is also called a fork crane. The term is now used as a generic noun for a major French bucket crane company.

최초의 버켓 크레인은 미국의 토목기술자인 윌리엄 스미스 오티스가 1835년에 발명하여 1839년에 특허를 취득한 것으로서, 당시에 오티스가 발명한 것은 기찻차길이나 운하의 굴착과 굴착된 흙을 치우기 위한 증기 버켓 크레인이었으며, 그 구조는 당시에 이미 사용중이던 증기기관으로 움직이는기차 차량이나 운반차에 크레인을 설치하고 큰 삽을 달아 이 삽이 땅을 파면 들어올려 반대편에 버리거나 도르레 등을 이용하는 것이었다. 당시에 만들어진 버켓 크레인은 서부 철도공사에 사용되어 한번에 1.1㎥를 굴착할 수 있었으며 하루에 380㎥를 굴착할 수 있었다.The first bucket crane was invented in 1835 by American civil engineer William Smith Otis and patented in 1839. At that time Otis invented a steam bucket crane for digging tracks and canals and clearing excavated soil. In other words, the structure was to install a crane on a vehicle or a truck moving by a steam engine that was already in use at the time and attach a large shovel to lift the shovel when it was dug up and throw it away, or use a pulley. Bucket cranes made at that time were used for western railway construction and were able to excavate 1.1㎥ at a time and 380㎥ per day.

우리나라에서 사용되는 버켓 크레인은 1992년 건설부 중기관리법 시행령 개정에 따라 총중량 1톤 미만인것은 농업용으로, 1톤 이상의 것은 중장비로 분류하고 있으며, 그 구조는 기관, 동력전달부, 주행부, 유압장치, 붐 및 버켓 등으로 구성되어 있으며, 주로 동력전달부는 경유로 작동되는 고가의 엔진을 사용하며, 주행부는 무한궤도를 사용한다.Bucket cranes used in Korea are classified as agricultural for those with a gross weight of less than 1 ton and heavy equipment for more than 1 ton according to the amendment of the Enforcement Decree of the Mid-term Management Act of 1992. The structure is composed of engine, power transmission, driving, hydraulic system, It consists of a boom and a bucket, and the power transmission unit uses an expensive engine that is operated via a diesel engine, and the driving unit uses an endless track.

상기와 같이 종래의 이동식 버켓크레인은 경유를 연료로 하는 엔진과, 이동을 위한 궤도가 설치되어 있어 이동성이 있다는 장점은 있으나, 이는 한곳에 고정되어 반복작업을 필요로 하는 곳에서는 오히려 단점으로 작용하게 되어지며, 궤도의 장착은 크레인의 제작비용을 급격히 상승시킬 뿐만아니라, 작동연료로 경유를 사용하게 됨으로서 작동비용 또한 상당히 소요되는 문제점이 있었다.As described above, the conventional mobile bucket crane has the advantage that the engine is a diesel fuel, and the track for the movement is installed, but there is a mobility, but it is fixed in one place is to act as a disadvantage rather than needing repetitive work In addition, the mounting of the track not only raises the manufacturing cost of the crane drastically, but also uses the diesel as operating fuel, there was a problem that the operation cost is also considerably required.

또한, 작업장에서 발생하는 먼지나 분진에 의하여 고가의 엔진이나 무한궤도가 수시로 고장이 나게되며, 이를 정비할 경우, 그 정비비용이 고가이기 때문에 사용자로 하여금 상당한 부담을 느끼게 되는 문제점이 있었다.In addition, expensive engines or caterpillars often break down due to dust or dust generated in the workplace, and when the maintenance is performed, the maintenance cost is expensive, which causes the user to feel a considerable burden.

따라서 본 발명의 목적은 상기와 같은 종래의 여러 가지 문제점을 개선시키기 위하여 안출한 것으로, 흙, 산업폐기물 등의 운반하고자 하는 대상을 퍼담을 수 있게 하는 버켓(a1)과, 버켓(a1)의 원거리 작업을 가능하게 하는 붐(a2)과, 붐(a2)을 작동시키는 유압실린더(a3)로 구성된 가동부(A)와; 상부프레임(C)을 지지하며, 버켓크레인을 작업하고자 하는 곳에 고정시키는 하부포스트(B)와; 하부포스트(B)의 상부에 설치되며, 콘트롤케빈(D), 오일탱크(E), 전기모터(F) 등을 지지하는 상부프레임(C)과; 상부프레임(C)의 상단에 설치되며, 전체 버켓크레인의 작동을 콘트롤 하는 콘트롤 케빈(D)과; 유압실린더(a3)에 오일을 공급하는 유압펌프(13)가 내부에 설치된 오일탱크(E)와; 유압펌프(13)와 연결축으로 연결되어 유압펌프(13)에 유압이 발생하도록 하는 전기모터(F)와; 유압펌프(13)에서 공급되는 오일에 의해 작동되는 유압모터(10)가 결합되고, 하부포스트(B) 상단 내부에 설치된 링기어와 맞물리며 유압모터(10)에 의해 회전하는 피니언(12)을 갖는 슬루윙 윈치(f1)로 상부프레임(C)을 360°회전시키는 것을 특징으로 하여, 이동이 거의 필요치 않으며, 반복작업을 필요로 하는 곳에 설치사용함으로서, 종래의 경유를 연료로 하는 엔진과, 이동을 위한 궤도가 설치되어 있는 이동식 버켓크레인에 비하여, 크레인의 제작비용을 50%이상 절감할 수 있을 뿐만아니라 엔진이나 궤도가 구성되어 있지 않아, 엔진이나 궤도의 먼지, 분진에 의한 고장위험이 없으며, 작동연료를 경유가 아닌 전기를 사용하게 됨으로서, 작동비용을 절감할 수 있는 전동식 버켓크레인을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to devise to improve the various problems as described above, the bucket (a1) and the bucket (a1) to allow the target to be transported, such as soil, industrial waste, and the long distance of the bucket (a1) A movable part A composed of a boom a2 for enabling work and a hydraulic cylinder a3 for operating the boom a2; A lower post B for supporting the upper frame C and fixing the bucket crane to a work place; An upper frame C installed at an upper portion of the lower post B to support a control cabin D, an oil tank E, an electric motor F, and the like; A control cabin (D) installed at an upper end of the upper frame (C) to control the operation of the entire bucket crane; An oil tank E provided therein for supplying oil to the hydraulic cylinder a3; An electric motor (F) connected to the hydraulic pump (13) by a connecting shaft to generate hydraulic pressure in the hydraulic pump (13); The hydraulic motor 10 operated by the oil supplied from the hydraulic pump 13 is coupled, and has a pinion 12 engaged with a ring gear installed inside the upper end of the lower post B and rotating by the hydraulic motor 10. It is characterized by rotating the upper frame C 360 ° with the slewing winch f1, which requires little movement and is used where it is necessary for repetitive work. Compared with the mobile bucket crane which has a track for the purpose, the manufacturing cost of the crane can be reduced more than 50% and the engine or track is not configured, so there is no risk of failure due to the dust or dust of the engine or track. The purpose of the present invention is to provide an electric bucket crane that can reduce operating costs by using electricity instead of diesel fuel.
