The present invention relates to a crane pad which is put under a jack of an outrigger unfolding in all four directions from a crane vehicle to prevent the ground subsidence, vehicle overturn, and road damage. According to the present invention, the crane pad comprises: a rectangular main frame made of an upper plate, lower plate, and side plates; a support plate dividing the inside of the main frame evenly to form a large number of hollow parts; an antiskid rubber installed on the upper plate of the main frame; a cover with a handle, which covers the hollow part on a front side and a rear side of the main frame; and a flat iron piece attached to a lower surface of the main frame. The crane pad is lighter, safer, and easier to handle than the conventional crane pad which has been made of wood or iron plates. When manufacturing the crane pad, the pad is cut into a needed length forwards and backwards after performing an extrusion molding, and two or more main frames are engaged with a joint bar to extend the main frames as desired towards a left side and a right side. The support plate is formed vertically or diagonally to keep the strength and have different thicknesses. Accordingly, the present invention is able to easily manufacture the crane pads of various standards.

    본 발명은 크레인차량에서 사방으로 전개하는 아우트리거의 잭 하부에 깔아 지반침하, 차량전도, 도로파손을 방지하는 크레인 받침대에 관한 것이다. 본 발명에서는 상판,하판,측판으로 이루어진 장방형 본체와, 상기 본체의 내부를 일정하게 구획하여 다수의 중공을 형성하는 지지판과, 본체 상판에 설치하는 미끄럼방지고무와, 본체 전후의 중공을 덮는 손잡이 달린 커버와, 본체 하부면에 부착한 평철로 구성하여 기존의 목재 또는 철판으로 대용하던 크레인 받침대에 비해 가볍고 안전하며 취급이 용이한 크레인 받침대를 제공한다. 크레인 받침대 제작시, 압출성형하여 전후방향으로 필요한 길이로 자르고, 두개 이상의 본체를 조인트바로 결합하여 좌우방향으로 원하는 길이만큼 늘리며, 지지판을 수직 또는 사선으로 형성하여 강도를 유지하면서 서로 다른 두께로 만들 수 있다. 이로써 다양한 규격의 크레인 받침대를 쉽게 제작하는 것이 특징이다.
