摘要： A construction machine having a device for attaching and detaching a counterweight according to the present invention comprises a lower traveling body; an upper rotating body mounted rotatably on the lower traveling body; the upper rotating body having a support bed standing out from a rear part thereof; and a device for attaching and detaching a counterweight mounted on the support bed. The attaching and detaching device comprises a telescoping device having a lower end pivotally connected in the vicinity of the support bed, a restiform body suspended through a guide portion provided on the telescoping device; and oscillating structure for oscillating the telescoping device around the lower end as fulcrum. The oscillating structure displaces the telescoping device extended from a substantially vertical attitude to an inclined attitude when the counterweight is detached. According to the present invention, an inclined bed is not required, and locating of the counterweight to the support bed can be done easily.

摘要： A construction machine having an engine arranged along a counter weight, wherein the intake air pipe of the engine is passed between the counter weight and the engine without the need of installing the counter weight spaced from the engine, so that the counter weight protrudes outwardly less. This is accomplished by a piping space (44) of a recessed shape formed in the surface (36) of the counter weight (18) facing the engine (4) allowing the intake air pipe (28) to pass therethrough.

摘要： Construction equipment such as an excavator is provided with a counterbalance assembly positioned at the aft end of the construction equipment. The counterbalance assembly includes a pair of enclosures and a counterweight. The pair of enclosures is separated by a back panel and a bottom panel connected to opposed side walls of the enclosures. The back panel, the bottom panel and the opposed side walls form an aperture for receiving the counterweight. The pair of enclosures and the counterweight are separable from each other and from the construction equipment to enable transportation of the construction equipment apart from the pair of enclosures and the counterweight.
