Description

  The present invention makes it easy to appropriately replace only a pinched portion such as an arm attached to the tip even in an extremely narrow place such as a narrow space in a compact multifunction machine for construction attached to the tip of a boom of a plurality of hydraulic excavators. The present invention also relates to a table for storing a plurality of pinched portions that can be quickly performed.

  Conventionally, various types of crushers, cutting devices, and the like exist as devices for crushing buildings such as concrete structures and high-rise buildings. However, in recent years, the business itself of crushing and redeveloping concrete structures and the like has decreased, but rebuilding of small-scale steel structures such as convenience stores and residential general houses is frequently performed.

  The land where this convenience store is installed is located in the city and some busy streets, which is not only a confined area, but also restricted by noise. Structures such as convenience stores have light steel frames and concrete foundations that need to be crushed.

  It is necessary to be able to cut steel frames and the like with a small crusher and to crush concrete, and in order to obtain a predetermined torque, a structure with a hydraulic cylinder is essential. However, its large size is not necessary, but at least the two objectives of steel cutting and concrete crushing must be achieved.

  There are two possible ways to achieve this goal. The first is to prepare two dedicated machines (steel cutting machine or crushing machine) as in the past, but this not only makes the price expensive, Due to the urban area, oil leakage during the replacement of hydraulic hoses was a serious problem in terms of environmental pollution.

  Secondly, it is conceivable that only one multifunction device main body is provided so that only a pinched portion such as an arm attached to the tip can be replaced. This is a completely new matter for the industry. If it is easy to replace only the pinched parts such as the arm in this way, oil leakage will not occur without replacing the hydraulic hose, which is preferable from the viewpoint of environmental pollution and shortening the replacement time. Will be realized. In Patent Literature 1, even if it is called a table or moved up and down, it is moved while riding on it, and there is no configuration in which the table itself rotates.
