    Abstract: A kit of portable modular components for use in demountably configuring a variety of structural assemblies. The kit comprises three types of elongate structural support components wherein the first type has a pair of opposed male ends, the second type has a male end and an opposed female end, and the third type has a pair of opposed female ends, wherein the male ends are configured for demountable engagement with the female ends. Each of the male ends comprises a cylindrical body with at least one linear set of two spaced-apart prongs around the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels for receiving therein the cylindrical body and the at least one linear set of prongs. The female ends are provided with locking assemblies for releasable engagement the male ends.

    Abstract: A construction machine allows a worker to easily move between one pair of side frames through a travelling body weight. The construction machine includes a lower travelling body of a crane includes a truck frame, a left side frame and a right side frame, a front weight and a rear weight, and scaffolding members. Scaffolding upper surface parts of the scaffolding members and upper surface parts of the front weight and the rear weight are disposed in line with each other along a left and right direction, and form a moving passage that allows the worker to move between the left and right side frames.
