摘要： PROBLEM TO BE SOLVED: To provide an elevating mechanism of simple structure, having good working efficiency and capable of generating stable elevating/ sinking motions, and provide a construction machine equipped with such elevating mechanism. SOLUTION: An elevating mechanism 1 includes a mast of variable length varied by increasing or decreasing the number of coupled structural bodies 8 constituting the mast, and a telpher (construction machine) supported by its upper part is elevated and sunk, wherein the configuration is composed of an under-frame 2 supporting the legs 30 of the telpher, a coupling means 3 installed on the under-frame 2 and coupling it with unit structural bodies 8, four jacks 4, and over-frame 5 to support the jacks 4. Each jack 4 consists of a cylinder 41 equipped with a piston rod 42, and the forefront mounting part 43 of the piston rod 42 is fixed to a bracket 22 of the under-frame 2. If the piston rods 42 are contracted in the condition that coupling by the means 3 is disengaged, the under-frame 2 and telpher supported fast thereby are raised.

摘要： PROBLEM TO BE SOLVED: To surely prevent the content of a bucket from dropping through the biting part or opening part of the bucket by grasping a target by a bucket consisting of a lateral pair of shells, and covering the biting part and opening part of the bucket with a cover material. SOLUTION: This device is provided with an arm 3 having a roller having a cover material 2 wound thereon, and the shells 1 of a bucket are opened and closed in the state where the arm tip 8 is situated above the shells 1 or a position A to catch earth and sand. When the shells 1 are closed with the earth and sand being caught therein and the bucket is hoisted upward, the arm 3 is extended over a position B or a rocking position where the arm tip 8 can pass the farthest part (positions C, E) of the shells 1, and a rocking motor 4 is rotated to move the arm 3, so that the bucket opening part is covered with the cover material 2. Thereafter, the cover material 2 is tensed by the action of a spring and closely fitted to the outer surfaces of the shells 1 to prevent the drop of the content of the bucket.

CONSTITUTION:A steel frame support body 3 having a cylindrical support frame is erected on a base body 2, and an adjustable leg body 9 is fitted to the outside of the frame 6 via a plurality of stays 8, thereby forming a jig device 1. Thereafter, the predetermined number of the jig devices 1 are arranged on the concrete layer 20 of a rigidly compacted foundation at ultra-accurate intervals, and the base body 2 is secured with anchor bolts. Then, the lower end of a steel frame column body A is inserted and fixed to each support frame 6, and a steel frame B for a beam is jointed between columns A, thereby forming a block. This block is removed from the jig devices 1 and carried to the predetermined position for installation. According to the aforesaid construction, the block for an ultra-high building can be accurately fabricated on the ground, and a construction period can be shortened.
