摘要： PROBLEM TO BE SOLVED: To prevent the intrusion of rolling stones between gear of a motive wheel and a link by providing a hinge part in each core of a front and a rear side, and connecting the hinge parts of the adjacent cores with a removable hinge pin, and forming length of the hinge part for connecting adjacent cores larger than the width of a left and a right operating surface parts. SOLUTION: Multiple elastic track shoes are arranged in the longitudinal direction of a crawler, and adjacent cores 10, 10 are connected to each other by inserting a removable hinge pin 11 into hinge parts 10a-10d. With this structure, a clearance between the adjacent elastic track shoes is formed small, and intrusion of rolling stones between gear of a motive wheel and the core 10 and the operating surface part 10A can be prevented. Furthermore, in the hinge parts 10a-10d of the core 10, an opening part A is provided between an engagement part 10B, which is larger than the fitting width of the left and the right operating surface parts 10A, 10A and which is integrally formed with the left and the right operating surface parts 10A. 10A, and the hinge part 10c. Since the soil is discharged from this opening part A, stay of the soil in the periphery of the cores 10, 10 and the operation surface parts 10A, 10A can be prevented, and applying of a heavy load to the elastic track shoes can be prevented.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost as a whole by forming a fitting part of a window plate to have a shape including the whole body so as to make it possible to form a plurality of kinds of windows having mutually overlapping part and non-overlapping part. SOLUTION: A window opening is formed at the fitting part 9 of a window plate whose peripheral edge is shaped stepwise and formed recessively or protrusively and the window plate covering these openings is attached to the fitting part 9 to form windows 7A, 7B. In this case, the fitting part 9 of the window plate is formed to have a shape including the whole body of the overlapping part and the non-overlapping part of these windows 7A, 7B so that the windows 7A, 7B comprising at least two kinds of shapes having the mutually overlapping part and the non-overlapping part can be formed respectively. In this way, even when cabs for different kinds of machines, having mutually different shapes from each other are manufactured, the manufacture cost can be reduced as a whole.

摘要： PROBLEM TO BE SOLVED: To prevent crack and separation due to contact by setting up a metal plate, which is locked tight to a link at a link surface side, and also attached to a tension member via a bolt at a tension member side, in the interval between the link and the tension member. SOLUTION: An elastic track shoe 10 made up of covering a tension member 1 with an elastic body 2 under welding, is set up in the longitudinal direction of a crawler. A symmetrical pair of links in contact with the tread of each track driving roller superpose two adjacent links in the longitudinal direction of the crawler, connecting them together with a pin 4. A link 3 and a metal plate 6 are integrally joined together by means of welding, and an insertional hole into which a bolt 5 is inserted is installed in this metal plate 6. The tension member 1 is provided with a tapped hole for this bolt 5. The metal plate 6 and the tension member 1 both are installed through the bolt 5. The elastic body 2 of the elastic track shoe 10 is formed into such a trapezoidal form as being successively reduced toward both right and left ends from the central part, and thereby a shear of earth and sand becomes enlarged in all directions by inclination, generating a tractive force. It is so structured as to take it with the tapped hole 1a, and a head part of the bolt is exposed at the side of a noncontact surface, therefore the bolt head and the elastic body will not come into contact with each other, and thus durability is improved.

摘要： PROBLEM TO BE SOLVED: To provide an operation cab in a construction machine by a method wherein not only the work efficiency but also habitability and convenience at getting on and off is improved by a simple construction without complicating the construction of the operation cab so that better functions can be produced. SOLUTION: In the construction machine, a revolving base is provided on a running frame and an operation cab l is mounted on one side of the revolving base. In this case, a front window 3 having a chevron-shaped cross section is integrally provided so as to extend from the front of the cab 1 to a part of a side thereof, and a door 10 is formed in such a manner that the front window 3 is forwardly expanded so as to clear a front side column supporting the curved side end of the window 3, so that the door 10 can be moved and stored along the outside of the cab 1, and an opening is used as an entrance of the cab 1.

摘要： PROBLEM TO BE SOLVED: To certainly check the invasion of sediment into a truck frame by forming the truck frame in a downward U-shape, and filling up reinforcing material in a space between the truck frame and a truck roller. SOLUTION: In a state where a truck frame 2a formed in a downward U- shape and a truck roller 3c are mutually assembled, a reinforcing material 2A is filled up in a space inside the truck frame 2a. Since the truck frame is thus composed, sediment flung up from a shoe 3a and a link 3b can be checked from entering through a gap between a truck roller guide 2b and the link 3b into a U-shaped opened part at the lower end of the truck frame 2a. The sediment is thereby discharged below the truck roller 3c, which assists the shoe 3a in its smooth rotation, and the early abrasion of the truck roller 3c and the deformation of the truck frame 2a which are caused by the sediment piled up inside the truck frame 2a can be prevented.
