摘要： PROBLEM TO BE SOLVED: To dispense with the consideration on interference with a guard frame in installation of a truck-mounted crane and a loading space on a truck, by standing the guard frame at a rear side of a post on a crane base with the minimum clearance necessary for preventing the interference with the post in the revolving of the post. SOLUTION: A guard frame 10 is mounted on a crane base 4 at a rear side of a post 6 with the minimum clearance necessary for preventing the interference with the post 6 in revolving of the post 6. According to this construction, as the guard frame 10 is mounted on the truck-mounted crane B, it becomes unnecessary to consider the interference with the guard frame 10 when the truck-mounted crane B and the loading space 2 are installed on a truck A. Accordingly, the trouble in the installation of the crane B and the loading space 2 onto the truck A can be solved.

摘要： PROBLEM TO BE SOLVED: To easily lengthen a boom by arranging a lug in an upper frame of a main body receiving part, connecting a lower end of a rope fitted to the lug to an auxiliary weight placed on the ground, and contributing the weight as a stabilizing moment when a long boom is derricked. SOLUTION: In addition to a standard weight 12, a lifting auxiliary weight 13 placed on the ground from a lug 16 installed to the rear part of an upper frame 14 is connected to a supporting rope 17 (substitutional with a link, a chain block or the like). When a long boom is derricked, a shortage of stabilizing moment on the main body side can be supplemented with additional moment by means of the auxiliary weight 13. When the supporting rope 17 is not in use, the auxiliary weight 13 is removed and only the supporting rope 17 is housed on the main body side.

摘要： PROBLEM TO BE SOLVED: To improve manufacture and workability and to prevent the removal of a lower frame end part from a guide port by locking the other end of a link in the lower frame simply by a pin. SOLUTION: During crane work, a cylinder is extended while a pin is pulled out from a link, and a side frame 12 is bulged. The side frame 12 is fixed in this bulged position by inserting the pin into the hole of the link. Then, a bolt 45 is fastened, and a tapered block 43 is moved in a right direction. Thus, a relative distance between the tapered blocks 43 shrinks, heights thereof are continuously increased to fill gaps S. The crane work is done while the gaps S are filled, and the shaking of an upper rotary body is suppressed.

摘要： PROBLEM TO BE SOLVED: To slowly move a hydraulic actuator by providing a crane work switch and a delivery reducing means to reduce a maximum delivery of a variable displacement hydraulic pump when this is turned on in a hydraulic shovel having a crane work mode. SOLUTION: When a crane work switch 30 operated by an operator is turned on, an electric current is carried to a control pressure output valve 40b of a delivery reducing means 40 to outpout control pressure from a solenoid proportional pressure reducing valve of the control pressure output valve 40b. Then, this control pressure is outputted to a signal oil passage by being selected by a shuttle valve 40a to regulate a maximum delivery of a variable diaplacement hydraulic pump 14. At this time, when a detecting signal is outputted from a work range detecting means 51, a solenoid proportional pressure reducing valve of a pilot oil control valve 50a is excited. Therefore, pilot oil is discharged to a drain by being reduced by the pilot oil control valve 50a, so that extending directional actuation of a boom cylinder 8d is reduced and stopped.

摘要： PROBLEM TO BE SOLVED: To provide a structure which ensures that inclination and shaking which result from a gap between the side frame and the lower frame of a crawler type traveling body can be prevented through a simple operation. SOLUTION: A bolt 22 is rotated in a predetermined direction and a lower frame end 11a is pressed down by the end of the bolt 22 to cause the lower inside surface 13a of a guide slot 13 to abut to the lower frame end 11a. The movement of the lower frame end 11a brings a gap close to the upper inside surface 13b of the guide slot 13 to provide a maximum gap S. Under this state, shim plates 23 are inserted into a shim plate mounting part 24 by the required number and secured to a side frame 20 by screws 26, with an anti-popping-out plate 25 fitted into a recess part 23a.

摘要： PROBLEM TO BE SOLVED: To prevent interference between a swinging body and other machines without adding a counter-weight. SOLUTION: A machine for foundation work comprising a traveling body 1, a swinging body 3 coupled to a predetermined shaft of the traveling body 1 in a rotatable manner around the center O of swinging and an excavating attachment provided at the swinging body 3 for excavating the ground almost vertically. In this case, the swing body 3 is constituted in such a manner that the maximum swinging radius R is less than the distance from the center of swinging to the end portion of the traveling body in a front-rear direction.
