摘要： PURPOSE: To dig a groove along the top of slope of banking and the end edge of a road easily by use of a trencher and to faciliate back filling. CONSTITUTION: In the case where the top of slope of banking and the end edge of a road is located on the left (L) of a trencher 11, an upper rotary body 13 is rotated only in a +θ arc, and a trencher attachment 28 is rotated only in a -θ arc. Thus, the trencher attachment 28 is offset to the outside end part of a left crowler 14. A right hand screw 35 is installed as an earth removal screw. The trencher 11 is shifted to the top of slope and the end edge of a road to dig a groove 38. All the excavated sediment is displaced to the right (R) of the trencher by the right hand screw 35.

摘要： PURPOSE:To execute a work from digging of a groove to backfilling by means of one set of machine so as to remarkably improve working efficiency by scraping together earth and sand discharged on both sides of a digged groove with a blade provided on the rear part of a running machine body. CONSTITUTION:The ground in front of a running machine body 12 is digged by means of a trenching device, and earth and sand is discharged on the ground. Next after executing a work such as arrangement of cable in a digged groove 22, by advancing the running machine body 12, earth and sand discharged on the both sides is pressed with the right and left both end parts 24a, 24b of a blade 24 so as to be scraped together to the center part 24c, and hence the groove 22 is backfilled. In this case, surplus earth and sand 39 is escaped rearward through an opening hole 29 provided on the center lower part of the blade 24. A quantity of earth and sand passing the opening hole 29 is adjusted by moving up and down a weir 31 up/down adjustably provided on the opening hole 29.

摘要： PROBLEM TO BE SOLVED: To quicken the arm expansion speed at the time of arm expansion operation, with regard to a hydraulic circuit for expanding and contracting a multistage type telescopic arm by means of two cylinders making a tuning actuation, by regenerating return oil and supplying it to one of the cylinders without increasing pressure loss in the line on the arm expansion side. SOLUTION: An outer cylinder 3a and an intermediate cylinder 3b of a telescopic arm 3 is connected together by a first cylinder 6 and the intermediate cylinder 3b and an inner cylinder 3c are connected together by a second cylinder 7. An A chamber on the rod side of the first cylinder 6 is communicated with a B chamber on the tube side of the second cylinder 7 by a communication line 8. A C chamber of the first cylinder 6 and a D chamber of the second cylinder 7 are connected together by a regeneration line 13 and an open/close valve 14 is intervened in the midway of the regeneration line 13. The operation speed of the two cylinders is speeded up and the expansion speed of the telescopic arm 3 is quickened because the C chamber communicates with the D chamber with the open/closed valve 14 being opened by the pressure from the C chamber at the time of arm expanding operation and some of the return oil to the line 11 on the arm contraction side is regenerated from the the second cylinder 7 to the first cylinder 6 through the regeneration line 13.
