A construction system includes: a position data acquisition unit configured to acquire position data of a bottom of water; a current-terrain data generation unit configured to generate current terrain data of the bottom of water based on the position data; a target-terrain data generation unit configured to generate target terrain data of the bottom of water based on the current terrain data; and a working equipment control unit configured to control a working equipment of a work vehicle based on the target terrain data.

Construction system and construction method

A self-traveling crushing machine includes: a traveling device; a crushing device that is provided on the traveling device and crushes a to-be-crushed object supplied; an overload escaping section that escapes an overload of the crushing device; and a controller that controls the crushing device. In the self-traveling crushing machine, the crushing device is a jaw crusher in which the to-be-crushed object is supplied to a V-shaped space formed by a fixed jaw and a movable jaw and the movable jaw swings relative to the fixed jaw to crush the to-be-crushed object, and the controller includes: an escape-operation determining section that determines whether or not the overload escaping section has operated; and an information output section that sends the escape operation information to an outside when the escape-operation determining section determines that the escape operation has been conducted.

Self-propelled crusher and management system for self-propelled crusher

A jaw crusher includes: a crusher frame to which a cross member for connecting a pair of side wall plates is provided; a fixed jaw; a swing jaw swingably hung between the side wall plates; a pair of toggle link pins both of which are disposed along a common axial direction having a first outer end pivoted on the side plate and a second inner end pivoted on a main supporter provided to the cross member; and a reaction force-receiving link mechanism including a toggle link rotatably supported by the toggle link pin. The main supporter of the cross member on which the second end of the toggle link pin is pivoted is box-shaped.

Jaw crusher and self-traveling crusher

In a jaw crusher, cheek plates are mounted on side wall plates of a crusher frame by mounting bolts, and the mounting bolt adjacent to the outlet of the jaw crusher can be covered with the swing jaw by adjustment of an outlet gap-adjusting link mechanism. When the jaw crusher is in operation, the mounting bolt is covered by the swing jaw to avoid contact with raw materials, so that abrasion of and damages to the mounting bolt can be prevented. Thus, a longer lifetime of the jaw crusher can be promoted. Besides, since abrasion of and damages to the mounting bolt can be prevented, a mounting structure of the cheek plate can be stronger.

A jaw crusher is provided that includes a toggle plate holder mechanism, provided without increasing the overall height thereof, and a reaction force receiver link mechanism of an up-thrust type. A tension link mechanism acts as the toggle plate holder mechanism and includes a link having a tension link, a tension lever, a tension rod, and a tension spring. The layout angle of the tension link and tension rod can be changed freely by the tension lever.

Jaw crusher and self-propelled crushing machine having the jaw crusher

A jaw crusher capable of stable angle detection is provided. For this purpose, the jaw crusher includes a fixed jaw (), a swing jaw () provided to oppose the fixed jaw, a frame () for supporting the fixed jaw and the swing jaw, and an outlet clearance adjusting mechanism () for adjusting an outlet clearance between the fixed jaw and the swing jaw, and the outlet clearance adjusting mechanism includes a connecting member () of which one end is made abut to or connected to the swing jaw, a rotatable rotary member () which is made abut to or connected to the other end of the connecting member, a driving mechanism () for rotating the rotary member, and angle detecting equipment () which is mounted to the frame and detects a rotation angle of the rotary member.

Jaw crusher

A compact and light-weight jaw crusher, in which life span of parts enduring abrasion is long, and an outlet clearance of a crushing chamber is easily adjusted, is provided. For this purpose, the jaw crusher includes a stationary jaw ( ) fixedly provided at a frame ( ), a movable jaw ( ) which is provided to oppose the stationary jaw and attached swingably with an eccentric drive shaft ( ), a movable jaw load receiving section ( ) attached to the frame, and a coupling joint ( ) which is a connecting member for connecting a lower portion of the movable jaw and the movable jaw load receiving section and swingably connects the lower portion of the movable jaw and the movable jaw load receiving section.

An outlet clearance adjustment mechanism of a jaw crusher, which is small in size, simple in structure, and capable of reducing outlet clearance adjusting time, is provided. For this purpose, the outlet clearance adjustment mechanism includes a toggle block ( ) having a downward inclined plane ( ), a toggle block frame ( ) having a mounting surface ( ) on which the toggle block ( ) is slidably mounted and an inclined plane ( ) provided to oppose the downward inclined plane ( ), a detachable clearance adjustment shim ( ) provided between the opposing downward inclined plane ( ) and the inclined plane ( ), and the hydraulic type of mechanical lock cylinder ( ) provided at a back side of the inclined plane ( ) of the toggle block frame ( ).
