摘要： An excavating apparatus having a prime mover with a longitudinal centerline and a main frame with an engine, a ground drive system and an excavation boom operatively attached thereto wherein the excavation boom has a first end and a second end. The first end of the boom is operatively pivotally attached to the main frame along a main frame pivot axis. The main frame pivot axis is transverse to the longitudinal centerline of the prime mover. A head shaft operatively rotatably attached to the second end of said boom and is operatively pivotally attached to the second end of said boom. Also, the excavation drum is mounted onto the head shaft in a manner that the excavation drum cooperates with the excavation chain and a fixed cutter pattern of the excavation chain to stay in consistent alignment with the fixed cutter pattern of the excavation drum.

摘要： Excavating equipment comprising a rigid support structure with articulately mounted surface clamps, an excavating device downstream of the surface clamps in a direction of excavation and an urging device for urging the excavation means in a direction of excavation during excavating. The equipment further comprises a power device coupled to the excavating device for operating same and for operating the urging device. The power device is also coupled to the surface clamps for laterally displacing the surface clamps against rigid supporting surfaces so as to generate a counter-reaction to forces generated by operation of the excavating device. Additionally, a displacing device is coupled to the support structure for displacing the equipment into and out of an excavation. Alternatively, when the equipment is used for excavation in rocky sites, the equipment can comprise a first rigid support structure and a second rigid support structure articulated to the first structure, with an expansion device for displacing the second rigid structure with respect to the first structure, and with the equipment further comprising a power device coupled to the rotary milling cutters for operating same.

摘要： A mounting arrangement for supporting a bulldozer blade on a vehicle having a C-frame wherein the blade is supported by a centrally located universal ball joint on the C-frame and a pair of longitudinally arranged hydraulic jacks. In addition to providing a simplified three-point mounting for the blade, blade angle and pitch may both be controlled by the single pair of jacks. Preferably, a generally horizontally tilt cylinder is pivotally connected between the back of the blade and a tower structure on the C-frame to stabilize the mounting structure and provide means to tilt the blade.

摘要： The present invention relates to a drive device for a diaphragm wall cutter (1), having a drive housing and/or gear housing (11), which encloses an interior (16) for accommodating drive and/or gear elements and comprises two housing parts (13, 14) which are rotatable relative to one another and which are sealed with respect to one another by a sealing device (15), and having a pressure equalization device (19) for pressure equalization between the interior and the surroundings. The invention also relates to a diaphragm wall cutter having such a drive device. It is proposed here not to pressurize the entire interior of the housing, but only an interspace (20) arranged upstream with respect to the surroundings, and to seal said interspace with respect to the interior on the one hand and with respect to the surroundings on the other hand. According to the invention, the pressure equalization device comprises at least one intermediate chamber (20), which is pressurized by a pressure source and is sealed with respect to the interior by an inner seal (21) and with respect to the surroundings by an outer seal (22). By virtue of such a sealed intermediate chamber between the housing interior and the surroundings that can be considerably smaller in terms of volume than the interior, the pressurization for pressure equalization between interior and surroundings is considerably simpler.

摘要： A 3D volume rate control method and apparatus (10) for a slewing bucket-wheel stockpile reclaimer 16 is described. The apparatus (10) comprises four 3D image sensors (12) mounted adjacent a bucket-wheel (14) of the (reclaimer 16), which are adapted to provide 3D images of a stockpile bench face. The apparatus includes a data processor (20) for: (i) processing the 3D images produced by the 3D image sensors (12) to generate a 3D stockpile bench face profile, (ii) calculating a reclaim cut volume rate at which material is being cut from the stockpile face based on a measured change in volume of the 3D stockpile bench face profile in the area abutting the excavation tool, (iii) calculating a reclaim cut volume of material that will be cut from the stockpile face based on the shape of the excavation tool and the 3D stockpile bench face profile to determine a feed forward reclaim cut volume rate profile, and (iv) calculating an operating parameter for the reclaimer based on a desired reclaim cut volume rate compared to the measured reclaim cut volume rate and the feed forward reclaim cut volume rate profile. The method and apparatus provide accurate reclaim volume measurement so that the reclaim volume rate becomes independent of the product characteristics, stockpile bench face shape and bucket-wheel cutting parameters.

摘要： A system is used with a boom pivoted on a frame about a horizontal pivot axis between raised and lowered positions by a first fluid ram joining the frame and the boom. A releasable locking mechanism locks the boom relative to the frame to prevent pivotal movement of the boom about its horizontal pivot axis. A second fluid ram is disposed between the frame and the boom, the second fluid ram compressed between the frame and the boom when the boom is adjacent the raised position, but prior to the boom achieving a latched position substantially coinciding with the raised position. A fluid circuit of the second fluid ram has two selectable pressure levels. The first level substantially prevents the boom from achieving the latched position, the second level permits the boom to achieve the latched position while providing fluid cushioning to dissipate impact forces between the boom and frame.
摘要翻译：一个系统用于通过连接框架和起重臂的第一流体柱塞枢转在框架周围水平枢转轴线在升降位置之间的臂架。可释放的锁定机构相对于框架来锁定吊臂，以防止吊杆围绕其水平枢轴枢转运动。第二流体柱塞设置在框架和悬臂之间，当悬臂与升高位置相邻时，但在起重臂实现与升高位置大致一致的锁定位置之前，第二流体柱塞在框架和悬臂之间被压缩。第二流体柱塞的流体回路具有两个可选择的压力水平。第一级基本上防止起重臂实现闩锁位置，第二级允许吊杆实现闩锁位置，同时提供流体缓冲以消除吊杆和框架之间的冲击力。
