摘要： A method for using a tool to extract tent stakes from the ground is disclosed. The tool has a portion that houses the motor and hydraulic fluid tank, and a hydraulic cylinder portion the user holds against a tent stake and operates to pull the tent stake. Hydraulic hoses connect the two portions. Separating the motor from the hydraulic cylinder allows the user to manipulate just the portion performing work on the tent stake without having to also lift or stabilize the larger and heavier motor portion. Rotating a handle causes the hydraulic cylinder to extend or retract. A hand guard may be present to prevent accidental crush injuries. The tool is designed to fully extract a stake in two strokes of the hydraulic cylinder.

摘要： A post puller features a lifting member that is slidably disposed on a guide shaft and attachable to a lifting arrangement of a working machine. A pair of movable grippers are pivotally supported on the guide shaft at a fixed position therealong, and a pair of links are pivotally connected between the lifting member and the grippers. With a web or flange of the post received in a space between inner ends of the movable grippers, raising of the lifting member by the working machine lifts the outer ends of the movable grippers via the pair of links, thereby lowering inner ends of the grippers into closer proximity to one another to grip the web or flange of the post between the grippers. With the post gripped in this manner, further raising of the lifting member by the working machine pulls the post from the ground.
摘要翻译：后拉拔器具有提升构件，其可滑动地设置在引导轴上并且可附接到作业机械的提升装置。一对可移动的夹持器在其一侧的固定位置枢转地支撑在引导轴上，一对连杆被枢转地连接在提升构件和夹具之间。由于柱的腹板或凸缘容纳在可动夹持器的内端之间的空间中，所以提升构件通过工作机构的升高通过一对连杆提升可动夹持器的外端，从而降低夹持器的内端彼此更接近地夹紧夹持器之间的腹板或凸缘。在以这种方式夹紧柱的情况下，工作机械进一步提升提升构件将桩从地面拉出。

摘要： A fence post removal device is provided which provides a simple mechanical device to allow a person to remove a fence post from an installed position within the ground. The device allows the person to sit atop a machine like a tractor or front loader, position the device over an exposed end of the fence post, and lower the device such that an internal guide causes the device to self-align with the top of a fence post which passes through the device a specific distance before coming into contact with a bumper which prevents the device from dropping too close to the ground.

摘要： An extraction device eases the task of removing a post, bush or the like from a ground surface. The device includes a pair of legs pivotally coupled together at respective first ends of the legs. A bar is pivotally coupled to a first one of the pair of legs. The bar has a notch extending upwardly into a bottom edge of the bar. A projection is coupled to a second one of the legs. The projection is insertable into the notch to secure the legs in a static position relative to each other. A connector is coupled to an associated one of the legs proximate the first end of the pair of legs. A ratcheting mechanism is removably coupled to the connector. A cable is removably coupled to the ratcheting mechanism for extending around a structural object for removing the structural object from the ground surface.

摘要： The present invention is directed to an anchorage extractor. The extractor is used to remove post, anchorage or stake from the ground without using a force generated by a motor. The anchorage extractor comprises a base disposed on the ground to provide a stable support. A lever is connected to a driving wheel that is connected to a rack. The anchorage is attached to the rack and when the lever is actuated, the drive wheel drives the rack upward, removing the anchorage from the ground. An advantage of the present invention is that the direction of the extraction force is parallel to the anchorage axis by adjusting the angle of the extractor. The extractor may be folded on itself or dismantled to be transported.
