    摘要： The post driver with limited movement floating post anvil does not rely heavily upon the skill of the operator to efficiently drive posts. The post anvil is allowed to move up and down in relation to the driver, but its movement is limited by both lower and upper fixed barriers. Since the movement is limited, the operator can position the driver upon the post allowing the full weight of the driver framework/carrier machine to rest upon the post. The post would push the floating post anvil upward only to the point at which the upper fixed barrier prevents further upward movement of the floating post anvil. Thus, once the floating post anvil abuts the upper fixed barrier, substantially the entire weight of the post driver is resting on the post.

    摘要翻译： 有限运动漂浮砧座的后驾驶员不会很大程度上依赖于操作员有效驾驶岗位的技能。 砧座被允许相对于驾驶员上下移动，但其运动受到上下固定障碍物的限制。 由于运动受到限制，操作员可以将驾驶员定位在车柱上，从而允许驾驶员框架/运载机的全部重量放置在车柱上。 该柱将浮动砧座向上推动到上部固定屏障防止浮动砧座进一步向上移动的点。 因此，一旦浮动砧座抵靠上固定屏障，基本上整个重量的后驱动器就位于柱上。

    摘要： A hydraulic pick has a supporting body with a piston and a piston rod fixedly positioned in the supporting body. A working tool is driven by a short, axially rigid striking pin, guided in a bushing. A pressure transformer cylinder and an equalizing chamber are formed between the piston rod and a pressure transformer piston. The striking pin is driven by a working fluid under pressure, which is distributed by a system of channels in the piston rod.

    摘要： A motor controller comprises a processor selectively outputting an on-signal to either one of an upper arm switching element and a lower arm switching element based upon a detected position by the position sensor, gate drivers inputting a driving voltage to the gates of the switching elements by shifting a level of the on-signal from the processor to the upper arm switching element and a bootstrap capacitor configured to be charged while the upper arm switching element is turned off and to behave as a voltage supply for the gate driver while the upper arm switching element is turned on. The processor is configured to reduce a set duty ratio when the set duty ratio is equal to or larger than a predetermined value (e.g. 80 percents) and a rotational position of the motor does not change for a first predetermined time. This motor controller can prevent the switching element from a burnout even if the motor is locked.

    摘要： A forced entry tool is disclosed that includes a two-sided hammerhead and provides a mechanical advantage to breach burglar bars and locks, yet is strong and portable. The two-sided hammerhead provides greater positional stability that reduces the necessity to reposition the tool. A two-sided hammerhead is attached to one end a guide rod, while a guide case with handles is encased over the guide rod. A striking base is attached to the guide rod near the end opposite to the hammerhead. The hammerhead is then positioned behind the burglar bars. The case is then moved forcefully over the guide rod, towards the striking the base. This repeated action of striking the base will then defeat the bolts, welds, locks, and bars through leverage and mechanical advantage.

    摘要： A hand held power tool has a housing, a motor, a power source, a cam shaft, a hammer, an integrated anvil-gear, a second gear, and an output. The motor is disposed in the housing and has a motor axis. The power source energizes the motor. The cam shaft is driven by the motor and the hammer is driven by the cam shaft. The integrated anvil-gear has an anvil end and a first gear end, and the anvil end is impacted by the hammer. The second gear engages the first gear end and defines an output axis that is at a predefined angle with respect to the motor axis. An output is coupled to the second gear.
