摘要： A die cutting machine has a mobile stair (14), the mobile stair (14) being able to assume a retracted position and an extended position, wherein in the extended position the mobile stair (14) is accessible by an operator. The mobile stair (14) is configured to be pushed into the retracted position by a transport rack (16) and pulled into the extended position when the transport rack (16) is pulled in the opposite direction. A coupling mechanism (30) is arranged on the mobile stair (14) that is configured to couple the transport rack (16) to the mobile stair (14) to pull the mobile stair (14) from the retracted into the extended position and to decouple the transport rack (16) from the mobile stair (14) when the transport rack (16) is moved from the die cutting machine (12) beyond the extended position of the mobile stair (14). An assembly with a die cutting machine has a transport rack (16) separate from the die cutting machine (12) that is configured to be pushed against the die cutting machine (12) and removed therefrom, having a counterpart portion for engaging with the coupling mechanism (30).

摘要： A ladder set for rescue vehicles, including a base mounted on a vehicle, an end part and connecting parts disposed therebetween. A traction device is mounted for an extension cable and a roller arrangement for guiding the cable. Roller pairs are mounted on connecting parts, of which each include a front roller and a rear roller. A deflecting roller is located on the end of base part pointing in the direction of extension, via which extension cable is guided in the direction of the traction device. Extension cable is secured to end part by its end opposite traction device and is guided from fixation point to deflecting roller then via roller pairs of connecting parts in their connecting order, in such a way that extension cable first passes the first and then the rear rollers of a roller pair.

摘要： A system is provided for safe access to a roof through an opening in a roof of a structure having a fixed ladder leading upward to the opening. The system includes a mechanism to drive a set of pushrods to raise a hatch covering the opening. The system may include a section of ladder secured to the underside of the hatch. The system may have an extendable ladder driven by the drive mechanism to slide along the fixed ladder and extend through the opening in the roof when the hatch is raised. The system may include a safety pole driven by the drive mechanism to extend through the opening in the roof when the hatch is raised. The system allows someone who needs to access the roof for inspection or maintenance to safely open the hatch, climb up through the opening in the roof, and safely step onto the roof.

摘要： A buffer guiding structure for an extension tube comprises an inner tube, an outer tube, and a buffer member. The inner tube is slidably sleeved into the outer tube. The buffer member is provided at an end surface of one end of the inner tube. An edge of the buffer member engages with an outer edge of the inner tube and abuts against an inner wall of the outer tube, such that when the inner tube extends outwardly, the buffer member is scrolled downwards to reduce a friction force, and when the inner tube retracts inwardly, the buffer member remains slidably abutting against the inner wall of the outer tube, thereby realizing buffer function. The buffer guiding structure for an extension tube has a simple structure and good buffing performance, and can protect hands from being clamped.

摘要： A portable step device is disclosed herein. The portable step device includes a step support surface with a top-side, the step support surface further having a surface-covering affixed to the top-side. The device also features a support rod having a length, a step-end, a base-end, a front-side and a back-side, where the support rod is fixed to the bottom-side of the step support surface and configured to elevate the step support surface away from a terrain. In addition, the device includes a base support surface having a support-rod side and a ground-side to provide stability for bracing the support rod and the step support surface on the terrain.

摘要： A vehicle access system and method with retractable access means, e.g., ladder or stairs and a retracting mechanism therefor. Force applied to the access means is sufficient to retract the access means from a fully deployed position to a partially retracted position but not sufficient to not be physically resisted by a user during at least part of the retraction. With the access means in a fully retracted position, force exerted on the retracted access means can be sufficient to hold the access means in a retracted position without the need for auxiliary restraining means.
摘要翻译： 一种具有可伸缩的通道装置的车辆接入系统和方法，例如梯子或楼梯及其回缩机构。 施加到进入装置的力足以将进入装置从完全展开位置缩回到部分缩回位置，但不足以在至少部分缩回期间不被使用者物理抵抗。 当进入装置处于完全缩回位置时，施加在缩回的进入装置上的力足以将进入装置保持在缩回位置，而不需要辅助限制装置。
