摘要： A lifting device that can effectively lift a variety of objects and enhance portability. The lifting device provides demountable portability that enables easy adaptation of the invention for objects of varying size. This adaptability provides a universality that minimizes the number of lifting devices need. The demountable nature of the invention also aids in efficient storage. Generally described, the lifting device includes a mast separable into a plurality of sections and a pulley supported by a first section of the mast. A dolly that supports the mast includes one or more transport structures for movably supporting the lifting device. An actuator is mounted on a second section of the mast. A carriage captured on the mast is configured to slide along the mast and directly or indirectly support an object to be lifted. The lifting device also includes a belt with a first end and a second end. The first end attaches to the carriage and the second end attaches to the actuator so that the belt extends over the pulley. The actuator selectively reels the belt in and out when the belt is positioned over the pulley. This causes the carriage to move up and down along the mast. The belt is removable from the pulley. The first section of the mast is removable from the second section of the mast when the belt is removed from the pulley. This provides the lift with demountable portability.

摘要翻译： 提升装置可以有效地提升各种物体，增强便携性。 提升装置提供可拆卸的便携性，使得能够容易地将本发明适用于不同尺寸的物体。 这种适应性提供了使起重设备需要数量最小化的普遍性。 本发明的可拆卸性质还有助于有效的储存。 通常描述，提升装置包括可分离成多个部分的桅杆和由桅杆的第一部分支撑的滑轮。 支撑桅杆的台车包括用于可移动地支撑提升装置的一个或多个运输结构。 致动器安装在桅杆的第二部分上。 在桅杆上捕获的滑架被配置为沿着桅杆滑动并且直接或间接地支撑要被提升的物体。 提升装置还包括具有第一端和第二端的带。 第一端连接到滑架，第二端附接到致动器，使得皮带延伸穿过皮带轮。 当皮带定位在滑轮上方时，致动器选择性地卷绕皮带。 这使得滑架沿着桅杆上下移动。 皮带可从皮带轮拆卸。 当皮带从皮带轮上取下时，桅杆的第一部分可从桅杆的第二部分移除。 这为电梯提供了可拆卸的便携性。
