摘要： A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

摘要： A portable lift is provided. The portable lift includes a top frame assembly, a carriage frame, a base frame, and a hoist mechanism. The top frame assembly is secures top ends of a pair of stringers together. The base frame assembly secures bottom ends of the pair of stringers together forming the portable lift frame. The carriage frame includes a plurality of wheel assemblies each having a plurality of wheels. The plurality of wheels releasably retain to and slidably engage with a stringer of the pair of stringers. The hoist mechanism includes a motor, a spool rotatable by the motor, a pulley secured to the top frame assembly, and a hoist cable wrapped around the spool and running from the spool through the pulley and secured to the carriage frame.

摘要： An apparatus for lifting planar objects which includes an extendable rectilinear elongated frame formed of at least two spaced U-beams, each U-beam defining a longitudinal runway and having an elongated area removed from a forward face below a midpoint of the frame. The removed elongated area defines an entranceway to the longitudinal runway. The entranceway is dimensioned to receive the planar object for placement on a transport carriage while maintaining a top portion of the planar object within the longitudinal runway. The carriage is configured to laterally span the two spaced U-beams such that a portion of the carriage and a portion of the planar object are confined within each interior longitudinal runway at least during transport. A skid is perpendicularly joined to a forward face of the carriage at about its bottom edge. The skid is configured to support the planar object during placement and lifting. A pull cable is affixed at one end to the carriage at about a midpoint of a lateral dimension and in proximity to a top edge of the carriage. A first cross member is laterally joined to a top of the frame which includes a pulley aligned such that the pull cable when in communication with the pulley and affixed to the carriage are aligned along a common longitudinal centerline between the two spaced U-beams. A second cross member is likewise laterally joined to the frame in proximity to the entranceway. A winch is connected to an opposite end of the pull cable and configured to move the carriage and planar object through the longitudinal runways.
摘要翻译： 一种用于提升平面物体的装置，其包括由至少两个间隔开的U形梁形成的可延伸的直线细长框架，每个U形梁限定纵向跑道，并且具有从框架中点下方的前面移除的细长区域。 去除的细长区域限定到纵向跑道的入口。 入口的尺寸被设计成接收用于放置在运输托架上的平面物体，同时将平面物体的顶部部分保持在纵向跑道内。 滑架构造成横向跨越两个间隔的U形梁，使得滑架的一部分和平面物体的一部分至少在运输期间被限制在每个内部纵向跑道内。 滑架在其底部边缘处垂直地连接到滑架的前面。 滑轨被配置为在放置和提升期间支撑平面物体。 拉线在一端附近固定在托架上，大约在侧向尺寸的中点处并且靠近托架顶部边缘。 第一横向构件横向地连接到框架的顶部，其包括滑轮对准，使得当与滑轮连通并固定到滑架的拉索沿着两个间隔开的U形梁之间的公共纵向中心线对齐。 第二横向构件同样在接近入口处横向地连接到框架。 绞盘连接到拉绳的另一端并构造成通过纵向跑道移动滑架和平面物体。

摘要： A vehicle is provided having a lift device comprising: a carrier; a swing arm with one end fixed to a shaft and another end coupled the carrier; and a drive for swinging the swing arm on top of the vehicle. The carrier is lowered from the top of the vehicle at an inclination with the point at which the carrier is attached to the swing arm raised. The swing arm comprises a first arm fixed to the shaft and a second arm mobile along the first arm that is coupled to the carrier. Telescoping means displace the second arm along the first arm when the swing arm swings, so that the carrier is retracted when the swing arm is upright. A support device supports the carrier, and support position displacement means cause it to project horizontally from the top of the vehicle when the carrier is lowered.
