摘要： An invalid hoist includes a lifting arm, an actuator between the lifting arm and a mast, the lifting arm being pivotably connected to the upper end of the mast at a position intermediate its ends and the actuator being connected to the lifting arm on the side of the pivotable connection between the lifting arm and the mast remote from said one end of the lifting arm, and a connecting link pivotably connected between one end of the actuator and the lifting arm (or mast). The connecting link is connected between the actuator and the lifting arm (or mast) such that an auxiliary link incorporating a load cell can be additionally and removably connected between the actuator and the lifting arm (or mast) and such that any load applied to the lifting arm is transmitted entirely through the auxiliary link.

摘要： A chassis comprises two legs extending in parallel spaced apart relationship and a cross member connecting the two legs together. The cross member comprises first, second and third tubular members. The second member is telescopically extendible and retractable in the first member and the third member is telescopically extendible and retractable in the second member. A linear actuator is provided for extending and retracting the second and third members in opposite directions relative to the first member.
摘要翻译：底盘包括两个以平行间隔开的关系延伸的腿和将两个腿连接在一起的横向构件。横向构件包括第一，第二和第三管状构件。第二构件在第一构件中可伸缩地伸缩并且第三构件在第二构件中可伸缩地伸缩。线性致动器被提供用于相对于第一构件在相反方向上延伸和缩回第二和第三构件。

摘要： An invalid hoist comprises a mast, a lifting arm which can be raised and lowered by telescopically extending and retracting the mast and/or by raising and lowering a carriage, which may support the lifting arm, relative to the mast, and a load cell on the lifting arm for providing a signal representative of the weight of a person being lifted. The lifting arm is connected to the mast or the carriage by an arrangement which allows the lifting arm to be displaced angularly in a vertical plane against a spring force in order to maintain the load cell in a constant orientation as a vertical load is applied to the lifting arm.
