Claims

[Scope of utility model registration request]

A leg member 32, an elevating member 34 supported by the leg member 32 so as to be able to rise and fall, a gas spring 36 for applying elastic force upward to the elevating member 34, and normally brake shoes 60 and 62 that move up and down. The elevating member 34 is pressed into contact with the member 34.
is fixed to the leg member 32 side, and when the downward moving force of the lifting member 34 is transmitted to the brake wheel 0, the pressing force of the brake wheel 0 against the lifting member 34 increases, and the brake Mechanism brake juro 0
a brake release pedal 46 for separating the brake pedal from the elevating member 34, and a transmission force relief mechanism disposed between the brake pedal 46 and the brake mechanism, and the transmission force relief mechanism includes a permanent magnet 98 and a transmission force relief mechanism disposed between the brake pedal 46 and the brake mechanism. When the brake pedal 46 is driven in the direction of the brake release force in a state where the gas in the gas spring 36 is released and the pressing force of the brake pedal 0 against the lifting member 34 is increased, In a device in which the adsorption state between the permanent magnet 98 and the adsorption plate 90 is released so that the brake release motion of the brake arm 46 is not transmitted to the brake mechanism, there is a non-magnetic material between the permanent magnet 98 and the adsorption plate 90. A lifting device characterized in that a magnetic force adjusting plate 115 made of a body is movably provided, and by moving the magnetic force adjusting plate 115, the gap between the permanent magnet 98 and the adsorption plate 90 can be adjusted. Base safety device.
