Spring, extension spring are oppositely arranged with reeling rope, and be respectively used to lifting arm outwardly opens action and inside closing action；Specifically
Be to reel rope to pull lifting arm after steel wire rope is pulled up upwards along outer support frame, lifting arm is inwardly collapsed support in track
Plate bottom, when steel wire rope loosens downwards, extension spring pulls lifting arm to outwardly open, and deviates from from track plates bottom；
Further, buffer spring is also arranged with a steel cord, and buffer spring top is provided with upper end cap, and upper end cap is fixed
On outer support frame top, for limiting the top offset of buffer spring, latch bracket is provided with buffer spring bottom, latch bracket is locked at
On steel wire rope, for limiting the bottom offset of buffer spring；The setting of buffer spring can be reduced during lifting to lifting component
Instantaneous stretching power, improve the general safety durability of hook assembly；
Further, it is L-shaped in lifting arm, it is provided with cushion pad in the lifting end of lifting arm；
Further, cushion pad is rubber blanket, is removably arranged on the lifting end of lifting arm；
Further, bearing pin is additionally provided with outer support frame, bearing pin is arranged on the position reeled between rope and steel wire rope, pin
Axle is played a supporting role to reeling rope, effectively avoids reeling the Caton phenomenon of lifting arm in closing action；
Relative to prior art, modified track plates lifting part of the present invention has the advantage that：
Modified track plates lifting part of the present invention is reasonable in design, lifts by crane process safety, is adjusted manually without worker
Whole suspension hook, automatically opening up and reeling automatically for suspension hook can be realized, it is securely and reliably, easy to use, improve lifting efficiency.
