Steadily, driving lifting velocity is fast again.
(2) connected firmly between one end of girder and fixed end beam by two bearing pins, the other end of girder and movable end carriage it
Between connected by single hinge, formed one degree of freedom, because 3 points determine a plane, also may be used even if girder out-of-flatness
To ensure that four wheels are in approximately the same plane all the time, whole vehicle body is steady, easily installs and safeguards.
(3) sensor of shearing force can be sensed by being set on fixed pulley axis, alarm signal is sent when electric block is overweight
Number, more than amount load 10 when can automatically cut off riser circuit prevent electric block is from raising, prevent overload
And trigger accident.
(4) by setting over speed protection on reel, when lifting motor is abnormal, reel emergency brake can be reduced
Personnel's property loss.
