The invention discloses a shear fork lifter suitable for aloft work. The shear fork lifter comprises a base, a shear fork lifting arm, a hydraulic cylinder, a lifting platform, a foldable extension ladder and a height sensor, wherein the shear fork lifting arm is arranged above the base, the lifting platform is arranged above the shear fork lifting arm, the hydraulic cylinder is arranged on the shear fork lifting arm, the foldable extension ladder is arranged on the side edge of the lifting platform, and the height sensor is arranged on the lower surface of the lifting platform. In this way, according to the shear fork lifter suitable for aloft work, the safety height is set in a control device in advance, when the operation height of the lifting platform is larger than the safety height,the height sensor transmits a signal to the control device, and the control device controls an alarm device to give an alarm; and meanwhile, the foldable extension ladder is arranged on one side faceof the lifting platform, and therefore workers can conveniently go down when the lifter breaks down and stays aloft through the foldable extension ladder.

    本发明公开了一种适用于高空作业的剪叉升降机,包括:底座、剪叉升降臂、液压缸、升降平台、可折叠式伸缩梯以及高度传感器,所述剪叉升降臂设置在底座上方,所述升降平台设置在剪叉升降臂上方,所述液压缸设置在剪叉升降臂上,所述可折叠式伸缩梯设置在升降平台的侧边上,所述高度传感器设置在升降平台的下表面。通过上述方式,本发明提高的适用于高空作业的剪叉升降机,通过预先在控制装置中设置好安全高度,当升降平台的作业高度高于安全高度时,高度传感器将信号传递给控制装置,控制装置再控制报警器报警,同时在升降平台的一侧面设置可折叠式伸缩梯,可折叠式伸缩梯可方便工作人员在升降机出现故障停留高空时方便下来。
