A special switch is arranged on a top layer or a bottom layer, and a single elevator box or double elevator boxes are arched to automatically stop. Two rods of the switch are respectively connected with two open pull wires which are started by a button with small power, and a middle stop wire is additionally arranged on multiple layers and is pulled to stop by each middle stop wheel switch. Each layer is provided with a change-over switch and is matched at a corresponding position to control a calling circuit of the layer; an uplink circuit is arranged below the idler wheels of the elevator car; a downlink circuit is arranged above the idler wheels of the elevator car; each switch is turned off when reaching the layer and turned on when leaving the layer; the elevator box is provided with a window which can be directly pressed to each layer, and the elevator box automatically changes a button circuit and an arch blocking switch. Power-off disturbance prevention is adopted, and a circuit is switched on after being switched off along with starting of an elevator. The tail end of the reversing stroke is provided with an offside stop switch, a lever is matched with overweight power-off alarm, each door is opened through a series circuit door and closed through a closed door, and a non-bearing lossless steel rope is additionally arranged to prevent falling. Therefore, the absolutely safe passenger elevator is formed.

    一种配装载人载货电梯,在顶层或底层配有特制开关,以单梯箱或双梯箱两面拱到自停。开关两杆分别接两根开的拉线,由按钮小电力开启,多层另加一根中停线,以各中停挨轮开关拉停。由随梯箱而行的滚轮等自动控制,各层配有转换开关,配在相应位置控制本层呼叫电路,上行电路在梯箱滚轮下面,下行电路在梯箱滚轮上面,各开关分别到本层关,离开本层开,每层一个按钮朝外为呼叫,去其它各层按钮朝梯箱,梯箱设窗可直按去到各层,由梯箱自行改变按钮电路,拱挡所到开关。采用断电防扰,随电梯开启切断再开电路。倒顺行程末端设越位必停开关,以杠杆配超重断电报警,各门以串联电路门开而关门关并开,加设不担力无损纲绳防堕。使它形成绝对安全载人电梯。
