双联齿轮泵34输入轴通过联轴器Ⅱ31与高速轴28联接，双联齿轮泵34进油口连接油箱33，双联齿轮泵34前泵出油口通过润滑油进油管路40连接左制动器、离合器和右制动器的润滑油入口，润滑油进油管路40设有溢流阀Ⅰ30，溢流阀Ⅰ30连接油箱33，通过双联齿轮泵34分别向离合器、左制动器、和右制动器的摩擦片组添加润滑油，通过溢流阀Ⅰ30调节油压。
双联齿轮泵34后泵出油口连接两位四通电磁换向阀32的进油口，并且在双联齿轮泵34后泵出油口连接两位四通电磁换向阀32的进油口的管路上设有溢流阀Ⅱ35，溢流阀Ⅱ35连接油箱33。两位四通电磁换向阀32的工作油口一通过左制动器压力油管路41连接左制动器油缸19，两位四通电磁换向阀32的工作油口二通过离合器压力油管路42连接离合器油缸10，两位四通电磁换向阀32的回油口连接油箱33。
提升机正常工作时，电机25通过联轴器Ⅰ26带动高速轴28，再通过联轴器Ⅱ31带动双联齿轮泵34，两位四通电磁换向阀32得电，两位四通电磁换向阀32的进油口与工作油口二导通、工作油口一与回油口导通，双联齿轮泵34后泵出油口输出的压力油通过离合器压力油管路42进入离合器油缸10，油的压力通过溢流阀Ⅱ35调节，压力油推动离合器活塞11伸出，离合器活塞11带动离合器内摩擦片组13与离合器外摩擦片组14贴合，使离合器接合，右制动器外摩擦片组38与右制动器内摩擦片组37分离，右制动器弹簧8处于压缩状态，此时左制动器、右制动器均处于非制动状态；双联齿轮泵34前泵输出的压力油通过润滑油进油管路40进入离合器、左制动器、右制动器的润滑油入口，对离合器、左制动器、右制动器的摩擦片组进行润滑冷却；高速轴28带动齿轮Ⅰ27，再带动齿轮Ⅱ18，中心轴1随之转动，从而带动中心齿轮4转动，同时高速轴28通过齿轮Ⅲ29、齿轮Ⅳ16和离合器带动行星架7转动，调定好齿轮Ⅲ29、齿轮Ⅳ16的传动比，即可控制行星架7的转向，从而控制内齿轮5即卷筒3的转速。
在突然断电且外加制动器失效的情况下，物料通过钢丝绳带动卷筒3反转，物料下落，此时两位四通电磁换向阀32失电，两位四通电磁换向阀32的进油口与工作油口一导通、工作油口二与回油口导通，离合器油缸10泄压，离合器活塞11回缩，使离合器分离，右制动器弹簧8推动右制动器外摩擦片组38、右制动器内摩擦片组37贴合，右制动器处于制动状态，行星架7停止转动，行星轮系转化成定轴轮系；此时虽然卷筒反转，但高速轴转向不变；双联齿轮泵34在卷筒3及定轴轮系的带动下继续工作，双联齿轮泵34后泵出油口输出的压力油通过左制动器压力油管路41进入左制动器油缸19，压力油推动左制动器活塞20伸出，左制动器活塞20推动左制动器外摩擦片组22和左制动器内摩擦片组23贴合，左制动器弹簧21压缩，左制动器处于制动状态，实现中心 轴1的制动，从而实现卷筒3制动。
卷筒3速度接近零时，双联齿轮泵34会停止供给压力油，左制动器弹簧21复位并推动左制动器外摩擦片组22和左制动器内摩擦片组23分离，左制动器松开，物料继续下降，则双联齿轮泵34重新开始工作，实现卷筒3减速制动。
上述过程不断重复，实现物料以较低的速度缓慢落地，从而避免了物料从高处以较高的速度直接落地所造成的事故。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
