4.1 Mode of manual hold
4.1.1
Operation mode
When the operator holds the sliding handle, the operation mode of the handle display
switches from the “locking mode” to the “mode of manual hold”. The operator can control the
system up and down movement through sliding handle. The sliding handle has an intermediate
zero position. The farther the operator moves the slide handle from the neutral zero, the faster the
equipment can run up and down.
4.1.2
Infrared sensor
Intelligence Aided Lifting Equipment is provided with infrared sensor (Fig. 4 1). When the
sensor does not detect the operator, the system is in the “lock mode” and the operator cannot move
the system up or down through the sliding handle control system. When the sensor detects the
operator, the system is in the “mode of manual hold” and the operator can move the system up or
down through the sliding handle control system. The system has a manual timeout value setting,
when the sensor detects the operator, but the operator does not operate the sliding handle for a
time longer than the set value, the operator cannot control the system to go up and down at this
time, and the operator needs to leave and re-hold the sliding handle.

Adjust the maximum operating speed in mode of manual hold
In the mode of manual hold, the maximum operating speed is divided into 10 levels, and the
