12 EMERGENCY DESCENT SYSTEM
As a precaution against possible power failure, the lift is equipped with a battery operated
emergency descent system.
1. The system comprises
- 12 V, 44 Ah
- recharger
- hydraulic unit 12 VDC
2. Servicing the battery
- the system incorporates an automatic battery recharger with short circuit and
overheat protection
‐ output 125 W
‐ charging voltage 13.7–14.7 V
‐ rated current 10 A
3. The hydraulic unit comprises:
- pressure relief valve, set value 16 MPa (160 bar)
- check valve
- direct current motor of 800 W
Start the emergency descent system by depressing the pushbutton (20 on the platform
and 5 on the chassis).
The emergency descent system is operational only when the pushbutton is being
depressed.
Using the emergency descent, retract first the telescope completely, then
lower the boom, and finally, turn the boom.
The emergency descent system can also be used for raising the support outriggers to the
transport position
If the emergency descent system does not operate, try to attract the attention of other
personnel present on the site, so that they can restore the power supply to the lift, or
make its emergency system operational by, for example, changing the battery.
Always check the condition of the battery for the emergency descent system before
putting the lift into operation.
