Times are indicative and referring to the following operating conditions:
- unloaded crane operated with a single control lever
- oil flow rate recommended for NO RDC crane
- ISO VG 46 oil at a temperature of 50°C
MAX. ALLOWABLE SINK RATE FOR THE LOAD
The sink rate is the uncontrolled descent of the load in a given time interval due to internal leakage
of hydraulic components. The table below shows the maximum permitted descent of the rated load,
at the max. hydraulic outreach and in the given time interval.
