Hand Mechanical are instruments suitable for lifting directly, without using the lever principle, bell-shaped manhole covers for sluice gates, lids of limited weight (less than 15/20 kg).
Hand Mechanical are available as a Complete Set or in single versions: GR1 GR21 GR3 GR5 GR6 GR7
The removal of covers from manholes, even those of limited weight, can be difficult because they are nailed to the frame. The same Hand Mechanical spanners can be used in combination with the UnBlock-30 manhole cover unlocking device.
