Snorkel AB48HSRT-sn4611+ - Manual (Page 7)

The UpRight AB48HSRT is of the parallel linkage vertical boom design, mounted on
an all terrain platform. The unique, yet very simple boom configuration gives the
maximum safety and control ability combined with a robust construction to
withstand a heavy working environment
The AB48HSRT machine is designed for two man capacity (215kg (474lb.)S.W.L.).
The machine incorporates a bottom boom with tie-rod, a short vertical boom and a
top boom with a telescope section. The AB48HSRT also has an independent
hydraulically operated flick-out boom and rotating cage for extra manoeuvrability.
The hydraulic system is of a failsafe design throughout, with built in hydraulic lock
valves on all of the rams as a precaution against hose failure. The machine is
controlled by means of proportional manual controls of the ‘direct hand’ lever
operating type. These valves are located at both the base and in the cage, as
standard.
Electrically operated emergency lowering valves are fitted as standard to allow the
machine to be lowered from the base and basket.
The hydraulically operated outriggers are fitted with electronic micro-switches, to
prevent the booms from being raised without the outriggers being extended and
under load. A micro-switch also prevents the hydraulic outriggers being
accidentally retracted while the booms are raised.
