ReliabilitySafe Control SystemSwitch between the operation and
installation modes is more convenient and reliable, and the crane's
functions including electronic level gauge, off-line stop,
emergency electric control, and closed-circuit monitoring ensure
your safety; load moment limiter is free of calibration, which
provides you with a safer operation and costs you less
time.Reliable Function GuaranteeSufficient safety margin in
structural design; the control system runs stably even in extreme
cold / hot weather, high altitude and sandy regions; the key
components like pumps, valves, motors, and reducers of
international well-known brands are reliable and stable; advanced
hydraulic technology, lightning protection, waterproof/dustproof
devices are adopted to ensure the whole machine's stability and
reliability; the crane passed the verification test of the strength
twice higher than that in the industry.High Return & Low
