QY80 Truck Crane uses self-made XZ80
special crane chassis. Full-width driver's cab is
spacious, bright and wide vision, with adjustable
seat for comfortable operation. Air-conditioner is
available for option.
5-section telescopic boom and 2-section folding jib
offer a maximum lifting height of 60m. The jib has
three offset angle of 0o, 15oand 30ofor extension
of operating range.
Main structural parts are made of high-tensile steel.
Main boom is all-round hexagonal profile, providing
optimized cross-section and heavy load lifting capacity.
Two-stage telescopic outriggers give wide extension
and good stability.
Equipped with two independent engines of various power
and functions for the superstructure and carrier,
energy distribution more reasonable, not only having
excellent travel performance but also meeting the
need of the crane lifting operation.
Ergonomically designed operator's cab conforms to
ISO standard, spacious and bright, feels tireless
even work for a long time.
Hydraulic pilot control system implements all the
operation precisely with soft moving joystick controls.
New type LCD monitor is used for clear display of

controls, improved safety for operation.
Hydraulic system adopts high-pressure variable displacement
system with multi-pump and multi-circuit, and controlled
by constant power. Hydraulic valve block is designed
in integrated module and fitted with imported joints,
features little loss of energy, less heat, high work
efficiency and energy-saving.
Swing gear has controlled free swing mechanism with
constant-closed brake and fitted with a buffer valve,
realize smooth fine motion control.
Perfect safety protection devices of mechanic-electric-hydraulic
logical control, equipped with automatic load moment
limiter (LML), over-wind and over-release cut-out
device, etc., greatly improved safety for crane operation.
Excellent travel performance: powerful engine, imported
automatic torque converter, dual-circuit hydraulic
powered steering and dual-circuit air brake system,
all these enable the crane to drive safely, quickly
