Heavy Duty Crawler Crane
- Heavy Duty Hydraulic Crawler Crane
Heavy Duty Hydraulic Crawler Crane
The CQUY series is a multi-functional, Heavy Duty Hydraulic Crawler Crane featuring a full-slewing structure and multi-section truss boom configuration. With optional attachments, it delivers versatile operational capabilities, including general lifting, pipe rolling, diesel hammer piling, hydraulic hammer operation, casing oscillator driving, pile driving, deep-excavation clamshell grabbing, dragline operation, and dynamic compaction.
It is widely applicable across various construction sectors, including transportation, chemical engineering, energy, water conservancy, municipal engineering, civil construction, metallurgy and steel industries.

Characteristics and Applications of Lattice Boom Crawler Cranes
Main Characteristics
Strong lifting capacity
Adopting a truss-type lattice boom that is lightweight, high in rigidity and small in wind-receiving area,
it is suitable for heavy-duty, high-height and long-radius lifting.
-
Excellent operation stability
The crawlers have a large ground contact area and low ground pressure,
allowing operation without outriggers. The whole machine has a low center of gravity and strong anti-overturning capacity.
-
Capable of traveling with load
It can move at low speed while lifting,
which is especially suitable for equipment positioning, multi-point hoisting and continuous operation.
-
Strong terrain adaptability
Capable of traveling and operating on complex road conditions
such as muddy, soft sites, construction access roads and slopes, with much better passability than truck cranes.
-
Flexible working condition combinations
Can be equipped with main boom, fixed jib, luffing jib, superlift device, etc.,
to meet lifting requirements of different heights, radii and weights.
-
Convenient disassembly, assembly and transportation
The boom, crawlers, counterweights and upper structure can be split modularly,
facilitating highway transportation and relocation between different sites.
Main Application Fields
-
Wind power engineering
Hoisting of wind turbine nacelles, hubs and blades;
it is the main equipment for onshore high-megawatt wind turbines.
-
Petrochemical & coal chemical industry
Hoisting of large towers, reactors, storage tanks, torches and steel structures.
-
Power construction
Hoisting of thermal power boiler steel frames, generator stators and heavy equipment for nuclear power.
-
Bridge engineering
Hoisting of steel box girders, steel truss girders, bent caps and integral segments.
-
High-rise buildings & steel structure engineering
Installation of giant steel columns, trusses, tower crane erection/dismantling and heavy components.
-
Shipbuilding & port engineering
Hoisting of hull sections, port equipment and heavy wharf components.
-
Mining & metallurgy
Positioning of heavy equipment such as large mills, converters and rolling mills.
