XCMG QAY200 All-Terrain Crane

Overview

The XCMG QAY200 is a 200-ton all-terrain crane combining road-mobile six-axle carrier technology with high lifting performance. It is designed for demanding projects where the crane must travel between sites and then deliver precise heavy lifts — power-plant construction, wind-farm erection, petrochemical maintenance, bridge work and large industrial installations.

The carrier uses a Daimler V8 engine, ZF transmission, KESSLER axles and full hydro-pneumatic suspension with crab-steering capability. The superstructure is driven by a Volvo upper engine and features a six-section U-shape main boom, lattice jib combinations and 65 t of combined counterweight.

Carrier / Chassis

• Frame: XCMG-designed anti-torsion box-section frame made of high-strength steel with a full covered walkway.
• Outriggers: four H-shaped outriggers with two-stage horizontal and vertical hydraulic extension, one-way valves and two-way hydraulic locks on vertical cylinders.
• Carrier engine: Daimler OM502LA.III/3 V8, water-cooled electronically controlled diesel, rated 390 kW @ 1,800 rpm, maximum torque 2,400 N·m @ 1,200 rpm; fuel tank 400 L.
• Transmission: imported ZF electro-pneumatic transmission with 16 forward and 2 reverse gears and retarder braking.
• Transfer case: KESSLER mechanical transfer case with emergency steering oil pump.
• Axles: six KESSLER high-strength axles with pneumatically controlled drum brakes.
• Suspension: full hydro-pneumatic suspension with automatic leveling, suspension lifting and elastic/rigid mode switching.
• Steering: mechanical plus hydraulic-power steering with crab-mode capability by lifting axles 3 and 4.
• Brakes: dual-circuit air service brakes on all wheels, spring-energy parking brake, engine exhaust and retarder braking.
• Operator cab: full-width steel cab with suspension mounting, height-adjustable air-floating driver seat, folding double co-driver seat/bunk, electric-heated mirrors and climate control.

Superstructure

• Upper engine: Volvo TAD720VE in-line six-cylinder EFI diesel, rated 162 kW @ 2,100 rpm, maximum torque 854 N·m @ 1,400 rpm; optional Deutz (Dalian) BF6M1013ECP engine rated 173 kW @ 2,100 rpm.
• Hydraulic system: variable pumps driven by the upper engine for hoisting, luffing and telescoping; closed-circuit pump for slewing; large-bore valves matched with variable piston pumps for smooth starts and stops; air-cooled oil cooler.
• Operation: electric-proportional pilot control with PLC integrated intelligent control; all crane movements are operated from two joysticks with stepless speed regulation.
• Winches: main and auxiliary winches use grooved drums, planetary reducers and constant-closed brakes with balance valves; imported wire rope provides high-speed light-load and low-speed heavy-load operation.
• Slewing: three-row roller external-gearing slewing ring with double slewing mechanisms for 360° continuous rotation, power or free slew and stepless regulation.

Boom and Jib

Configuration	Length
Main boom (6-section U-shape)	13.8–61 m
Lattice/box jib (2 sections, 0°/15°/30°)	11.55–20 m
With 2-section lattice extension	Up to 28 m / 36 m

The single-cylinder pinning telescoping system allows multiple boom-length combinations, and a single-top pulley is available for single-line work with the same rated performance as the 11.55 m jib at 0° offset.

Counterweights

Working mode	Total counterweight	Combination
Mode 1	65 t	A + B×2 + C + D×2
Mode 2	42 t	A + B×2 + C
Mode 3	32 t	A + B + C
Mode 4	22 t	A + C

Counterweight blocks: A = 12.5 t (3050×2254×505 mm), B = 10 t (3050×2254×239 mm), C = 9.5 t (3050×2254×223 mm), D = 11.5 t (1780×1490×983 mm).

Working Speeds

Function	Value
Winch 1 (single line, 4th layer)	0–120 m/min, max. pull 148 kN, rope 26 mm / 280 m
Winch 2 (single line, 4th layer)	0–110 m/min, max. pull 122 kN, rope 26 mm / 210 m
Slewing	360°, 0–1.9 r/min
Boom elevation	−1° to 82° in approx. 60 s
Boom extension	13.8 m to 61 m in approx. 550 s

Hooks

Hook	Lines	Deadweight	Type
200 t	16	2,400 kg	Double hook
130 t	12	1,600 kg	Double hook
65 t	6	1,000 kg	Single hook
30 t	3	500 kg	Single hook

Safety Features

Hydraulic counterbalance valves, relief valves and double-way locks; load moment indicator with audible and visual overload warning, overload memory (black box) and fault self-diagnosis; anti-two-block and lowering limiters; anemometer; 24 V electrical system with two series battery packs.

Applications

Power-plant and substation construction, wind-energy installation and maintenance, petrochemical plant erection, bridge and infrastructure lifting, steel-structure installation and heavy industrial component handling.
