The BJ5251JSQY6DPS-01 is a factory-integrated 6x4 Auman crane truck running a Yuchai YCS0270-60 270 hp engine and a Fast 9-speed gearbox with flanged power take-off, on 5.5 t front and 10 t + 10 t tandem rear axles, a 300 mm triple-layer straight-through frame and 11.00R20 wire-belt tyres over a 5,850 + 1,350 mm wheelbase. It measures 12,000 x 2,550 x 3,895 mm with an 8,300 x 2,450 x 550 mm cargo box, and mounts an XCMG G-series 12-tonne 5-section boom crane with an optional single-chamber hydraulic rear outrigger. The package is homologated for Beijing registration.

The Chengli Changwei 10-tonne five-section crane allows the second boom section to extend singly or in combination, with an 18 m working radius and a 20 m lift height, dual-section compound front outriggers and a single-chamber hydraulic rear outrigger, all operated from the deck.

The 14 m3 tank is fabricated in 4 mm high-strength carbon steel with galvanised piping, and a 30 kW body motor drives a Yifeng 50-110 low-pressure pump rated 50 m3/h at 110 m head. Standard equipment covers 24 m cross spray, 14 m rear sprinkling and a 30 m water cannon.

The 14 m3 tank is fabricated from standard Q235 carbon steel with automatic welding and is served by a high-power dedicated pump that self-primes and self-discharges. Front spray, rear sprinkling, side spray, a rear working platform and a water monitor are fitted as standard.

The three-level deck measures about 9.2 m overall (main deck about 5.15 m plus 2.2 m and 1.85 m sections) and 2.55 m wide in 6 mm chequered plate, built from 100 x 100 mm Q355 square tube. It is designed to carry excavators and heavy equipment and can be paired with a Dalishen 10-tonne five-section crane.

The Aumark Zhilan high-end cab is 2,100 mm wide and fitted with a multi-function steering wheel, cruise control and Bluetooth telephone. A rotary electronic selector drives the 120 kWh electric driveline on a 3,800 mm wheelbase for blue-plate heavy-duty recovery work.

The new-process three-section deck measures about 10.3 m overall (main deck about 6.3 m plus 2.2 m and 1.9 m sections) and 2.55 m wide in 6 mm chequered plate, with 3 mm high-strength perforated plate optional. It is designed specifically for carrying excavators and heavy equipment, with a 6-tonne winch and an 8 mm seamless-steel cylinder protection tube.

The integral hydraulic flip deck runs on a full-width hinge shaft with a new arc-section gantry and a sunken deck, in 6 mm chequered plate with 10 mm high-strength folded edge rails drilled for rope hooks. A 120 mm main cylinder, 110 mm lift cylinder and 95 mm tail-flip cylinder power the deck, which sits on 10 mm slide rails with dense egg-crate bracing and twin sub-frames.

The 10-tonne one-to-two body uses twin-side linkage operation and a sunken-deck process, with an 8-tonne hydraulic winch and a 10-tonne three-section rear towing arm. The deck measures 7.55 m including the 1.3 m hydraulic flip tail board, 2.55 m wide in 8 mm chequered plate, on twin longitudinal and transverse ring-stiffened cross members.

The CATL 140 kWh pack is liquid-cooled and liquid-heated and carries an 8-year or 600,000 km warranty; dual-gun 2C charging takes the pack from 20 % to 100 % in 18 minutes. The 3-tonne deck runs high-strength stamped plate, 5.6 m long and 2.3 or 2.55 m wide, on uprated main and lift cylinders with a low-angle design that keeps the deck close to the ground.

The chassis runs a 100 kW motor on a CATL LFP battery rated 55 kWh for a 220 km range. The compactor body is driven by a 20 kW motor drawing 15 kWh per hour and can be replenished from a 120 kW charger in about half an hour.

The arc-section body is built from high-grade carbon steel with 3 mm sides and a 4 mm floor, plumbed with a Zhongmei multi-way valve, Jiangsu cylinders and a Wanyue oil pump with a back-pressure valve. CAN bus control with a remote handset works a rear tipper frame for 120 / 240 L bins.
