8 Ton Crawler Spider Crane BJ-800: Tackles Heavy Lifts, Narrow & Rough Terrain

Ever struggled with regular truck cranes on big construction sites, factory overhauls, or large-scale landscaping? They get stuck in narrow alleys, sink in muddy ground, and chicken out on steep slopes. But this 8-ton crawler spider crane BJ-800 fixes all that! 8 tons of lifting power, crawler tracks for any terrain, and it navigates tight spots like a pro. Let’s cut to the chase—here’s why it’s a game-changer:

1. 8-Ton Lifting Power + Precision—No Shaking, No Delays

This crane’s built for steady and fast lifts. Every part goes through multiple strength tests, so hoisting 8-ton loads feels rock-solid. The standard winch with brake uses 4 steel cables, pulling the hook up at 12m/min—hoisting a heavy steel beam to 20m takes less than 2 minutes!The steel cable’s tough too: Φ12mm thick, 80m long, and it won’t snap even at full load. The telescopic boom has 5 sections (5m each), adjustable from 5.5m to 21m, and fully extends in just 54 seconds—perfect for tight schedules. Need a custom boom length? The factory can tweak it for you.Angle adjustment’s snappy too: 0–78° in 13 seconds, so you can hit tight spots like factory corners dead-on. It also spins 360° continuously (38 seconds per full rotation)—no need to move the crane around, saving half the time!

2. Crawler Tracks = No Stuck, No Shaking—Maneuver Like a Boss

Regular cranes sink in soft ground, but the BJ-800? Its 2-section outriggers twist out manually and lock with hydraulic support, extending up to 7000mm (length) × 6700mm (front) × 5070mm (rear). Even on rain-soaked mud, it stays stable lifting at 18m radius.The crawler tracks are the real star: 350mm wide, 52.5mm pitch, 104 sections total. They spread the 8700kg weight evenly, so no sinking in mud or sand. Dual-speed hydraulic motor drives it at up to 2.5km/h (quieter than a truck!) and climbs 25° slopes (36% grade) without a hitch—no need for ramps.Size-wise, it’s a ninja: 6.15m (L) × 1.6m (W) × 2.25m (H). It squeezes through narrow residential lanes, between construction equipment, and into tight factory spaces—way more agile than same-tonnage truck cranes.

3. Tough Engine—Saves Fuel, Starts in -5°C

A crane’s only as good as its engine. The BJ-800 uses a Yunnei 490 diesel—tradesmen know this engine’s a workhorse. It runs full-load all day without breaking a sweat, and you can swap it for other models if needed.Electric start makes life easy: no more heating the engine in winter—it fires up at -5°C. It handles 40°C summer heat too, no overheating. The 8L fuel tank might seem small, but diesel efficiency means it runs half a day on one fill. The 24V 45AH battery keeps the control system going even if the engine’s off.Bonus: It meets China Stage II emissions standards—safe for residential areas or scenic spots, no shutdowns over pollution.

4. Simple, Safe Controls—Add Extras as You Need

Veteran operators love manual controls—boom, outriggers, and travel all adjusted by hand. You get precise control, way more reliable than fully auto for tricky lifts. Working in dangerous spots (high-voltage lines, crowded areas)? Add a remote control and operate from safety.Customize with extras for your job:

• Torque controller: Alerts you if overloaded—prevents crane damage;

• Suspension basket: Turns it into an aerial work platform (no extra scaffolding for wall maintenance or light installation);

• Hydraulic fly jib: Reaches tight corners regular booms can’t—great for lifting parts in equipment gaps.

5. Scenarios Where It Crushes the Competition

• Construction: Hoist girders or transport steel in narrow building gaps—no repeated crane moves;

• Factories: Replace large machine parts or repair production lines—no wall demolition, no production stops;

• Infrastructure: Lift guardrails on hills or install components under bridges—handles rough slopes and mud;

• Landscaping: Move big trees or install giant landscape stones—no sinking in soft soil, precise placement.

Why Pick the BJ-800? 3 Simple Reasons

First, power: 8-ton lift, 18m radius, 21m height—handles most heavy jobs. Second, stability: Crawlers + big outriggers = safe on any terrain. Third, hassle-free: Tough engine, customizable parts, and solid after-sales.Whether you’re a construction boss or equipment renter, the BJ-800 takes on tough jobs others can’t—this is your money-maker!
