Traditional mobile cranes simply cannot operate in tight spaces — rooftops, indoor factories, substations, and narrow urban alleys all demand a different kind of lifting solution. That is exactly where the 3-ton six-section boom spider crane from DAXLIFTER excels. Engineered and manufactured by QINGDAO DAXIN MACHINERY CO LTD, this compact crawler crane delivers up to 10.1 meters of working radius and 11 meters of ground-level lifting height, yet folds into a remarkably small footprint of just 3.1 m × 0.95 m — narrow enough to pass through standard doorways and ride any freight elevator.
Equipped with dual diesel-and-electric power, a high-strength manganese-steel six-section boom, and a 360° continuous-rotation turntable, this spider crane combines raw lifting performance with pinpoint precision in the most space-constrained environments on the planet. Whether you are installing rooftop HVAC units, performing substation maintenance, or handling glass curtain walls, the DAXLIFTER 3-ton mini crawler crane is purpose-built to get the job done — safely, efficiently, and affordably.
With an overall width of just 950 mm and a total length of 3,100 mm, the DAXLIFTER 3-ton spider crane is one of the most compact tracked cranes available. It can pass through standard single doorways, fit into tight elevator shafts, and operate in aisles where conventional cranes simply cannot go. Its retractable outriggers shrink to just 950 mm for transport and storage.
Despite its compact footprint, this six-section boom spider crane delivers a rated capacity of up to 3,000 kg at 2 meters and maintains useful lifting performance all the way out to a 10.1-meter working radius. The high-strength manganese-steel boom provides exceptional strength-to-weight ratio, enabling serious lifting from a mini chassis.
The hydraulic telescopic outrigger system with auto-support function deploys and levels the crane in seconds — not minutes. Combined with electric start, one-key outrigger leveling (optional), and remote-controller operation, a two-person crew can set up and begin lifting within moments, dramatically reducing labor costs and downtime on every job site.
Advanced torque-control systems continuously monitor boom length, angle, and load in real time. Automatic alarms and limiting functions engage before any overload condition develops. The forged self-locking hook with anti-detach design ensures the load stays secure throughout the lift cycle, giving operators total peace of mind.
From rooftop HVAC installations to indoor factory maintenance, from substation electrical work to glass curtain wall fitting — this compact boom crane adapts to virtually any confined-space lifting challenge. Optional attachments such as a rotating basket, auxiliary jib, and fly jib extend its versatility even further.
The Youpu diesel engine paired with 380 V electric motor delivers reliable dual-power operation. Fuel consumption stays low thanks to the small-displacement, high-torque engine design. National Standard Level II emissions compliance means you meet environmental regulations without sacrificing performance — all at a competitive price point.

Key Highlights:
The DAXLIFTER 3-ton spider crane supports a range of factory-installed optional attachments and configurations to extend its capabilities across diverse lifting scenarios.
Dual-function attachment enabling both material lifting and aerial personnel work. Ideal for installation, maintenance, and inspection tasks at height without requiring a separate aerial work platform.
Extends the working radius and lifting height beyond the standard six-section boom limits. Essential for ultra-long or ultra-high lifting applications where the main boom alone cannot reach.
Similar to the auxiliary jib, the fly jib provides additional reach for specialized applications. Perfect for bridge construction, sign installation, and other scenarios requiring extended horizontal or vertical reach.
Enables long-distance wireless control of all crane functions with smooth, proportional load movement. The operator can position themselves for optimal visibility, making it ideal for precision mechanical installation and confined-space work.
Real-time digital display of boom length, boom angle, and actual load. Automatic alarm and limiting functions activate before overload conditions develop, providing an additional layer of intelligent safety protection.
Wireless remote system with long-range, multi-channel, anti-interference communication. A single button press automatically extends, retracts, and levels all outriggers — reducing setup time to seconds and eliminating manual leveling errors.
Hook Specification: High-strength forged hook with self-locking anti-detach mechanism. Wear-resistant and durable construction ensures long service life under demanding conditions.
The DAXLIFTER 3-ton compact crawler crane is engineered for versatility. Below are six of the most common application scenarios where this mini crawler crane proves its value every day.
Lift chillers, cooling towers, and air-handling units onto building rooftops where traditional cranes cannot access. The spider crane's compact width allows it to ride freight elevators or be winched to the roof, then deploy outriggers and begin lifting immediately.
Perform transformer replacement, busbar installation, and switchgear maintenance inside live or confined substations. Rubber tracks leave no damage on finished floors, and electric-power mode enables zero-emission indoor operation.
Move heavy machinery, presses, and production-line equipment within factories and warehouses. The narrow 950 mm body width navigates between production lines and through standard industrial doorways with ease.
Position large glass panels on high-rise facades with precision. The 360° continuous rotation and variable-speed hydraulic controls allow millimeter-accurate placement, while the optional rotating basket doubles as a personnel work platform.
Work inside bridge box girders, tunnel segments, and other confined civil-engineering environments. The underground hoisting capability (up to 40 m depth on single-rope) makes it invaluable for shaft-sinking and tunnel-boring support operations.
Rapidly deploy lighting rigs, sound equipment, and stage structures at concert venues, exhibition halls, and outdoor event sites. Quick setup and teardown keep production schedules on track.
Q: What is a spider crane?
A: A spider crane is a compact, tracked lifting machine with telescopic outriggers that resemble spider legs. Also known as a mini crawler crane or compact boom crane, it is designed for lifting in confined spaces where traditional mobile cranes cannot operate.
Q: How much weight can a 3-ton spider crane lift?
A: The DAXLIFTER 3-ton spider crane can lift up to 3,000 kg at a 2-meter radius. At its maximum working radius of 10.1 meters, it can still handle 100 kg. Rated capacity varies by boom angle and radius — see the working performance chart above.
Q: What is the maximum working radius of this spider crane?
A: The maximum working radius is 10.1 meters at 0.4 tons (400 kg). The six-section telescopic boom provides precise reach adjustment across the full range.
Q: Can the spider crane work indoors?
A: Yes. With a body width of just 950 mm, the crane can pass through standard doorways and operate inside buildings. Switch to electric power mode for zero-emission indoor operation.
Q: How does it fit through standard doorways?
A: The overall width is only 950 mm (under 1 meter), and the outriggers can be fully retracted to maintain this narrow profile during transport. Most standard industrial and commercial doorways are 900 mm to 1,200 mm wide.
Q: What power options are available?
A: The standard configuration includes dual power: a Youpu diesel engine (2V80/F195) and a 380 V electric motor. The diesel engine provides mobile outdoor operation, while the electric motor enables quiet, emission-free indoor use. Both systems can be selected via a simple power switch.
Q: How fast can it be set up?
A: With the optional one-key outrigger leveling system, setup takes less than one minute. The hydraulic outriggers auto-extend and auto-level at the push of a button. Even without the optional system, hydraulic deployment is significantly faster than manual outrigger setups.
Q: Is it safe on uneven terrain?
A: Yes. The hydraulic auto-support outrigger system automatically compensates for ground irregularities. The rubber track undercarriage provides stable traction on slopes up to 20° (36% grade). The intelligent torque control system continuously monitors load conditions and prevents unsafe operation.
Q: What maintenance is required?
A: Regular maintenance includes hydraulic oil checks and changes, wire rope inspection, track tension adjustment, and engine oil/service per the Youpu engine schedule. The electric-start system and sealed hydraulic components minimize routine service requirements.
Q: How does a spider crane compare to a traditional mobile crane?
A: A spider crane offers a dramatically smaller footprint (950 mm vs. 2,500+ mm width), can operate indoors, requires far less setup space, and can be transported via freight elevator. While a traditional mobile crane offers higher capacity at longer reach, the spider crane excels in confined-space applications where no other crane can go.
