When it comes to indoor construction, urban renovations, and multi-story projects, traditional cranes are simply too bulky to deliver. Contractors frequently face the frustrating challenge of maneuvering heavy equipment through standard doorways or operating inside sensitive environments like shopping malls and museums. Furthermore, their massive weight poses a severe risk to upper-floor structural integrity. Caught between inefficient manual handling and tight project deadlines, the industry has long demanded a smarter alternative. Enter the spider lift crane—the ultimate compact crane designed to revolutionise limited space lifting.
This machine combines the lifting power of a crane with the compact size of a spider lift. It folds down to pass through narrow openings. Four hydraulic outriggers extend for rock-solid stability. The 5-section telescopic boom reaches up to 18 meters—yet the machine weighs only 2700-7200kg. This is the equipment that lets you work where other cranes cannot go.

Small Spider Crane: 6 Advantages That Make It Essential
A small spider crane from YG offers distinct advantages over conventional lifting equipment. Here is what buyers get.
1. Ultra-compact design. The YG-3 folds to just 980mm wide. This fits through standard 36-inch doorways and into passenger elevators. Traditional cranes cannot access these spaces. The machine enters buildings and works on upper floors without disassembly.
2. Superior stability. Four outriggers extend to create a wide support base. Each outrigger adjusts independently for sloping ground. The machine levels itself on uneven surfaces. This stability means you can lift heavy loads without worrying about tipping.
3. 360° continuous rotation. The turntable rotates full circle without stopping. Operators position loads precisely without repositioning the machine. This saves time on complex lifts. The rotation speed of 38-60 seconds per full turn gives you control.
4. Long reach, light weight. The YG-8 lifts 8 tons at close radius and 1 ton at 16.5 meters. Yet the machine weighs only 7.2 tons. This high strength-to-weight ratio lets you work on weight-sensitive floors.
5. Dual power flexibility. Standard equipment includes both a diesel engine and an electric motor. Use the electric motor indoors for zero emissions and quiet operation. Switch to diesel outdoors for long shifts and remote sites.
6. Rubber tracks. The tracked undercarriage provides excellent traction on rough terrain. The rubber material does not damage finished floors. Track ground pressure is low, typically 11.3 psi, which minimizes surface disruption.

Mini Crawler Crane for Sale: 6 Common Applications
A mini crawler crane for sale from YG finds work across many industries. Here are the most common uses.
- Glass installation. High-rise building facades require the precise placement of heavy glass panels. The machine enters the building through standard openings, travels to the correct floor, and lifts panels into place. A contractor in Washington D.C., used a YG-3 for a glass facade project and completed the job in 3 days instead of 5.
- Interior renovations. Shopping malls, hotels, and museums need materials lifted to upper levels. The electric motor runs silently indoors. No noise complaints. No exhaust fumes. The machine works during business hours without disturbing customers.
- Equipment installation. Factories and industrial plants need heavy machinery placed in tight spaces. The machine maneuvers through narrow aisles and positions equipment exactly where needed. A German maintenance company used a YG-5 to replace 5-ton equipment inside a plant, avoiding costly wall demolition.
- Bridge and infrastructure maintenance. Under-bridge work requires equipment that can be positioned safely on slopes and uneven ground. The 36% gradeability handles steep approaches. The outriggers level the machine on angled surfaces.
- Urban construction. City streets have limited space for large cranes. The compact size lets you set up in parking lots, alleyways, and between buildings. No road closures. No traffic disruptions.
- Tree care and landscaping. Arborists lift heavy branches and equipment into trees. The tracked undercarriage works on lawns without damaging grass. The 360° rotation reaches around obstacles.

Tracked Mini Crane: 3 Features That Simplify Operation
A tracked mini crane from YG makes lifting easier for operators. The machine uses several features to reduce complexity.
Remote control option. Operators control the crane from a safe distance. The wireless remote provides precise joystick control over boom extension, luffing, rotation, and hoisting. This is especially useful for glass installation and other delicate work where precision matters.
Manual operation backup. The machine includes manual controls on the machine itself. If the remote control loses signal or the battery dies, operators work from the control panel. No downtime waiting for replacements.
5-section U-shaped boom. The boom extends in five sections, giving you flexibility in reach and height. The U-shaped cross-section provides strength without adding weight. The telescoping time is 20-54 seconds, depending on the model.
30% Labor Cost Savings: A Case of Spider Lift Crane in the Philippines
A Philippine construction company took on a high-rise building renovation in central Philippines in early 2023. The project required hoisting glass panels and stone materials to multiple floors. Passenger elevators had narrow doors that could not fit standard cranes. Traditional lifting meant workers carrying materials up stairs – slow, exhausting, and dangerous.
The company bought a YG-3 electric spider lift crane from us. The machine folded to 980mm wide and entered the elevator without disassembly. The electric motor ran silently on each floor. Zero emissions. Zero noise complaints from residents.
One operator and one ground worker handled all material lifting. The crane lifted materials through floor-to-ceiling windows or open balcony areas. The wireless remote control lets the operator see the placement point clearly.
The results were significant. Renovation time dropped from 10 weeks to 7 weeks – a 30% reduction. Labor costs decreased by two workers per shift. The machine operated daily without any breakdowns. The company purchased two more units for other projects and recommends them to industry peers.
YG Machinery shipped the machine from Zhengzhou with a 12-month warranty. We provided video training for the crew and remote technical support throughout the project. Spare parts arrived from our warehouse within 3 days of the first order.【WhatsApp/WeChat/Phone】+86 183 3715 2861
FAQs About YG Spider Lift Crane
Yes. The electric motor runs silently with zero emissions, making it ideal for indoor decoration, shopping mall renovations, museums, and other environments that require quiet operation.
All YG spider lift cranes have rubber tracks. The tracks provide better traction on grass, slopes, mud, and other complex surfaces. Non-marking rubber also protects finished floors
Consider three factors: lifting weight, working height, and site access dimensions. For indoor use on multiple floors, prioritize models under 1000mm width and over 12m lifting height. We provide free sizing advice.
Yes. The 36% gradeability (25°) lets you work on moderate slopes. The independent outrigger leveling compensates for uneven ground. Do not operate on slopes beyond the rated gradeability.
Yes. All YG spider cranes meet CE safety standards and include overload protection, outrigger deployment interlocks, and abnormality alarms that automatically shut down the machine.
