The small spider crane, also known as a mini tracked crane, is a type of aerial work platform that integrates hydraulic drive, wireless remote control, and tracked mobility. Resembling a spider in appearance, it features extendable outriggers and a compact body, making it ideal for narrow spaces inaccessible to large cranes. YG manufactures mini spider cranes with lifting capacities ranging from 1.5 to 12 tons. The most commonly used models—3-ton, 5-ton, and 8-ton—are widely applied in indoor and outdoor lifting operations, curtain wall construction, municipal engineering, and other fields. If you are looking for an efficient, safe, and customizable tracked mini crane, please feel free to contact us at any time for quotes, configurations, and customization solutions!
3T ＆ 5T ＆ 8T Mini Spider Crane Specifications
| Item | 3-Ton Model (Standard) | 5-Ton Model (Main) | 8-Ton Model (Heavy-Duty) |
| Max. Rated Lifting Capacity(tons） | 3t | 5t | 8t |
| Driving Type | Rubber track travel | Rubber track travel | Rubber track travel |
| Outrigger Type | Foldable outriggers | Flat-folding outriggers | |
| Power System | Dual fuel/electric (three-phase power) | ||
| Gradeability | 20° | ||
| Control Mode | Wireless remote / panel switches | ||
Expert recommendation: Models under 3 tons typically use folding outriggers for greater maneuverability; models over 5 tons use flat-out outriggers for better stability, making them suitable for more challenging outdoor lifting operations.
Top 5 benefits of Mini Tracked cranes
Compact Size, Powerful Performance
With its compact design, the small spider crane can operate freely in confined spaces such as indoor areas, rooftops, shopping malls, and tunnels, yet its lifting capacity far exceeds that of equipment of similar size.
Simple Operation, Safe and Reliable
Featuring wireless remote control, a single operator can complete lifting tasks, eliminating the high risks associated with manual handling. Optional torque indicators and anti-tipping alarm systems further enhance operational safety.
Dual-Power (Diesel/Electric) with Strong Adaptability
YG mini tracked cranes support both diesel and electric power. Export orders can be customized to match local voltage and frequency standards, making it suitable for global markets.
Extensive Configuration Options and Customization
Optional accessories include work platforms, auxiliary booms, jibs, remote controls, and torque indicators to accommodate various construction scenarios. The tracked mini crane’s color can also be customized at no extra cost.
Easy to Transport and Low Operating Costs
Small spider crane compact design facilitates transportation and site relocation, reducing logistics costs. The track-based travel system exerts minimal ground pressure, making it suitable for a wide range of indoor and outdoor surfaces.
Mini Spider Crane vs. Traditional Crane
| Aspect | Small Spider Crane | Traditional Heavy Crane (Truck Crane / Large Crawler Crane) |
| Working Space | Extremely flexible: can operate indoors, on rooftops, in basements, and narrow alleys. | Severely restricted: requires spacious sites and cannot enter indoor areas. |
| Transport & Site Access | Low cost: can be transported by standard trucks, and can even fit into elevators. | High cost: requires special permits for oversized loads, with expensive mobilization fees. |
| Power Mode | Dual fuel/electric: uses electricity indoors (zero emissions, low noise) and diesel outdoors. | Single power source: typically diesel only, with high exhaust emissions, unsuitable for indoor use. |
| Ground Impact | Ground-friendly: rubber tracks plus outriggers distribute weight evenly, reducing pressure and avoiding damage to flooring. | High impact: extremely heavy, can easily damage road surfaces and underground pipelines. |
| Operating Cost | Single-person operation: wireless remote control provides unobstructed views and a short learning curve. | Multi-person operation: requires a dedicated operator and signal person, with limited visibility. |
| Construction Safety | High precision: equipped with a moment limiter, offering strong spatial stability. | Increased risk: prone to collisions in confined spaces. |
Applications of Small Spider Crane
• Curtain Wall Glass Installation: When used with vacuum suction cups, it allows for the easy installation of large floor-to-ceiling glass panels indoors or on terraces.
• Factory Equipment Maintenance: Navigate narrow aisles in workshops filled with precision instruments to transport and install machine tools.
• Substations and Electrical Construction: Excellent insulation properties and a compact design make it the top choice for substation maintenance.
• Cemetery and Landscaping Construction: Lifts and transports stone materials in rugged terrain and confined spaces within gardens or cemetery areas.
• High-Altitude and Roof Work: Its lightweight design allows it to be transported to rooftops by large small spider crane for the installation of signal towers or air conditioning units.
Mini Spider Crane Operating and Purchasing Guidelines
As a manufacturer, we are not only committed to the performance of our machines but also to your safety on the job site.
Export Confirmation (Voltage and Language)
Since the mini tracked crane is a hybrid (gas/electric) model, international customers must specify the following when placing an order: the local phase configuration, voltage (V), and frequency (Hz). Additionally, our remote controls and torque indicators come standard with both Chinese and English interfaces. If you require an English-only interface or other languages (such as Russian or Spanish), please specify this in advance for customization.
Outriggers and Ground Conditions
Before operation, ensure that small spider crane all four outriggers are firmly supported on solid ground. When working on soft soil, be sure to use dedicated outrigger pads.
Lifting Limits
Overloading is strictly prohibited. Before operation, use the torque display to verify that the load weight and working radius fall within the safe operating limits.
Maintenance and Inspection
Regularly inspect the wear on the rubber tracks and check the hydraulic oil pressure. Ensure the wireless remote control system has sufficient battery power.
