The small spider crane is a specialised, compact lifting device designed for material handling and precision installation in confined spaces where traditional large cranes cannot safely access or operate. Due to its flexible site relocation capabilities, it is also widely known as a mobile spider crane, and because of its crawler-mounted structure, it is also called a spider crawler crane. It has become an indispensable solution for modern engineering projects requiring high-precision, confined-space lifting operations. The device gets its name from its spider-like, retractable outriggers, which provide excellent load-bearing stability even in spaces with limited space, when fully extended. When folded, its ultra-compact body easily passes through narrow doorways, corridors, and standard elevators, breaking through the spatial limitations of traditional lifting machinery.

6 Advantages of the YG Small Spider Crane:
1. Ultra-Compact Body for Confined Space Access
The series features an ultra-miniaturised design. The smallest YG 3 ton spider crane has a transport size of only 2950*980*1560mm and 2700kg total weight, easily fitting standard elevators, narrow corridors and streets, perfectly adapting to hoisting in confined spaces inaccessible to traditional large cranes.
2. Stable Lifting Performance with Robust Structure
All models adopt a 5-section pentagonal boom for superior load-bearing and anti-deformation performance, with a boom angle adjustable from 0° to 78°. Retractable spider outriggers form a stable support base, paired with 360° continuous slewing for all-round dead-angle-free lifting, ensuring safe, stable operation under rated load.
3. All-Terrain Adaptability for Complex Job Sites
As a heavy-duty spider crawler crane, it uses a hydraulic motor-driven crawler walking structure with a 0~2.5km/h walking speed. It moves smoothly on flat indoor floors and uneven outdoor sites, with a 36% (25°) grade ability to handle sloped terrain, and its low ground pressure design avoids damage to finished floors and lawns.
4. Dual Control Modes for Simple & Safe Operation
All models support manual operation and optional remote control, with a user-friendly operating system. Workers can master standard operation after just 1-2 hours of training, no professional crane operator required. The remote control function lets operators stay away from the lifting area, greatly improving on-site construction safety.
5. High-Efficiency Operation to Shorten Project Cycles
The small spider crane completes on-site installation and debugging quickly, ready for operation immediately after arriving at the site. It boasts efficient boom adjustment: the YG-3 finishes full boom telescoping in 20 seconds, and all models complete boom angle adjustment in 13 seconds, cutting auxiliary construction time and boosting overall work efficiency.
6. Diversified Model Options for Full Scenario Coverage
This small spider crane series offers three targeted models to match varied project needs: the YG-3 (3t) for small indoor precision installation and light hoisting; the YG-5 (5t) and YG-8 (8t) for municipal maintenance, industrial equipment installation and medium-scale outdoor projects. No matter your project type, we have a suitable mini spider crane for sale to meet your needs.
3 Steps To Choose The Right Model for You Quickly
- Prioritise your construction space limits: If your projects are mainly indoor installation, high-rise fit-outs requiring elevator transport, or operations in extremely narrow streets and corridors, the YG-3 model is the optimal choice, as its ultra-compact body can easily pass through confined spaces. For outdoor municipal maintenance and industrial plant projects with sufficient operating space, you can consider the YG-5 or YG-8 model.
- Confirm your core lifting parameters: Focus on your actual required lifting weight, maximum working height and working radius, rather than only the rated maximum lifting capacity. For light hoisting within 3t and working height below 10m, the YG-3 fully meets your needs. For projects with 5-8t lifting demand and working height up to 16-18m, choose the YG-5 or YG-8 model accordingly.
- Match your project type and operation frequency: If you frequently transfer between scattered small projects such as shop fit-outs and street lamp maintenance, the lightweight YG-3 is more convenient for transportation and site transfer. If you undertake long-term continuous large-scale projects such as industrial equipment installation and municipal engineering, the YG-5 and YG-8, with higher operating efficiency, are more suitable.
If you are still unsure about model selection, you can contact YG directly, and we will provide professional, targeted selection suggestions based on your specific project details.
Should You Buy or Rent a Spider Crane?
The choice between buying or renting a small spider crane comes down to your usage frequency, project needs and long-term cost plans.
Renting only makes sense for short-term, one-off projects (usage under 1 month) or teams with extremely low annual lifting demands, as it avoids a large one-time capital outlay for temporary needs. For most teams with regular ongoing projects, buying is the more cost-effective long-term choice. If you have over 3 months of cumulative lifting work annually or need flexible scheduling for multi-site jobs, owning your own machine eliminates repeated rental costs and gives you full control over equipment condition. Our YG series, a durable mobile spider crane, has ultra-low daily maintenance costs, and this reliable spider crawler crane can help you build stable business competitiveness with consistent performance.
If you decide to buy, we have a full range of mini spider crane for sale, with YG-3, YG-5 and YG-8 models to match your project requirements and budget.
