In Slovakia, an underground sewage pipe network upgrading project in the old town area faced the following challenges: the construction site was located between densely arranged residential buildings, making it impossible for traditional large-scale equipment to enter. Additionally, the construction had to protect the historical district to the greatest extent and minimize interference to residents. In response to this demand, the technical team of YG Company conducted an in-depth analysis and accurately recommended a 3-ton spider crawler crane, providing a perfect solution for the project.【WhatsApp/WeChat/Phone】+86 13837122632

Customer Requirements
When the customer searched extensively for “spyder crane for sale” information in the early stage of the project, their core demands were very clear:
- Extreme Space Challenge: The width of some lanes was less than 3 meters, requiring the equipment to have extremely small retracted and deployed dimensions.
- Ground Protection Requirement: The ancient road surfaces could not withstand the rolling of heavy equipment, so the crawler’s ground pressure needed to be low.
- Quiet Construction Restriction: The residential area was sensitive to noise, so the equipment needed to have a low-noise or silent operation mode.
- Based on these requirements, the YG team recommended the YG-3 model, precisely because it, as a top-tier Mini Spider Crane, achieves a perfect balance between extreme compactness and strong performance.
Customer’s On-Site Inspection of the Spider Crawler Crane
To ensure everything went smoothly, the Slovak customer made a special trip to YG’s factory in China for on-site verification. The key focuses of this visit included:
- Production Line Tracing: Touring the modern assembly line to understand the rigorous process control.
- Core Component Inspection: Focusing on the manufacturing quality of the hydraulic system, outrigger structure, and crawler chassis.
- Customization Plan Communication: In-depth discussions with engineers on potential special working conditions at the project site and corresponding countermeasures. This inspection laid a solid foundation of confidence for the final purchase of this high-performance Spider Crawler Crane.
Why Choose YG’s Spider Crawler Crane
The advantages of YG’s equipment are specific and remarkable:
- Flexible and Stable Outriggers – The four hydraulic outriggers can independently extend/retract and swing at any angle. Even on the edge of uneven excavation trenches, it can quickly form a stable support platform with a minimal footprint.
- Stable Hoisting, Precise and Efficient – Equipped with a high-strength wear-resistant hook and a precision winch system, it operates stably when lifting 5-meter-long concrete sewage pipes, achieving millimeter-level precise positioning in narrow spaces.
- Crawler Travel, Smooth as on Flat Ground – The chassis adopts engineering rubber crawlers, which not only perfectly protect the ancient street slate pavement but also provide excellent climbing and obstacle-crossing capabilities, enabling stable movement and operation on a 25° slope.
- Compact Size, Flexible Movement – After retraction, the equipment has a small height and width, allowing it to easily pass through low arches and narrow alleyways to reach construction points that traditional cranes cannot access.
- Dual Oil-Electric Mode, Suitable for Both Quiet and Heavy Work – Standard with hybrid oil-electric power. In electric mode, the noise is extremely low, allowing non-disturbing construction during residents’ rest hours; the fuel mode ensures continuous heavy-load operation capabilities.
Customer’s High Praise for This Spider Crawler Crane
After the project was completed, the customer highly praised: “This Crawler Spider Crane exceeded our expectations. It not only solved the problem of on-site access but also its remote control function allowed one operator to complete all hoisting and movement tasks, saving a lot of manpower and time. It is our ‘ultimate tool’ for working in the old town.” This feedback strongly confirms the excellent applicability of YG’s equipment.
