As urban areas grow denser and existing infrastructure ages, contractors worldwide face increasingly complex lifting challenges. Traditional truck cranes require large open spaces for setup and operation, making them unusable for projects in narrow streets, interior courtyards, or finished buildings. Manual lifting methods are slow, labor-intensive, and carry significant safety risks, especially when working at height. A mobile spider crane fills this critical gap in the market, offering a unique combination of compact size, impressive lifting capacity, and unmatched maneuverability. These machines have revolutionized how small to medium-sized lifting jobs are completed, allowing contractors to take on projects that were previously impossible or uneconomical.

Case Study: Mobile Spider Crane for Urban Construction Projects in France
Customer Background:
Our customer is a family-owned small construction and maintenance company based in France. They have operated for 12 years, focusing on old building renovation, rooftop repair and small-scale urban construction projects, serving private residential owners, small retail shops and local apartment management companies. They run a tight-knit team of 8-10 full-time workers, handling most projects in-house to maintain consistent work quality and control project timelines.
Customer Requirements:
Before contacting us, the customer relied on manual hoists and small wheeled forklifts for all lifting work, which had become a major bottleneck in their daily operations. They needed a compact lifting solution that could fit through standard doorways and navigate narrow cobblestone streets less than 3 meters wide, had sufficient lifting height to reach rooftops up to 17 meters high, and exerted low ground pressure to avoid damaging old stone pavements and finished indoor floors. They also preferred a machine with simple operation and maintenance procedures, as they did not have dedicated heavy equipment operators on their team.
YG’s Solution and Customer Feedback:
After carefully reviewing their project portfolio and typical lifting requirements, we recommended our YG-5 mobile spider crane. This model offered the perfect balance of compact size and performance, with a 1.5-meter transport width that fits through any standard doorway, a 16.8-meter maximum lifting height, and a 5-ton rated lifting capacity. The customer completed unpacking and commissioning in just 1 day using our detailed step-by-step video guides and a single 15-minute remote video call to clarify the outrigger leveling process.
After two months of daily operation, they reported that their lifting efficiency had increased by approximately 60%, they could now accept all the projects they previously had to turn down, and they had completely eliminated the need to rent external cranes for small jobs. They particularly praised the remote control feature, which allows a single operator to perform lifts safely from the best vantage point, and the low ground pressure design that has not caused any damage to the stone pavements they work on.
Core Design Features That Solved the Client’s Pain Points
Every feature of our mobile spider crane was engineered to address the specific challenges of urban and confined space lifting. The French customer found that four design features in particular were instrumental to their success:
- Five-section pentagonal telescopic boom: The boom’s unique pentagonal cross-section provides superior rigidity and stability compared to traditional square or rectangular booms. This allows for more precise lifting and reduces sway, even at maximum height. The boom extends from 3.1 meters to 12.3 meters in just 54 seconds, allowing operators to quickly adjust to different lifting requirements.
- Independent adjustable outriggers: You can adjust the four outriggers independently to any length, allowing you to set up the crane safely on uneven surfaces such as cobblestone streets and sloped ground. This was a critical feature for the French customer, who frequently works on uneven historic sites where level ground is rare.
- Dual operation modes: The tracked mini crane can be operated both manually from the control panel and remotely via a wireless remote control. The remote control allows the operator to stand at the best vantage point for the lift, improving visibility and safety. This is particularly useful in confined spaces where the operator cannot stand near the crane.
- Lightweight tracked chassis: The rubber tracks distribute the machine’s weight evenly across the ground, resulting in a ground pressure of just 0.5 kg/cm². This is less than the pressure exerted by an average adult standing on one foot, meaning the crane can drive directly on delicate stone pavements, finished concrete floors, and even grass without causing damage.
