Working Principle of Mobile Cranes
Mobile cranes operate on the core principle of hydraulic transmission and pulley systems. A hydraulic pump converts mechanical energy into hydraulic energy, driving hydraulic cylinders and motors to perform boom extension, luffing, slewing, and lifting operations. Simultaneously, a combination of fixed and movable pulleys amplifies the lifting force, achieving the effect of lifting heavy objects with minimal effort. The entire machine consists of four main parts: a metal structure (boom, chassis, turntable, counterweight), working mechanisms (lifting, extension, luffing, slewing, and traveling), a power system, and a control system. Outriggers, tracks, or tires maintain operational stability, and the 360° rotation design covers all angle lifting needs.
Main Types of Mobile Cranes for Sale
- Small Crawler Cranes: Utilize a crawler chassis, offering a large ground contact area and high stability. They can operate on soft, muddy ground and can travel while lifting loads without outriggers, making them suitable for small to medium-sized projects and complex terrain.
- Mini Spider Cranes (Mini Cranes): Belonging to the category of compact cranes, these are small in size with retractable outriggers, resembling a spider. They can access areas inaccessible by traditional equipment, such as elevators, indoor spaces, and narrow alleyways. They are remotely operated, safe, and efficient.
- Compact Cranes: Includes small truck cranes and light-duty tire cranes. They are compact, easy to move, and suitable for both road travel and on-site operations, ideal for small-scale urban construction and equipment handling.
- Large Mobile Cranes: Includes truck cranes and all-terrain cranes. They have large lifting capacities and high travel speeds, suitable for large-scale infrastructure projects, bridge hoisting, and heavy equipment handling.

Core Advantages of Mobile Cranes
1. High Mobility and Adaptability to Various Scenarios
Unlike stationary cranes, mobile cranes can move autonomously or be quickly relocated. Small crawler cranes adapt to soft terrain, mini spider cranes overcome space limitations, and compact cranes are suitable for both urban roads and construction sites. No pre-laying of tracks or foundation pouring is required; they can quickly commence operations upon arrival, significantly improving construction efficiency.
2. Convenient Operation and High Safety
Mainstream models are equipped with both wireless remote control and manual operation modes. Operators can stay away from the lifting area, maintaining a clear view and avoiding risks. Equipped with safety systems such as torque limiters, overload protection, and emergency stop, they monitor the operating status in real time, eliminating safety hazards such as tipping over and overloading. Mini cranes and other smaller models are more suitable for scenarios with precise and high safety requirements.
3. High Efficiency and Controllable Costs
Operation can be completed by 1-2 people, saving significant labor costs; mobile cranes cover a wide area with a single lifting operation, and can be moved without disassembly, shortening the construction cycle; the equipment is multifunctional and reusable, capable of lifting, handling, and high-altitude operations (with optional work baskets), making mobile cranes far more cost-effective than single-function equipment.
4. Compact Structure and Simple Maintenance
YG’s compact cranes and mini spider cranes adopt a modular design, are small in size and lightweight, and easy to transport; core components are standardized, and vulnerable parts are easy to replace; daily maintenance only requires periodic lubrication and inspection of the hydraulic system, reducing long-term operating costs.

Mobile Crane for Sale FAQs
Q1: How to choose between a mini spider crane and a small crawler crane?
A: The key factor is the working space and terrain: Mini spider cranes are suitable for small spaces such as indoors, elevators, and narrow alleys, without damaging the ground; small crawler cranes are suitable for complex terrains such as muddy, soft, and sloping ground, and can move while lifting. You can directly consult the YG mobile crane manufacturer for scenario-specific selection advice.
Q2: What parameters should I focus on when purchasing a mobile crane?
A: Focus on four key indicators: ① Rated lifting capacity (matching the weight of the material being lifted); ② Maximum lifting height and working radius (suitable for working height and range); ③ Chassis type (crawler/tire/mini spider, matching the terrain); ④ Power system (diesel/electric, suitable for indoor and outdoor use). Also, choose reputable mobile crane sales channels to ensure quality and after-sales service.
Q3: What are the after-sales guarantees for mobile cranes?
A: As a professional mobile crane manufacturer, YG provides comprehensive after-sales service: 1-year free warranty on all models, lifetime supply of spare parts at cost price; 30+ service outlets nationwide, 24-hour response to fault reports; free operation training and remote technical guidance to ensure worry-free use of mobile cranes after purchase.
Q4: What are the key points for daily maintenance of mobile cranes?
A: Daily maintenance requires attention to three points: ① Check the hydraulic oil and filter after each operation and replace them promptly; ② Regularly lubricate the rotating and telescopic parts to prevent wear; ③ Store in a dry and ventilated place to avoid rainwater corrosion of the electrical system; regularly inspect and replace vulnerable parts (hooks, wire ropes).
