A 5-ton spider crane is a compact, versatile lifting machine engineered to deliver reliable heavy lifting performance in tight, confined spaces where traditional cranes cannot access. It is designed for precision lifting tasks, combining flexible mobility with stable load capacity, making it suitable for indoor equipment installation, narrow-site construction, high-altitude maintenance, and specialized lifting projects. At YG, we manufacture high-quality lifting solutions, including our YG-5 model, built with robust engineering and precise control systems to meet diverse medium-duty lifting demands across industries.

Working Principle of a 5 Ton Spider Crane:
This machine adopts a full hydraulic transmission system as its core drive architecture. The power unit drives the hydraulic pump to deliver stable pressure oil to the whole system, converting hydraulic energy into mechanical energy to achieve precise control of all working actions. The hydraulic cylinder drives the 5-section pentagonal telescopic boom to extend and retract within 3.1m-12.3m, and controls the boom to adjust the angle between 0°~78°, to flexibly match the required working radius and lifting height. The hydraulic motor drives the winch system to realize 0-12m/min hook lifting, and controls the main body to complete 0-360° continuous slewing, adapting to all-around lifting demands. During operation, the hydraulic outriggers are deployed to form a multi-point stable support system, which offsets the overturning moment generated by lifting loads, ensuring safe and stable operation in narrow spaces. The hydraulic crawler walking system, driven by a hydraulic motor, realizes flexible site movement and adapts to complex, uneven ground.
Case Study: YG 5 Ton Spider Crane Project in Kazakhstan
Customer Background：
The customer is a local engineering company in Kazakhstan, focusing on urban commercial complex renovation and indoor electromechanical installation, with long-term undertakings of old building upgrading and shopping mall equipment renewal projects in the downtown area.
Customer Need：
The customer needed equipment to complete 3-5t lifting of electromechanical equipment and curtain wall components, with a maximum working height of about 16m. Most of the working sites are narrow downtown lanes and indoor confined spaces, requiring a compact body that can pass through standard doorways and narrow passages, and also needs good terrain adaptability for uneven ground of suburban projects.
YG’s Matching Solution：
Combined with the customer’s full-scene demands, YG recommended the YG-5 5-ton spider crane. Its 5t rated lifting capacity, 16.8m maximum lifting height and 14m working radius fully match the core lifting demand; the 500015001900mm compact transport size adapts to narrow space traffic; the 36% grade ability of hydraulic crawler drive meets the complex terrain demand, and the optional remote control function also fits the safety and visibility requirements of indoor operation.
Customer Feedback：
The customer said that this crawler spider crane perfectly adapts to various narrow-space lifting scenarios of their downtown renovation projects. The equipment runs stably with high lifting accuracy, which greatly shortens their project construction cycle and has become the core equipment for their confined space operations.
How to maintain your Crawler Spider Crane?
- Daily Pre-Use Checks: Inspect hydraulic lines for leaks, wire rope for wear, and all safety components before every operation to avoid costly disruptions to your mobile spider crane’s work.
- Hydraulic System Care: Change hydraulic oil and filters at recommended intervals, and monitor oil quality regularly to ensure smooth, precise control of your crawler spider crane’s core functions.
- Regular Lubrication: Lubricate telescopic boom joints, slew bearings, and winch components on schedule to reduce friction and extend the service life of your 5-ton spider crane.
- Structural Inspections: Periodically check the boom, welds, and outriggers for stress or damage to maintain stable, safe lifting performance for every project.
