Project Background

• Customer type: A local professional building maintenance company in Portugal, undertaking the facade renovation of historic buildings in the old town of Porto.
• Site challenges: The narrowest alley is only 1.6 meters wide; traditional truck cranes cannot enter at all. The old buildings have stone-paved roads, requiring equipment with low ground pressure to avoid damaging the surface.
• Operation requirements: Lift stone and steel structures weighing up to 3 tons to a height of three floors (about 12 meters), and turn at multiple narrow corners.
• Solution search: The customer once looked for a spider lift crane in the European market, but faced high prices and long delivery times, so they finally turned to Chinese manufacturers.

Why Choose YG Crawler Spider Crane?

• Compact size for narrow alleys: The YG5 spider lift crane is only 1.5 meters wide, easily passing through 1.6meter alleys. The crawler travel system allows pivot turning for flexible maneuvering in tight spaces.
• Rubber tracks protect the ground: Engineering rubber tracks create low ground pressure, leaving no marks on the stone roads of Portugal’s old town, meeting heritage protection requirements.
• Hybrid power for strong adaptability: The old town has many tourists in the daytime, requiring lownoise operation — the electric mode meets this perfectly. At night or in outdoor areas, it can switch to diesel mode with no range worries.
• Wireless remote control improves safety: The operator can stand at the best viewing position to control the machine, accurately adjusting the boom and outriggers even in blind narrow alleys to avoid hitting buildings.
• Customized to meet European standards: According to the customer’s request, YG changed the control panel labels to Portuguese, added Europeanstandard safety locks, and the whole machine is CE certified.

Practical Application of Crawler Spider Crane

• On-site arrival and unloading: The machine was delivered by small truck to the alley entrance, then drove into the construction site under its own crawler travel system, with no extra handling equipment needed.
• Adaptive outrigger adjustment: The alley ground is uneven, even with steps. The hydraulic outriggers of the YG small spider crane adjust angle and height independently, leveling the machine on slopes for stable lifting.
• Passing through narrow passages: When moving to another work point, the machine retracted its boom, crossed a 1.6meter arch in folded state, and redeployed for work — all in just 10 minutes.
• Accurate highaltitude lifting: When installing stone at 12 meters, the wireless remote control enables micromovement, with smooth hook positioning and centimeterlevel accuracy. The customer praised that the controllability of this track crane for sale is better than European brands they rented before.

Customer Feedback

“We initially had concerns about Chinese-made small spider crane, worrying about quality and after-sales service. But the YG team supported us professionally from selection, customization to shipping. After arrival, they also guided us remotely for commissioning.In actual use, the flexibility and stability of this crawler spider crane exceeded expectations, especially its passability in narrow alleys.”— Sr. António, Project Manager, Portuguese Customer

Daily Maintenance Guide for Crawler Spider Crane

• Track cleaning: After daily use, check for stones stuck in the rubber tracks and clean them promptly to avoid abnormal wear.
• Hydraulic oil check: Check the hydraulic oil level weekly and top up if low. It is recommended to replace the hydraulic oil every 1000 hours.
• Outrigger lubrication: Regularly apply grease to the telescopic parts of the outriggers to prevent jamming after long outdoor use.
• Wire rope maintenance: Inspect the wire rope monthly for broken strands or flattening. Apply special grease if needed to extend service life.
• Battery maintenance: Charge the battery in time after electric operation. If not used for a long time, start the engine or charge every two weeks to keep battery activity.
• Remote control storage: Put the remote control in a waterproof box after use, avoid direct sunlight or rain to prevent key aging.
