In Portugal, a company specializing in curtain wall and glass installation was facing a recurring headache. Their projects involved high‑rise buildings with narrow loading bays, low‑clearance underground parking, and rooftop access only via service elevators. A conventional truck crane was too large to enter these spaces. Manual lifting was unsafe and slow. They needed a machine that could fit through a standard doorway, lift 5 tons, and operate on sensitive roof surfaces.
After evaluating several options, they purchased a 5 ton crawler crane from YG Machinery. This 5 ton spider crane for sale features a 5‑segment telescopic boom reaching 16.5m, a 360° continuous rotation, and a compact body just 1.5m wide and 1.9m tall. The rubber tracks distribute weight evenly, protecting finished floors. The remote control allows the operator to stand clear while placing glass panels with millimeter precision.
The result transformed their workflow. The Portugal crew now completes glass installations in half the time, with zero floor damage and no worker injuries. The 5 ton crawler crane paid for itself within nine months through labor savings and faster project turnover.

Three Challenges That Made Traditional Lifting Impossible In Portugal
The Portuguese contractor faced three problems common to urban construction across Southern Europe.
Problem 1: No Access for Large Cranes
Portugal‘s historic districts and modern high‑rises alike have narrow streets, low parking garage ceilings, and loading bays designed for vans, not truck cranes. A 30‑ton truck crane simply cannot get close to the building. The crew had to carry glass panels up stairwells – slow and dangerous.
Problem 2: Floor Loading Limits
Rooftop equipment rooms, terraces, and even indoor floors often have weight restrictions. A 5‑ton wheeled crane concentrates load on small tire contact patches, cracking tiles or punching through lightweight decks. The spider crane‘s long tracks distribute weight over a large area, staying within safe limits.
Problem 3: High Precision Required for Glass Installation
Curtain wall panels weigh hundreds of kilos and cost thousands of euros each. A single mistake during hoisting can shatter the glass or damage the building envelope. The crew needed fine control – slow, steady lifts with immediate response to joystick commands.
The 5 ton crawler crane solved all three by combining compact dimensions, low ground pressure, and smooth hydraulic controls.
How The 5 Ton Crawler Crane Transformed Glass Installation?
The YG 5‑ton spider crane is designed for exactly this kind of work: lifting heavy loads where no other crane can go.
Fits Through Standard Doors
At 1.5m wide and 1.9m tall, the machine rolls through double doors and into freight elevators. For tighter spaces, the outriggers can be manually folded, and the boom retracted. The Portuguese crew routinely moves the crane between floors using the building‘s service lift (after checking weight capacity).
Stable on Any Surface
Four hydraulic outriggers extend wide, up to 7.8m side to side. Each outrigger foot has a large pad. The 6.2‑ton crane becomes a rigid platform. Even when lifting 0.5 tons at a 14m radius, the machine remains level. The 25° climbing ability lets it drive up loading ramps.
Precision Control
The wireless remote gives the operator a clear view of the load. The variable‑speed winch allows micro‑movements. The Portugal crew lifts glass panels, rotates 360°, and lowers them into frames with no swinging or bouncing. The optional torque limiter prevents overload accidents.
Indoor‑Friendly Power
The standard diesel engine works outdoors. For indoor use, the customer can order an electric motor version – zero emissions, quiet operation. The Portuguese contractor uses diesel for rooftop work and plans to add an electric unit for shopping mall interiors.
Real Feedback From The Portugal Glass Installation Team
After eight months of using the 5 ton spider crane for sale, the project manager shared his results.
- Access time: Previously, moving glass panels to a rooftop took 4 hours using a combination of manual carrying and a small hoist. Now the crane drives into the service elevator, reaches the roof in 15 minutes, and is ready to lift.
- Installation speed: One glass panel now takes 20 minutes from pickup to final placement. The old method took 50 minutes.
- Damage incidents: Zero cracked panels, zero cracked floor tiles. The old method caused one broken glass every three months.
- Labor: Reduced the lifting crew from 4 people to 2 (one operates the crane, one guides the panel).
- Customer satisfaction: Building owners appreciate that the crane does not tear up landscaping or roof membranes.
The project manager said, “We looked at mini cranes from several brands. The YG 5 ton crawler crane offered the best combination of lifting height, compact size, and price. The remote control is intuitive – a new operator learns it in one hour. The outriggers set up in two minutes. It is the most useful tool we have bought in ten years.”
An operator added: “I have used spider cranes before, but this one‘s 360° continuous rotation is a game‑changer. I never have to reposition the tracks. And the rubber tracks do not mar the marble floors in the lobby.”
Which Spider Crane Model Fits Your Needs?
The 5‑ton model is the most popular for glass installation, HVAC replacement, and steel erection in confined spaces. However, YG offers other capacities.
- 3‑ton spider crane (3t, smaller footprint): For indoor work in very tight spaces – office renovations, museum installations, residential elevator shafts.
- 5‑ton spider crane (our Portuguese case): The sweet spot for commercial curtain wall, rooftop HVAC units, and factory maintenance.
- 8‑ton spider crane (8t, longer boom): Heavy industrial, bridge repair, large‑scale glass where the 5t reach is insufficient.
All models can be ordered with:
- Electric or diesel power
- Wireless remote control (standard on some, optional on others)
- Torque limiter/overload protection
- Manual or hydraulic outriggers
- Custom paint and decals
