12 Ton Crawler Spider Crane

RLD12T 12-Ton Crawler Spider Crane Specifications

Explore the full technical configuration of our flagship heavy-duty RLD12T 12-ton mini crawler crane. Engineered to deliver maximum lifting capacity, robust outreach, and superior stability in highly restricted job sites.

Engineered for Global Standards: Unmatched Heavy-Duty Power in Restrained Spaces

At Qingdao Rolande, we engineer our high-capacity equipment to meet the strict structural, environmental, and safety regulations of international markets, including North America, Europe, and Australia. The RLD12T 12-ton crawler spider crane is specifically designed to handle high-tonnage lifting challenges while operating seamlessly under tough localized requirements:

Strict Emission Compliance & Dual Power Flexibility: To fit seamlessly into high-standard urban eco-zones, we offer premium EPA-certified Yanmar engines and highly efficient Euro 5 engines. Paired with our on-board dual-power electric system (50Hz/60Hz, 220V-380V triple-phase), operators can instantly switch to clean electric power for indoor industrial maintenance, basement overhauls, or emission-restricted indoor project areas.

With an ultra-slender transport width of only 1800mm, this heavy-duty 12-ton powerhouse moves easily through tight access points where traditional truck cranes simply cannot deploy. Its robust commercial rubber tracks spread weight effectively to minimize ground pressure on sensitive tile or concrete pavements, while delivering a commanding 32° gradeability to easily climb steep site inclines.

Why Choose the RLD12T Crawler Spider Crane?

• Exceptional 12-Ton Capacity Class: Delivers an incredible 22-meter lifting height and a 21-meter working radius, making it the absolute gold standard for heavy multi-story curtain wall glass glazing and structural steel framework assembly.

• Intelligent Safety Systems: Fully upgradeable with high-precision Duman graphical Load Moment Indicators (LMI), 3-wrap winch alarms with anti-two-block hook systems, and a triple-terminal interlocking system (Travel/Outrigger/Boom) to securely monitor load variations and eliminate tipping hazards.

• Hexagonal High-Rigidity Boom: The robust 5-section hexagonal full-automatic boom drastically minimizes structural bending and lateral swaying under heavy loads, giving operators elite millimeter-level precision at peak reach.

• Versatile Site Adaptation: The heavy-duty frog-style stability outriggers feature single side horizontal extension up to 3.2m to safely brace around structural obstacles. It seamlessly integrates specialized attachments including manual/hydraulic fly jibs, high-altitude rotatable man baskets, and heavy glass vacuum suction lifters.

Frequently Asked Questions (FAQ)

1. Can I legally operate the RLD12T crane under US EPA or European eco-regulations?

Yes, absolutely. For global construction projects requiring strict compliance, we offer optional premium configurations featuring genuine Yanmar EPA-certified engines and Euro 5 compliant systems. This ensures your machine successfully satisfies local emission codes and passes job site environmental inspections seamlessly.

2. How does the hybrid diesel-electric power configuration work for indoor jobs?

The RLD12T features a flexible built-in hybrid drive supporting dual frequencies (50Hz/60Hz) across 220V-380V power grids. Operators can travel to and maneuver around the job site using diesel power and then plug directly into the local industrial facility grid for 100% quiet, exhaust-free indoor operation.

3. What safety features are in place to ensure heavy lifting precision at 22 meters?

Operational safety is our primary focus. The crane can be configured with the high-end Duman intelligent remote control system and graphical load moment sensors. These systems actively calculate real-time load distribution and structural stress, automatically restricting hazardous crane movements if operational thresholds are approached.
