Ruhr, Almanya'da Yeraltı Madenciliği için Hidrolik Koruyucu Kanopili Özel 6 Tonluk Araç Üstü Makaslı Lift

Müşteriye Genel Bakış

This technical deployment focused on the engineering and integration of a specialized 6-ton scissor lift platform designed for underground utility vehicles in the Ruhr region, Germany. The project was commissioned by a leading German mining services provider specializing in the maintenance of underground infrastructure and salt mining operations.

The core requirement was a mobile lifting solution that could be permanently integrated into the chassis of a heavy-duty mining truck. Unlike stationary industrial lifts, this [Internal Link: vehicle-mounted scissor lift] had to maintain structural integrity under the dynamic vibrations of a moving vehicle while operating within the tight spatial constraints of underground tunnels. The platform’s primary function is to facilitate the installation and maintenance of overhead ventilation ducts and electrical conduits, necessitating a bespoke “canopy” system to protect personnel from falling rock and debris.

Adherence to German industrial safety standards, specifically DIN EN 1570-1 and DIN EN 280, was a mandatory prerequisite for the equipment’s certification and operational deployment within the European Union.

Zorluk ve Çözüm

Müşteri Zorlukları

The engineering constraints for this project were significantly higher than those for standard warehouse applications. The client faced several critical bottlenecks in their existing maintenance fleet:

  • Chassis Integration and Stability: Standard lifts lack the mounting points for vehicle chassis integration. The project required a base frame capable of being welded/bolted directly to a 24V mobile chassis without compromising the vehicle’s center of gravity.

  • Overhead Safety in Mining Zones: In underground mining, falling debris is a constant hazard. The client required a solution that provided a “safe zone” for operators even when the platform was at maximum extension.

  • Power Supply Limitations: The lift needed to operate entirely on the vehicle’s 24V DC electrical system rather than standard 380V industrial power, requiring high-efficiency hydraulic pumps and specialized control valves.

  • Personnel Access in Tight Spaces: Standard platform railings often obstruct entry in narrow tunnels. The design required a folding access mechanism that did not increase the stowed height of the vehicle.

  • Extreme Thermal and Environmental Stress: Operation in temperatures ranging from -20°C to +60°C demanded high-grade hydraulic seals and specific viscosity-stable fluids to prevent system failure during shift transitions between surface and deep-mine environments.

GRADIN Özel Çözüm

To address these technical requirements, our engineering team developed a customized scissor platform utilizing high-strength 16# channel steel and a redundant hydraulic architecture.

1. Structural Design and Material Science
The scissor linkage is constructed from 220mm x 40mm solid steel plates, chosen for their exceptional resistance to lateral shear forces. This is particularly important for vehicle-mounted units where the ground may not be perfectly level. The platform itself features an 8mm chequered plate surface to ensure anti-slip performance in humid underground conditions. The structural frame was treated with a high-visibility RAL yellow polyurethane coating, meeting the [External Link: German DIN standards for industrial visibility].

2. Specialized Hydraulic Canopy System
A standout feature of this solution is the independent hydraulic canopy. Measuring 855mm x 835mm, this overhead shield is powered by dedicated cylinders with a 530mm stroke. This allow the canopy to be raised once the personnel are in position, providing 100kg of overhead protection and integrated 24V LED work lighting. This ensures that even in low-visibility environments, the work zone is illuminated and shielded.

3. Mobile Control Architecture
The control system was designed for 24V DC operation, utilizing a dual-operator interface: one manual control station at the vehicle base and a secondary electronic control unit on the platform. To ensure safety, we integrated a quad-valve manifold  with two redundant lines. This ensures that in the event of a primary valve failure, the platform can be safely lowered using the backup hydraulic circuit. All [Internal Link: custom hydraulic systems] are equipped with pressure-compensated flow valves to maintain a steady descent speed of ≥3m/min, regardless of the load.

4. Safety and Access Features
To facilitate easy entry and exit, the 1800mm side of the platform is equipped with an integrated folding ladder . The railing system stands at 1100mm, featuring a swing-open gate for pallet loading. For maintenance safety, the system includes mechanical locking pins and hard-piping for all high-pressure lines to prevent hose-burst accidents. The entire unit is rated to IP56 protection, shielding electrical components from the high-pressure washdowns common in mining maintenance.

Proje Yürütme ve Başarılar

Uygulama Detayları

Uygulama ve Başarılar

For an underground mining enterprise in the Ruhr region, Germany, we delivered a Custom 6-Ton Vehicle-Mounted Scissor Lift with Hydraulic Protective Canopy, professionally tailored for complex and harsh underground mining working conditions. Replacing traditional fixed lifting equipment and risky manual high-altitude operation, this mobile high-lifting solution solves mining industry pain points including poor mobility, insufficient safety protection and low maintenance efficiency, realizing safe, flexible and efficient high-altitude operation for underground mine tunnels.
1. Mining-Grade Customization for Underground Harsh Conditions
Underground mining environments feature narrow tunnels, uneven road surfaces, falling rock risks and high dust density, which put forward ultra-high requirements for equipment mobility and safety. Ordinary aerial work platforms are unable to adapt to tunnel space constraints and impact risks. This customized 6-ton vehicle-mounted scissor lift integrates mobile chassis, heavy-duty scissor structure and automatic hydraulic canopy, fully complying with German underground mining safety standards and perfectly adapting to frequent moving and high-altitude maintenance operations in mine tunnels.
2. Mobile Lifting Operation Greatly Boosts Working Efficiency
Traditional underground high-altitude work relies on temporary scaffolding and fixed lifting devices, requiring repeated disassembly, assembly and position shifting with long operation cycles. The vehicle-mounted integrated design supports free tunnel movement and rapid positioning. The flexible lifting stroke and automatic hydraulic canopy opening and closing shorten preparation time greatly. It improves underground high-altitude operation efficiency by over 80%, effectively accelerating mine equipment maintenance, tunnel repair and daily inspection progress.
3. Hydraulic Protective Canopy Achieves Full Safety Protection
Falling gravel and rock fragments in mine tunnels easily cause equipment damage and personal injury, bringing major hidden dangers to high-altitude operation. The equipped hydraulic protective canopy realizes automatic synchronous lifting and closing, providing all-round anti-impact and anti-falling protection for operators and platforms. It achieves zero safety accidents caused by falling objects, comprehensively upgrading the safety level of underground high-altitude mining work.
4. Effective Labor Saving & Simplified Workflow
Traditional underground high-altitude maintenance requires multiple workers to cooperate in building temporary supports, positioning and safety monitoring, with high labor investment and low efficiency. This mobile scissor lift supports single-person independent driving and operation. It omits tedious temporary setup work, simplifies the overall operating process, and maintains efficient and continuous high-altitude operation.
5. Durable & Low-Failure Industrial Mining Design
Tailored for long-term high-intensity underground mining operation, the whole machine adopts thickened wear-resistant steel structure and dust-proof, explosion-proof and anti-corrosion treatments. Equipped with heavy-duty load protection, hydraulic self-locking and emergency stop devices, the equipment features strong terrain adaptability, stable heavy-load performance and low failure rate. It meets the long-term, high-frequency and high-strength operation requirements of underground mines.
Genel Proje Faydaları
After official put into use, the client’s underground mining high-altitude operation efficiency increased by 80%+, with greatly reduced labor costs and zero falling-object safety accidents. The entire tunnel maintenance and inspection process realized mobile, automated and safe operation, effectively improving mine operation efficiency and intrinsic safety level.
