نظرة عامة على العميل

This technical deployment involved the engineering, structural integration, and commissioning of twin 3D wall-mounted scissor man lifts for a heavy-duty machinery manufacturer located in the Dinh Vu Industrial Zone, Hai Phong, Vietnam. The facility specializes in the surface treatment and protective coating of large-scale construction equipment and maritime components. To ensure uniform coverage and operator safety during high-access painting tasks, the facility required a 3D movement solution capable of longitudinal (X-axis), vertical (Y-axis), and lateral extension (Z-axis) travel.

هذا 3D man lift platform was specifically customized to integrate with the existing spray booth infrastructure, ensuring full access to complex geometries while strictly adhering to international ATEX explosion-proof safety standards for hazardous painting environments. The deployment enables two operators to work independently on opposite sides of the workpiece, significantly increasing throughput and reducing the manual positioning time required for large-scale industrial coating applications in the Vietnamese manufacturing sector.

التحدي والحل

تحديات العميل

The industrial coating facility in Hai Phong faced several engineering and safety bottlenecks that compromised both production efficiency and workplace safety. Standard floor-based lifting equipment was unsuitable for the restricted space and hazardous conditions of the specialized spray booth.

  • Hazardous Atmospheric Constraints: The presence of volatile organic compounds (VOCs) and flammable paint mists created an explosive environment. Any standard electrical motor or sparking component in a pneumatic man lift would pose an immediate fire hazard, requiring a system that meets IECEx hazardous area classifications.

  • Spatial and Airflow Interference: Conventional mobile scissor lifts occupied critical floor space, obstructing the downdraft ventilation system and creating “shadow areas” where paint could not be applied uniformly. The client required a solution that kept the floor 100% clear.

  • Complex Geometric Access: Large-scale maritime components feature deep recesses and varying heights. Manual scaffolding proved slow and dangerous, while standard 2D wall lifts could not provide the necessary lateral extension (Z-axis) to reach the center of the workpieces.

  • Structural Stability in 3D Motion: Extending a 300kg platform via a scissor arm while the base moves vertically and longitudinally induces significant torque on the wall-mounted rails. Any structural deflection would lead to platform oscillation, compromising the precision of the spray application.

  • Environmental Degradation and Maintenance: Hai Phong’s high coastal humidity, combined with constant paint overspray, threatened to clog hydraulic seals and corrode standard steel surfaces, leading to frequent unplanned downtime of the wall-mounted lift system.

الحل المخصص لـ GRADIN

The implementation centered on a high-rigidity, wall-guided kinematic system consisting of three independent axes of motion. The structure was engineered to provide a 100% floor-clearance footprint.

1. 3-Axis (3D) Kinematic Architecture
The platform’s mobility is divided into three coordinated vectors. Longitudinal travel (X-axis) is managed via heavy-duty wall-mounted rails that span the length of the booth. Vertical elevation (Y-axis) utilizes a reinforced mast with synchronized Internal Link: heavy-duty lift chains. Lateral extension (Z-axis) is achieved through a multi-stage hydraulic scissor mechanism, allowing the operator to extend the cage from the wall directly toward the workpiece. This 3D reach ensures that even the most complex top-surfaces and recessed areas of machinery are accessible.

2. Explosion-Proof (Ex-rated) Engineering
Given the VOC-heavy environment in the Hai Phong facility, all electrical and hydraulic components carry External Link: ATEX Zone 1/Zone 2 explosion-proof certification. The system employs spark-resistant bronze-coated rollers and flame-proof motor enclosures to eliminate ignition sources. The centralized control cabinet is mounted outside the spray booth, while an IP65-rated, Ex-d control interface is located inside the operator cage, allowing for real-time adjustment of X, Y, and Z coordinates.

3. Structural Rigidity and Counter-Torque Design
To manage the significant torque induced when the scissor arm is at full Z-axis extension, the wall-mounted carriage utilizes high-tensile 20# channel steel. Precision-machined guide rollers with double-shielded bearings ensure smooth vertical travel along the mast. This Internal Link: 3D man lift configuration minimizes structural vibration at height, ensuring that the operator remains stable even during the high-pressure application of heavy industrial coatings.

4. Integrated Safety and Ergonomics
The operator cage is equipped with a non-slip chequered plate floor and 1100mm perimeter railings. Safety features include:

  • Velocity-Sensing Burst Valves: Installed directly on the hydraulic cylinders to prevent uncontrolled descent in the event of a hose failure.

  • Integrated Work Lighting: 24V LED explosion-proof lamps mounted on the cage to improve visibility in dark recesses.

  • Pneumatic Air Interface: Built-in air supply lines within the scissor arms to power the operator’s spray equipment directly from the platform.

تفاصيل التنفيذ

التنفيذ والإنجازات

For an industrial manufacturing client in Vietnam, we customized a 300kg 3D Wall-Mounted Scissor Man Lift, exclusively tailored for narrow-space operation of industrial spray booths. Replacing traditional ladder and temporary scaffolding working modes, this professional wall-mounted lifting solution solves the pain points of low efficiency, poor safety and uneven spraying quality in high-altitude spraying operations, bringing comprehensive upgrades to the client’s spraying production process.
1. Optimized for Spray Booth Narrow Space
Traditional mobile lifting equipment occupies large floor space and cannot adapt to the compact layout of standard spray booths, while ladders and scaffolds limit flexible operation. The customized wall-mounted 3D scissor structure requires no ground occupation, saving valuable spray booth space. It supports multi-directional three-dimensional adjustment of height and horizontal position, covering all spraying dead zones of workpieces, and fully adapts to the closed and narrow working environment of Vietnamese industrial spray booths.
2. Improved Spraying Efficiency & Uniform Quality
Manual high-altitude spraying with ladders causes unstable operation, repeated spraying and missing spraying, leading to ununiform paint finish and low working speed. The stable lifting platform provides staff with a fixed and flexible working position. It realizes close-distance and full-coverage spraying, increasing overall spraying efficiency by over 70% and effectively improving the flatness and uniformity of the paint surface, greatly reducing defective products caused by manual operation errors.
3. Enhanced On-Site Operation Safety
Spray booths are flammable and confined working areas, where traditional ladder operations carry high risks of slipping, falling and accidental collisions. This customized man lift is equipped with anti-slip platform, limit height protection and emergency stop device, meeting Vietnam industrial safety and spray booth fire-proof and safety specifications. It eliminates high-altitude operation risks and creates a standardized safe working environment.
4. Labor Saving & Easy Operation
The original high-altitude spraying work requires multiple workers to cooperate with positioning and auxiliary support. The 3D adjustable wall-mounted lift supports عملية مستقلة لشخص واحد مستقل, simplifying the working process, reducing labor investment, and avoiding time wasted on frequent moving and building temporary tools, realizing continuous and efficient spraying operation.
5. Professional Custom Working Condition Adaptation
Aiming at the dust-filled and slightly corrosive working environment of spray booths, the equipment adopts anti-rust and anti-paint adhesion surface treatment. The 300kg rated load perfectly matches the weight of staff and spraying tools. The precise 3D moving function solves the problem of difficult fine positioning of traditional lifting equipment, fully matching the refined spraying processing needs.
الفوائد الإجمالية للمشروع
After putting into use, the client’s spray booth operation realizes standardized high-altitude intelligent operation. It achieves 70%+ efficiency improvement, greatly reduced defective rate and hidden safety hazards, stable spraying quality, and effectively improves the overall production grade and market competitiveness of factory products.
