Project Background
Client: Major automotive service center in Moscow, Russia
Core Challenge:
Manual handling of heavy engine blocks, transmissions, and chassis components caused workflow bottlenecks (avg. 45-min delay per repair job) and safety risks.
The existing chain cranes lack accuracy in lifting parts (such as electric vehicle battery packs), which subsequently leads to equipment damage.
The harsh Russian winter (with temperatures dropping to minus 25 degrees Celsius) causes the ordinary crane lubricants to freeze, thus resulting in equipment shutdown.
Solution Objective:
Deploy a 5T Overhead Bridge Crane with cold-optimized components to streamline automotive repair operations. Technical specifications:
| Parameter | Value | Rationale |
| Capacity | 5tons | Handles engines, transmissions, and EV batteries |
| Span | 20m | Covers dual vehicle bays + parts storage |
| Lifting Height | 10m | Clears hydraulic lifts and stacked inventory |
| Duty Class | M3-M8 (moderate to heavy) | Supports 16-hr/day operation |
| Hoist Mechanism | Wire rope hoist | Precise vertical control (±2mm) |
Power Supply | 380V/50Hz/3Ph | Matches Russian industrial grid |
| Control System | Pendant + wireless remote | Operator mobility in confined spaces |
The Features Of Sinoko Bridge Cranes
Automotive Repair-Specific Engineering
Cold-resistant wire rope hoist:
It uses steel cables resistant to severe cold (-30°C). This prevents the cables from freezing and breaking. The surface is also coated with an anti-icing layer to prevent moisture absorption.
Dual braking system (mechanical braking + electromagnetic braking) ensures the safety of the load in case of power failure.
Thermal compensation runway beam:
It uses low-alloy steel beams and is equipped with expansion joints, which can adapt to temperature changes ranging from -25°C to +40°C and prevent track misalignment.
Precision Load Positioning:
VFD-controlled hoisting (0.05–8 m/min speed range) enables millimeter-accurate placement of delicate components (e.g., sensors, hybrid powertrains).
Space-Optimized Design:
Low-headroom trolley maximizes vertical clearance (10m lift height in 12m-tall workshop).
Collision avoidance sensors detect overhead obstacles (e.g., lighting rigs, ventilation ducts).
Implementation Process
From design to installation and commissioning, the Sinoko cranes took a total of one and a half months. Below is a detailed introduction to the construction process.
Phase 1: Design & Site Adaptation
Challenge | Solution |
| Limited structural headroom | Engineered compact girder profile (height: 450mm) |
| -25°C winter hardening | Specified Arctic-grade lubricants (ISO VG 32) |
| Voltage fluctuations (360–410V) | Installed voltage stabilizers (±5% tolerance) |
Phase 2: Installation & Commissioning
Structural Assembly:
Bolt-free splice connections between runway beams ensured rigidity in temperature swings.
Electrical Integration:
IP55-rated enclosures protected components from dust/oil mist.
Performance Validation:
6.25T load test (125% capacity) with ≤3mm girder deflection.
Cold-start test at -20°C: Hoist response time <2 seconds.
Staff Training:
Russian-language VR simulations for emergency procedures and maintenance.
Project Outcomes
After the customer had used the Sinoko crane for one year, the company specially sent an engineer to visit the customer again. During the conversation with the customer, we found that this crane had greatly eased their work.
Operational Performance Metrics
KPI | Pre-Install | Post-Install | Improvement |
| Component handling time | 18 min | 6 min | -67% |
| Equipment damage incidents | 4/month | 0 | 100% reduction |
| Energy consumption | 2.1 kWh/cycle | 1.5 kWh/cycle | -29% |
| Downtime (winter) | 12 days/yr | 0.5 days/yr | -96% |
Strategic Benefits
Safety: Compliance with GOST R ISO 12485-2013 (Russian crane safety standards).
ROI: 11-month payback via reduced labor costs ($78k/yr saved).
Capacity: Throughput increased to 32 vehicles/day (previously 22).
Application Areas
In addition, this crane can also be used in the following fields:
| Industry | Use Case | Technical Adaptation |
| Aerospace MRO | Aircraft component handling | Cleanroom-compatible enclosed hoist |
| Heavy Equipment | Mining machinery maintenance | M8 duty rating for continuous cycles |
| Warehousing | Spare parts logistics | 20m span covering 800m² floor area |
Key Achievement: The Overhead crane's thermo-synchronous control system automatically adjusts hoist speed in sub-zero conditions, preventing cable slippage during critical lifts. This resulted in zero cold-weather failures in two winter seasons,Sinoko Crane has won the trust of customers through its outstanding technology, prompting orders from 3 additional service centers in St. Petersburg.
This Workshop Bridge Crane, customized by a Russian client, has a lifting capacity of 5 tons. The Sinoko crane can lift up to 500 tons at its maximum and as low as 0.5 tons at its minimum. We can specially customize it according to the materials you need to carry.
