Ports & Terminals
Keeping global trade moving.
From ship-to-shore cranes to RTGs and reach stackers — ELS supports port and terminal operators with repair, spare parts, lifecycle extensions, and precision machining. Headquartered in Rotterdam, we understand port operations inside and out.
Engineering for Port Operations
Maximising uptime in 24/7 environments
Ports never sleep — and neither does the pressure on your equipment. STS cranes, RTGs, and spreader systems operate under extreme duty cycles, salt spray corrosion, and constant load variation. ELS provides the engineering support that keeps your terminal running.
All brands, all vintages
Whether you operate Liebherr, Kalmar, ZPMC, Konecranes, or legacy Nelcon and Fantuzzi equipment, our engineers have the experience to service and repair your fleet. We are not tied to any OEM, which means unbiased advice and competitive pricing.
Our Rotterdam headquarters gives us direct access to Europe's busiest port cluster, while our China office ensures cost-effective manufacturing and quality-controlled spare parts supply from Asian production facilities.
From emergency breakdown support to multi-year lifecycle extension programmes, ELS is a single partner for all your port equipment engineering needs — covering mechanical, electrical, structural, and hydraulic systems.

STS & RTG Crane Expertise
Ship-to-shore and rubber-tyred gantry cranes are the backbone of container terminal operations. ELS engineers specialise in the complete mechanical and electrical systems of these machines — from hoist gearboxes and trolley drives to spreader mechanisms and anti-sway systems.
We carry out on-site repairs, component refurbishment, spare parts supply, and full modernisation projects including control system upgrades and electrification of diesel-powered RTGs.

Equipment We Support in Ports & Terminals
ELS provides technical support for a wide range of port and terminal equipment. Whether the equipment is still fully supported by the OEM, partly obsolete or already in a later lifecycle phase, ELS helps define the right technical and commercial solution for its current condition.
Typical Terminal Challenges We Solve
Obsolete or difficult-to-source parts
Older terminal equipment often contains components that are no longer easily available, have long lead times or no longer match the commercial reality of the machine. ELS helps identify reliable alternatives, refurbished options or custom-manufactured replacements.
Electrical and control system issues
Failures in control systems, drive components, sensors, PLCs, safety systems or operator interfaces can have a direct impact on terminal availability. ELS supports troubleshooting, replacement, repair and upgrade paths for electrical and control-related issues.
Mechanical wear and structural ageing
Heavy-duty components such as crane wheels, cable sheaves, gearboxes, slewing rings, drums, shafts, bearings and structural parts are exposed to continuous stress. We support inspection, reverse engineering, refurbishment and replacement of critical components.
Downtime during operations
When equipment is out of service, speed and technical clarity matter. ELS can assist with emergency spare parts, technical assessment, repair planning and practical alternatives to reduce unnecessary waiting time.

Port Crane Modernisation & Upgrades
Modernisation does not always mean replacing the complete machine. In many cases, targeted upgrades can extend the operational value of existing equipment and improve reliability, safety or maintainability.
Our approach is practical: we look at the age, duty cycle, machine value and operational role of the equipment before defining the most suitable upgrade path.

- Control system upgrades
- Drive and power system improvements
- SLI / LMI and safety system upgrades
- Operator assistance and visibility systems
- Electrical cabinet renewal
- Sensor and encoder replacement
- RTG electrification support
- Mechanical modifications and component improvements
- Replacement of outdated assemblies with modern alternatives

Reverse Engineering & Machining for Terminal Components
When drawings are missing, components are discontinued or OEM pricing is no longer realistic, reverse engineering can be a strong alternative.
ELS supports the complete process from technical definition to manufactured component.
Typical port and terminal components include crane wheels, cable sheaves, shafts, bearing housings, bronze bushes, gear parts, cable drums, brackets, construction parts and custom machine components.
- On-site measurement or 3D scanning
- Technical assessment of the existing part
- CAD modelling and drawing creation
- Material and tolerance definition
- Manufacturing through selected partners
- Quality control and documentation
- Delivery of finished components ready for installation

Component Repair & Refurbishment
Not every component needs to be replaced. In many cases, refurbishment can restore function, reduce cost and shorten lead time. Where possible, we combine repair with technical improvement, so the component returns not only functional, but better aligned with the machine’s current operating conditions.

- Slewing rings and related parts
- Drive wheels and bearings
- Electrical modules and control components
- Mechanical assemblies and fabricated parts

Strategic Parts Supply for Terminal Fleets
For port operators, spare parts availability is a strategic uptime factor. ELS helps terminals secure parts for mixed fleets, older equipment and machines where standard sourcing is no longer sufficient. Our focus is not only on finding a part number. We look at technical fit, machine condition, operating environment and the most sensible lifecycle solution.
We supply and source:
We supply and source:
- Electrical components
- Control system parts
- Drives, motors and brakes
- Crane wheels and bearings
- Cable sheaves and cable drums
- Steel wire ropes and rope-related parts
- Slip rings and current collectors
- Joysticks, encoders and sensors
- Gearboxes and couplings
- Hydraulic components
- Spreaders and lifting components
- Custom machined parts
Why Terminal Operators Work With ELS
01
Lifecycle thinking
We do not only look at the immediate failure. We look at the role of the machine, its age, the future use of the fleet and the most realistic path to keep it operational.
02
Independent technical support
ELS is not tied to one brand or one supply route. That allows us to compare options and advise based on technical suitability, availability and total cost.
03
Engineering plus supply
We combine practical field service with engineering, sourcing, manufacturing and refurbishment. This gives terminal operators one partner for both analysis and execution.
04
Support for older and mixed fleets
Many terminals operate equipment from different brands and generations. ELS helps maintain continuity across this mixed technical landscape.
05
International reach
With a base in the Netherlands and access to selected international manufacturing and supply partners, ELS supports terminal operators with both European engineering standards and global sourcing flexibility.
Example Applications
01
RTG control system support
A terminal operates several RTG cranes with ageing control components and increasing electrical failures. ELS can inspect the system, define critical components, propose replacement options and support a phased upgrade to improve reliability without replacing the full crane.
02
STS crane component replacement
A critical mechanical component on an STS crane is no longer available within the required lead time. ELS can measure or scan the original part, create technical drawings, define material requirements and manage manufacturing through selected partners.
03
Reach stacker parts alternative
A reach stacker requires an expensive or long-lead OEM component. ELS can review the application, compare available alternatives and supply a technically suitable replacement aligned with the machine’s age and usage.
04
Terminal fleet lifecycle review
A terminal wants to reduce unexpected downtime across a mixed fleet of cranes and handling equipment. ELS can help identify high-risk components, obsolete systems and practical upgrade opportunities, creating a focused lifecycle action plan.
05
SLI / LMI service & troubleshooting
A terminal crane, reach stacker or other lifting machine is experiencing recurring SLI / LMI faults, incorrect load readings, sensor errors or safety-related warnings. ELS can inspect the system, trace the fault to sensor, wiring, display, controller, load cell or calibration level, and define the most practical solution. Where required, we support troubleshooting, component replacement, system calibration and upgrade options to restore safe, reliable operation and reduce repeat failures.
