Global Industrial Crane Manufacturer & Heavy-Duty Lifting Solutions

Heavy industry requires uncompromising reliability, precise engineering, and maximum safety. As a global industrial crane manufacturer with more than 20,000 active projects across 53 countries, Sekizli Makine engineers and produces advanced lifting solutions for manufacturing plants, steel mills, shipyards, automotive facilities, logistics centers, energy plants, and heavy fabrication environments worldwide.

Our product range includes overhead cranes, double girder cranes, single girder cranes, gantry cranes, jib cranes, cabin cranes, automated cranes, special process cranes, lifting groups, electric load-carrying platforms, and crane spare parts. Each crane system is designed according to the facility layout, lifting capacity, operating frequency, environmental conditions, and required safety level.

We do not simply manufacture a standard crane. We design and produce integrated, custom-engineered lifting systems optimized for your facility’s specific load spectrum, operational cycle, structural dynamics, and production requirements.

Engineered for Heavy-Duty Performance

A crane used in a demanding industrial environment must provide more than basic lifting capability. It must maintain its structural integrity and operating precision throughout thousands of lifting, lowering, and travelling cycles.

For this reason, our heavy-duty crane systems are engineered with a focus on:

• High structural rigidity.
• Long service life.
• Controlled acceleration and deceleration.
• Reduced mechanical fatigue.
• Safe load positioning.
• Easy maintenance access.
• Reliable performance under intensive working conditions.
• Compatibility with modern automation and factory control systems.

Before production, every crane project is evaluated according to its intended duty class, lifting capacity, span, lifting height, travelling distance, average operating time, load distribution, and environmental conditions.

Uncompromising Engineering: FEM 2m / ISO M5 Standards

In the global crane market, minimizing initial capital expenditure can sometimes lead to the procurement of light-duty FEM 1Am systems for applications that actually require a higher duty classification. Although this approach may reduce the initial crane price, it can result in accelerated mechanical fatigue, increased maintenance requirements, reduced availability, and a shorter operational lifespan.

To ensure maximum durability and structural integrity under intensive operating conditions, our heavy-duty industrial cranes are strictly engineered according to FEM 2m and ISO M5 classifications, where applicable to the project requirements.

Selecting the correct FEM and ISO classification is one of the most important decisions when evaluating an industrial crane. The correct classification depends on:

• Average daily operating time.
• Number of lifting cycles.
• Load spectrum.
• Frequency of full-capacity lifting.
• Acceleration and braking conditions.
• Required production continuity.
• Environmental and structural conditions.

A lower initial crane price does not always represent a lower total cost of ownership. A crane with an unsuitable duty classification may cause higher costs through unplanned downtime, component replacement, production interruptions, and frequent maintenance.

Advanced Kinematics and Precise Motion Control

All lifting and travelling groups can be equipped with closed-loop Vector Frequency Drive systems. These VFD controls enable smooth and precise movement across all crane axes, including:

• Hoisting.
• Cross travel.
• Long travel.
• Trolley movement.
• Special process positioning.

By controlling motor speed and torque, the system reduces sudden movements, mechanical shocks, and unnecessary stress on the crane structure. Operators can position loads with millimeter-level precision, which is especially important in steel processing, mold handling, machinery installation, shipbuilding, and precision manufacturing applications.

Controlled acceleration and deceleration also improve operator comfort, reduce load oscillation, and help protect motors, gearboxes, wheels, rails, and brakes from excessive wear.

Anti-Sway Technology for Safer Operations

Load swing can reduce productivity and create serious safety risks in high-speed crane operations. Our PLC-based electronic anti-sway technology actively controls pendulum movements during lifting and travelling operations.

The anti-sway system helps:

• Reduce load oscillation.
• Improve positioning accuracy.
• Shorten handling times.
• Protect nearby equipment and structures.
• Support safer operation in high-cycle applications.
• Improve the performance of semi-automated and fully automated crane systems.

Anti-sway functionality can be integrated into overhead cranes, gantry cranes, cabin cranes, automated cranes, and special process crane applications according to the required control architecture.

Dynamic Braking for High-Inertia Applications

Heavy-duty crane systems require dependable braking performance, particularly when handling high-capacity loads or operating at high travelling speeds.

For demanding applications, electro-hydraulic Eldro thruster brakes can be used to provide reliable and controlled stopping performance. These braking systems help reduce:

• Mechanical impact during stops.
• Excessive wheel and rail loads.
• Brake shoe wear.
• Uncontrolled load movement.
• Risks associated with high-inertia braking.

The braking configuration is selected according to the crane capacity, operating speed, duty classification, load characteristics, and required stopping distance.

Overhead Crane Systems

Overhead cranes, also known as bridge cranes, are designed for indoor industrial facilities where efficient use of floor space and reliable material handling are essential.

Our overhead crane portfolio includes:

• Single girder overhead cranes.
• Double girder overhead cranes.
• Standard bridge cranes.
• Heavy-duty production cranes.
• Cabin-operated cranes.
• Automated overhead cranes.
• Special process overhead cranes.
• Monorail crane systems.
• Mobile lifting groups.

Single girder cranes are often preferred for lower and medium-capacity lifting applications where a lightweight and economical structure is required. Double girder cranes are suitable for higher capacities, larger spans, greater lifting heights, and more intensive operating cycles.

Our overhead crane structures can be engineered with a deflection tolerance of up to L/1000, depending on project requirements and the applicable design criteria. This helps maintain structural rigidity across wide spans and supports precise load handling in demanding environments.

Double Girder Cranes

Double girder cranes are designed for heavy-duty lifting operations requiring high capacity, long spans, high lifting heights, or frequent full-load cycles.

Typical applications include:

• Steel mills.
• Foundries.
• Heavy machinery plants.
• Shipyards.
• Precast concrete facilities.
• Energy and power plants.
• Automotive manufacturing.
• Large-scale fabrication halls.
• Industrial warehouses.

A double girder crane can be configured with top-running or underslung arrangements, cabin operation, remote control, automated positioning, special lifting attachments, and multiple hoisting mechanisms.

The final crane design is determined by the required capacity, span, lift height, duty class, rail arrangement, building structure, and production process.

Gantry Crane Systems

Gantry cranes are highly stable lifting systems designed for outdoor yards, logistics areas, construction sites, shipyards, steel stockyards, and open-air production facilities.

Our gantry crane systems can be engineered for:

• Extreme wind loads.
• Outdoor exposure.
• Maritime environments.
• Corrosive atmospheres.
• Large outdoor spans.
• Heavy steel and concrete handling.
• Loading and unloading operations.
• Container and material storage yards.

Depending on the application, gantry cranes can be manufactured as:

• Full gantry cranes.
• Semi-gantry cranes.
• Single girder gantry cranes.
• Double girder gantry cranes.
• Non-protruding gantry cranes.
• Cantilever gantry cranes.
• Cabin-operated gantry cranes.
• Automated gantry cranes.

Weather-resistant surface treatments, electrical protection, wind monitoring, rail clamps, storm brakes, and controlled travelling systems can be integrated into the crane design for outdoor operation.

Jib Cranes and Special Process Cranes

Jib cranes provide localized lifting capability in production cells, maintenance areas, assembly lines, workshops, and loading zones. They are useful where a full overhead crane system is not necessary or where a dedicated workstation crane is required.

Special process cranes are designed for operations that involve unusual loads, restricted spaces, repetitive handling, or specific production sequences. These systems may include:

• Console cranes.
• Slewing cranes with 360-degree trolley movement.
• Automated cranes.
• Ex-proof pneumatic cranes.
• Shaft-mounted cranes.
• Automated mobile cranes.
• Cabin cranes.
• Crane systems with customized lifting attachments.

For hazardous environments, explosion-protected components and suitable electrical or pneumatic equipment can be selected according to the area classification and process requirements.

Automated Crane Solutions

Modern manufacturing facilities increasingly require automated material handling systems that can operate with high repeatability and minimal operator intervention.

Our automated crane solutions can support:

• Programmable load positioning.
• Automatic route selection.
• Defined storage locations.
• Integration with production lines.
• Warehouse management systems.
• PLC and SCADA communication.
• Remote diagnostics.
• Collision prevention.
• Load monitoring.
• Automated cycle management.

Automated crane systems are particularly beneficial in repetitive production environments, high-risk areas, high-temperature processes, and facilities where consistent positioning accuracy is critical.

Crane Price and Project Cost

The crane price of an industrial lifting system cannot be determined accurately from lifting capacity alone. A reliable quotation must consider the complete technical configuration and the operating conditions of the facility.

The main factors affecting industrial crane price include:

• Crane type.
• Lifting capacity.
• Span.
• Lifting height.
• Travelling distance.
• Duty classification.
• FEM and ISO requirements.
• Single or double girder configuration.
• Hoist and trolley type.
• Motor and gearbox specifications.
• VFD and control system.
• Anti-sway technology.
• Brake configuration.
• Cabin or remote control.
• Automation requirements.
• Indoor or outdoor operation.
• Wind and environmental conditions.
• Explosion protection requirements.
• Special lifting attachments.
• Installation and commissioning.
• Structural modifications.
• Testing and certification.
• Spare parts and after-sales service.

For this reason, a low crane price based on a simplified specification may not provide the required performance for a heavy-duty application. We evaluate each project according to its total operational requirements and provide a detailed, application-specific proposal.

Our engineering team can prepare a crane price and technical offer based on the following project information:

• Required lifting capacity.
• Maximum and minimum load weights.
• Building span and runway dimensions.
• Required lifting height.
• Crane travelling distance.
• Daily operating hours.
• Number of lifting cycles.
• Load spectrum.
• Indoor or outdoor installation.
• Existing runway or structural details.
• Required control method.
• Delivery location.
• Installation and commissioning requirements.

Crane Spare Parts and Service Support

Long-term crane performance depends not only on the original design but also on timely maintenance and the availability of compatible spare parts.

Our crane spare parts portfolio includes:

• Crane wheels.
• Eldro brakes.
• Electromagnetic brakes.
• Collision sensors.
