Reliable and Controlled Power Transmission for Heavy Loads

At AYDINLAR DISLI & MAKINA and AYMAK CELIK, we manufacture gearboxes, scrap grabs, attachments, and mechanical spare parts for crane and lifting systems used in heavy-industrial and port facilities.

We engineer crane-system equipment by considering the load to be lifted, duty class, lifting speed, motor power, output torque, braking loads, start-stop frequency, reversing duty, and impact loads.

OUR PRODUCTS AND EQUIPMENT

• Ladle-crane gearboxes
• Scrap grabs and attachments
• Port-crane hoisting gearboxes

LADLE-CRANE GEARBOXES
Ladle-crane gearboxes are designed for high temperatures, heavy dust, high loads, and impact-duty operating conditions. Gears, shafts, bearings, housings, and connection components are evaluated as an integrated system to ensure reliable hoisting operation.

• Ladle-crane hoisting gearboxes
• Application-specific gear and pinion sets
• Gearbox input and output shafts
• Gearbox housings and covers
• Motor and gearbox couplings
• Mechanical connection and bearing-support components
• Spare parts compatible with existing gearboxes

SCRAP GRABS AND ATTACHMENTS
Scrap grabs, also known as orange-peel grabs, are manufactured for lifting, handling, and discharging scrap metal under heavy-duty operating conditions.

• Scrap grabs
• Grab-jaw assemblies
• Grab bodies
• Pins, bushes, and connection components
• Mechanical opening and closing components
• Grab lifting and connection attachments
• Remanufacturing of worn components
• Maintenance and overhaul services

PORT-CRANE HOISTING GEARBOXES
Port-crane hoisting gearboxes are engineered by considering high lifting capacities, intensive duty cycles, variable loads, and demanding environmental conditions.

• Port-crane hoisting gearboxes
• Gear sets for hoisting systems
• Input and output shafts
• Motor and drum couplings
• Gearbox housing and cover components
• Mechanical spare parts compatible with existing systems

MAINTENANCE, OVERHAUL, AND MODERNISATION

• Controlled gearbox disassembly and damage assessment
• Inspection of gear-tooth contact patterns and backlash
• Inspection of shafts, bearings, and bearing seats
• Inspection of housings, covers, and mating surfaces
• Remanufacturing of damaged or worn components
• Controlled assembly and adjustment
• No-load operational and functional testing
• Capacity upgrades and modernisation of existing systems

REVERSE ENGINEERING AND SPARE-PARTS MANUFACTURING
Components of crane gearboxes and mechanical equipment for which technical drawings or spare parts are unavailable are precisely measured to prepare three-dimensional models and manufacturing drawings.

• Precision measurement of existing components
• Creation of three-dimensional models and manufacturing drawings
• Determination of material and heat-treatment specifications
• Calculation of gear geometry and backlash
• Remanufacturing of gears, pinions, shafts, couplings, pins, and bushes
• Manufacturing of critical spare parts compatible with existing systems

OUR ENGINEERING AND MANUFACTURING APPROACH
In gear and gearbox design, tooth-flank strength, tooth-root stresses, contact ratio, backlash, shaft deflection, bearing loads, and housing strength are evaluated as an integrated system. KISSsoft calculations, bearing-life analyses, and finite element analysis are used to verify the operating performance of critical components before manufacturing.

Our manufacturing processes include appropriate material selection, heat treatment, precision machining, gear cutting and grinding, dimensional quality control, and controlled assembly.

Our objective is to provide reliable, maintainable, and long-service-life power-transmission solutions that operate safely under the high loads and demanding duty conditions of crane and lifting systems.
