Manufacturer-led approach
New systems, refurbishment, service and parts are reviewed within one engineering and manufacturing workflow.
SPARE-PART IDENTIFICATION + 24/7 SERVICE
Crane Electrical Panel & Contactors
Safe data collection for contactor, overload relay, fuse, relay, drive and control-transformer faults.
01
Identity and matching
Part name alone is not a decision. Nameplate, dimensions, voltage, connector/interface and equipment data are checked together.
Explore technical path 02Dimensions and duty
Mechanical dimensions, electrical rating and operating conditions are core compatibility inputs.
Explore technical path 03Alternative route
If the original part is unavailable, refurbishment, adaptation or manufacture is considered only after technical compatibility is verified.
Explore technical path 04Installation and function
After replacing safety or motion components, adjustment and functional checks should be performed by competent technical personnel.

DESCRIBE THE REQUIREMENT CLEARLY
The same requirement may be described in different terms.
These phrases may describe the same technical requirement. Relevant links lead to the most useful selection, pricing, service, parts or fault page.
Supply, motor power, contactor/VFD, safety circuit, control voltage and schematic define matching.
What may these symptoms indicate?
- Main contactor does not engage
- Single-phase or one-direction failure
- Repeated overload or fuse trip
- Heat, noise or odour inside the panel
Before service arrives
- Only competent electrical personnel may open the panel.
- Apply isolation and lockout procedures.
- Do not re-energize visibly burnt components.

ExploreFREQUENTLY ASKED QUESTIONS
Short answers specific to this page context.
01What information is required for a crane or hoist quotation?+
Maximum load, lifting height, horizontal travel, span, operating frequency, power supply, site photographs and installation location help determine the correct system.
02Can a quotation be prepared without a site survey?+
A preliminary quotation can be prepared from basic data. A site survey is recommended when the supporting structure, runway, floor, power or installation conditions affect the project.
03Do you provide maintenance and repair for existing cranes?+
The scope is technically reviewed after receiving the system type, capacity, brand/model, fault symptoms and site location.
04How are spare parts matched?+
Labels, serial data, capacity, photographs, dimensions and connection details are used to identify a suitable part.
05Do you support projects across Türkiye?+
Manufacturing and service coordination from Istanbul is planned across Türkiye according to project scope, schedule and location.
06Does Koşu Grup serve all of Türkiye?+
Yes. Project data can be collected remotely, while manufacturing, shipping, installation and service are planned nationwide according to scope and site conditions.
07Does Koşu Grup manufacture for international projects?+
International manufacturing and project enquiries are accepted. Country, power supply, site dimensions, delivery model, installation and documentation are clarified during quotation.
08Do calculator results constitute engineering approval?+
No. The tools prepare enquiry data. Capacity, structure, duty class, dynamic effects and safety require authorised engineering verification.
09What faults are covered by 24/7 technical service?+
Initial assessment and service coordination cover hoists, bridge and gantry cranes, controls, brakes, limits, motors, travel, power feeds, chain/rope and spare-part faults.
10Which photos help an RFQ?+
Equipment labels, full system, runway/beam, hook area, panel, pendant, fault point and safe-distance site views accelerate assessment.
11How is crane maintenance frequency defined?+
Manufacturer instructions, use intensity, environment, load spectrum, fault history and legal requirements are reviewed together.
12Can an old crane be modernised?+
A scope can be defined after reviewing structure, mechanics, brakes, limits, controls, motors, gearboxes, power supply and spares availability.
13How are spare parts identified?+
Make/model, serial and capacity labels, dimensions, connectors, mounting, photos and existing part codes are compared together.
CONTROL PANEL & CONTACTORS
Crane panel parts are matched by circuit function, coil voltage, motor duty and protection interface.
A contactor that looks identical may have a different coil, utilisation category, auxiliary contact arrangement or current rating. For control-panel service or parts, share schematic/reference data where available, coil/control voltage, motor information, clear photos and the actual fault symptom.
Confirm coil/control supply before matching.
Motor power/current and duty influence switching components.
Limits, emergency stop, brake and VFD/relay interfaces must remain coordinated.
Prepare panel/contactor enquiryPreliminary guidance does not replace engineering verification; equipment and site data are confirmed for the project.
