Manufacturer-led approach
New systems, refurbishment, service and parts are reviewed within one engineering and manufacturing workflow.
KOŞU GRUP LIFTING SYSTEMS
Crane Major Maintenance & Overhaul
Structured overhaul for ageing or heavily used cranes, covering mechanical, electrical and load-path components according to condition and duty.
KOŞU GRUP TECHNICAL DECISION CENTRE
Clarify product selection, faults, refurbishment and technical enquiries in one flow.
Use short questions to reach the right product or service family and transfer the result into a technical enquiry. It provides verifiable preliminary engineering direction, not a final calculation.
01
Crane & hoist pre-selection engine
Use capacity, motion, duty, headroom and environment to identify the first product family.
02
From symptom to a safe technical route
Connects the symptom to the right service and part family without remote repair instructions.
03
Repair, overhaul, modernise or renew?
Prioritises the route using recurring faults, parts availability, control technology and changed process needs rather than age alone.
04
Prepare one structured technical enquiry
Turns the core data required for first review into one structured WhatsApp message.
SERVICE SCOPE
Crane Major Maintenance & Overhaul
Structured overhaul for ageing or heavily used cranes, covering mechanical, electrical and load-path components according to condition and duty.
Service scope is defined around system condition, site access, production schedule and intervention requirements. Required information, parts and equipment are prepared before field work so the application plan is clear.
WORKFLOW01Review equipment history and duty profile
02Assess hoist, travel and electrical groups
03Define critical parts and overhaul scope
04Functional checks and updated maintenance records
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.
Usage history, critical-component condition, brakes, gearboxes, couplings, runway/travel, electrical systems and remaining life are reviewed together.
Accurate Initial Data
Labels, capacity, photos, video and symptoms accelerate the first assessment.
Planned Intervention
Team and parts are planned around site, production and safety conditions.
Testing and Handover
Functional checks and user briefing are completed after the work.
FREQUENTLY 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.
