A systematic approach to identify failure risks and manage equipment wear.
Our expertise
Your conveyor is a critical link in production.
In mines, quarries, cement plants and processing facilities, conveyors provide continuous material transport. A belt, idler, pulley or drive failure can disrupt the entire production chain.
NISAN CORPORATION follows a structured approach: system inspection, identification of defects, corrective action planning, site-specific intervention and post-maintenance verification.
- Belt condition inspection
- Idler and pulley inspection
- Alignment checks
- Drive system checks
- Failure cause investigation
- Technical service report
Our services
Targeted maintenance for critical components.
Our services are defined according to conveyor configuration, operating conditions, access constraints and the client’s production requirements.
02
Idlers and idler stations
Checks for rotation, noise, play, bearing condition and material buildup. Replacement of defective components to specification.
03
Pulleys and belt cleaners
Inspection of pulleys, lagging, belt scrapers, cleaning devices and belt contact areas.
04
Motors and drive systems
Mechanical inspection of gearboxes, couplings, transmissions and supports. Visual motor checks and coordination of required electrical inspections.
05
Alignment and tensioning
Investigation of belt mistracking, inspection of idler stations and verification of tensioning devices according to conveyor design.
06
Mechanical repairs
Repairs to accessible components, replacement of worn parts and rehabilitation support in accordance with site procedures.
A complete system perspective
Components must be assessed together to understand the origin of faults.
Inspection points
Every component matters.
A useful inspection goes beyond the belt. It considers interactions between mechanical components, supporting structures and operating conditions.
01
Structure and supports
Visual checks of supports, fasteners, deformation, corrosion and access conditions.
02
Bearings and bearing housings
Checks for abnormal noise, apparent overheating, excessive play or lubricant leakage.
03
Drive and gearbox
Inspection of fasteners, couplings, leaks and visible defects, with additional checks as required by applicable procedures.
04
Safety devices
Visual inspection of guards, emergency stops and safety devices within the authorized scope.
Failure diagnostics
Identify warning signs before they become major shutdowns.
Symptoms must be confirmed by inspection and analyzed in context. The same issue can have several possible causes.
Belt mistracking
Check idler alignment, loading conditions, material buildup and pulley condition.
Abnormal wear
Inspect friction areas, scrapers, seized idlers and loading conditions.
Vibration and noise
Investigate loose fasteners, bearing defects or drive system problems.
Slippage or jamming
Check traction conditions, belt tension, obstructions and drive components.
Our method
A structured intervention, from diagnosis to reporting.
Each intervention is planned around the site, conveyor type, identified risks, available parts and required permits.
Arrange an assessment →Requirement assessment
Collection of available information: conveyor type, symptoms, operating conditions, failure history and production constraints.
Inspection and safety preparation
Site assessment, risk analysis, scope definition and application of site isolation and permit procedures.
Diagnosis and action plan
Identification of observed defects, determination of required actions and confirmation of resources, parts and timing.
Maintenance and repair
Execution of authorized work according to approved methods, manufacturer instructions and applicable HSE requirements.
Verification and reporting
Post-maintenance checks, closure of applicable findings, equipment handover subject to site authorization and reporting of observations.
Maintenance strategy
Prevent failures and better prepare repairs.
The most suitable program depends on equipment criticality, service conditions, history and manufacturer recommendations.
Preventive maintenance
Regular inspections help monitor component condition and plan actions before a failure occurs.
- Inspection scheduling
- Belt wear monitoring
- Idler and bearing checks
- Fastener and guard inspections
- Fault and maintenance history
Corrective maintenance
When a defect is detected, the objective is to assess the risk, define a suitable repair and prepare a controlled return to service.
- Failure diagnosis
- Definition of repair scope
- Replacement of defective components
- Post-maintenance verification
- Recommendations to prevent recurrence
Health, safety and environment
Safety is an integral part of every intervention.
Before work begins, risks must be assessed and required permits obtained. Energy isolation, prevention of unexpected startup, mechanical guarding, PPE and work-area control must follow the site procedures.
Frequently asked questions
Prepare your maintenance project.
Available information about your installation helps us understand the requirement and prepare a suitable proposal.
What types of conveyors can you support?
The scope is defined after reviewing the installation. It may cover belt conveyors and their mechanical components, particularly in industrial, mining and material-handling environments.
Can you work on a failed conveyor?
An initial assessment helps determine required information, risks, resources and spare parts. Availability and response time must be confirmed for each case.
What information should be provided for a quotation?
Provide the site, conveyor type, belt length and width if known, conveyed material, observed issue, available photos and required timeframe.
Do you offer periodic maintenance contracts?
A periodic program can be considered based on the number of conveyors, their criticality, operating conditions, client requirements and agreed scope.
Do you provide a report after the work?
The report format can be agreed before the intervention and may include findings, work performed, affected components and recommendations.
