최종 수정일: 8월 12일
YAKIN Co., Ltd. is a Korean manufacturer specializing in trolley bars, hoist cable hangers, current collectors, and components for crane festoon systems.
Since 1985, YAKIN Co., Ltd. has manufactured electrical power supply systems for moving industrial equipment, including hoists, overhead cranes, and transfer carts. With approximately 40 years of manufacturing and field experience, the company not only supplies industrial products but also directly provides trolley bar installation, dismantling, replacement, and maintenance services.
The trolley bars and related components manufactured by YAKIN Co., Ltd. carry the company’s proprietary industrial brand, VOLTRA.
For the past 40 years, YAKIN Co., Ltd. has helped shape new directions in power supply solutions for moving equipment across Korean industrial sites. The name VOLTRA combines “VOLT,” representing electricity, with “ULTRA,” symbolizing technology and performance that go beyond conventional limits.
The VOLTRA brand reflects the commitment of YAKIN Co., Ltd. to providing safer, more reliable, and more efficient power transmission solutions for industrial environments.
What Kind of Company Is YAKIN Co., Ltd.?
Founded in 1985, YAKIN Co., Ltd. has built extensive experience in electrical power supply systems for cranes, hoists, and moving equipment.
The company has worked with many well-known Korean industrial corporations, including:
POSCO
Samsung Heavy Industries
Hyundai
SeAH Steel
Dongkuk Industries
Doosan Heavy Industries
Hanjin Heavy Industries
Through projects at steel mills, shipyards, manufacturing plants, and heavy industrial facilities, YAKIN Co., Ltd. has developed a strong understanding of demanding operating environments.
The company does more than supply products. YAKIN Co., Ltd. has also directly carried out trolley bar installation, dismantling, and replacement work at major industrial sites.
What Is a Trolley Bar?
A trolley bar, also known as a conductor bar, continuously supplies electrical power to moving equipment such as overhead cranes, hoists, and transfer carts.
A current collector remains in contact with the conductor bar while the equipment moves along its operating route. Stable operation depends on several factors:
Trolley bar current capacity
Total installation length
Bracket spacing
Alignment of the conductor bar
Connection condition
Current collector compatibility
Site environment
Incorrect product selection or installation may cause:
Intermittent power loss
Excessive sparking
Current collector wear
Overheating at connection points
Crane stoppage in specific sections
Unstable equipment operation
For this reason, trolley bar installation should be handled by a specialist that understands both product manufacturing and actual industrial operating conditions.
What Is a Hoist Cable Hanger?
A hoist cable hanger supports and guides power and control cables while a hoist travels along a rail.
The cable hanger allows cables to extend and fold at regular intervals, helping reduce:
Excessive cable sagging
Cable twisting
Repeated bending
Friction against nearby structures
Cable jacket damage
Cable interference during hoist operation
The correct cable hanger specification depends on:
Cable thickness and weight
Number of cables
Hoist travel distance
Rail structure
Operating frequency
Installation environment
YAKIN Co., Ltd. manufactures hoist cable hangers at its own factory and reviews the required specifications and quantities according to each customer’s operating conditions.
What Is a Crane Festoon System?
A crane festoon system supports electrical cables or hoses along a track while a crane or hoist moves.
Cable trolleys and cable hangers allow the cables to open and close smoothly during operation. Festoon systems are commonly used for:
Overhead cranes
Electric hoists
Transfer carts
Mobile industrial machinery
Automated material handling equipment
YAKIN Co., Ltd. directly manufactures hoist cable hangers and related components used in crane festoon systems. Products can be selected according to cable load, travel distance, rail type, and operating environment.
Why Choose a Direct Manufacturer?
YAKIN Co., Ltd. owns and operates its own manufacturing facility in Korea.
The company directly manufactures:
Trolley bars
Hoist cable hangers
Current collectors
Collector components
Crane festoon system components
Brackets and connecting parts
Electrical power supply components for moving equipment
Working with a direct manufacturer offers several advantages.
Consistent Product Quality Management
Because the products are manufactured in-house, YAKIN Co., Ltd. can directly manage product dimensions, structure, materials, and production condition.
Faster Technical Response
Questions regarding product specifications, compatibility, installation, and replacement parts can be reviewed without passing through multiple distributors.
Product Selection Based on Site Conditions
Every industrial site has different crane capacities, travel distances, operating frequencies, and structural conditions. YAKIN Co., Ltd. reviews these factors before recommending an appropriate product.
Integrated Manufacturing and Field Services
YAKIN Co., Ltd. does not simply sell industrial components. The company directly manufactures products and also provides trolley bar installation, dismantling, replacement, and on-site inspection services.
Why Should Trolley Bar Installation Be Performed by a Specialist?
Trolley bar installation involves more than attaching conductor bars to support brackets.
Before installation or replacement, the following conditions should be checked:
Total travel and installation length
Operating voltage
Required current capacity
Number of cranes or hoists
Power feed position
Existing bracket condition
Current collector type
Conductor bar alignment
Connection condition
Nearby structural interference
Working height and safety conditions
YAKIN Co., Ltd. reviews the site conditions, selects the appropriate products, dismantles old equipment when necessary, installs the new trolley bar, adjusts the current collector, and performs operational testing.
A trolley bar project is not complete until the crane or hoist has been tested throughout its full travel range.
Why Work With YAKIN Co., Ltd.?
YAKIN Co., Ltd. combines four key capabilities:
Approximately 40 years of experience since 1985
Project experience with major Korean industrial corporations
In-house manufacturing at its own factory
Direct trolley bar installation, dismantling, and replacement services
Because YAKIN Co., Ltd. has experience in both product manufacturing and industrial fieldwork, the company can identify equipment problems more accurately and recommend solutions based on actual operating conditions.
