Elastic Limit Locator JL0563(G)-02
Elastic limiting locator per TB/T 2075.3-2009 that adds resilience to the registration point for high-speed passage.
Specifications
| Model | JL0563(G)-02 |
|---|---|
| Standard | TB/T 2075.3-2009 (this model); series requirements apply to interface dimensions |
| Materials | Aluminum alloy lightweight structure |
| Installation | Mounted at the cantilever end, elastically limiting the contact wire position |
The elastic limit locator fixes the contact wire through an elastic limiting structure: unlike a rigid stop, it yields slightly under the pantograph's uplift and returns, adding resilience to the registration point so the wire's dynamic response at speed is softened rather than rebounded.
The design follows TB/T 2075.3-2009 and is one of the leading products of the Chuangwit positioning range. High-speed current collection behaviour is proven in line service.
Design Features
- Elastic limiting structure holds the wire position while adding point resilience
- High-speed current collection adaptability verified in line service
- Full type coverage: standard, elastic-limit and head-span versions
- Aluminum alloy lightweight structure, wide stagger adjustment range
The product is manufactured under CRCC railway product certification and an ISO 9001 quality management system, with incoming material inspection, in-process control on critical operations and batch-by-batch final inspection before delivery.
Frequently Asked Questions
What does elastic limiting mean?
The stop that limits wire uplift is elastic: under the pantograph it yields slightly and returns, so the registration point adds resilience instead of a hard rebound — smoother current collection at speed.
Which standard does this model follow?
TB/T 2075.3-2009, the edition current for this JL0563(G) design; interface dimensions follow the positioning family so it fits standard assemblies.
Where is it preferred over a rigid limit locator?
On high-speed sections where registration point resilience is part of the dynamic design — the elastic stop smooths wire response under the pantograph.
Is line-service experience available?
Yes — the elastic limiting design's high-speed current collection adaptability has been verified in line service and it is one of the leading products of this range.
Performance
Operating Conditions
Outdoor service at OCS registration points on mainline, high-speed and station structures, subject to suspension, wind, ice and dynamic pantograph loads as defined by the OCS design.
Mechanical Performance
Elastic element yields under pantograph uplift and returns, softening the dynamic response of the registration point at high speed.
Applications
High-Speed Lines
Elastic response tuned for pantograph passage.
Softer Registration Point
Yields and returns instead of rebounding.
