6 Rail Types Used in Rail Transfer Carts for Smooth and Flexible Transport
Straight Rail
- Suitable for all rail transfer carts.
- Foundation form for straight-line round-trip transportation scenarios, simple to lay and easy to construct.
L-Rail
- Suitable for KPGX (battery type) rail transfer carts.
- Suitable for scenarios requiring 90-degree steering, allowing for corner placement between workshops.
S-Rail
- Suitable for KPX, KPD rail transfer carts.
- Suitable for complex routes and multi-corner layouts; motor and frame need to have strong steering adaptability.
Railroad Switching
- Optional function expansion.
- It realizes the convergence and diversion of multiple track lines and supports multi-car switching and automatic dispatching systems.
Insulated Rail
- Applicable to KPD (low-voltage power supply type) rail transfer carts.
- The rail needs to be insulated to ensure the safety of 36V AC low-voltage power supply. When the operating distance exceeds 70 to 80 meters, a step-down/step-up transformer needs to be added to compensate for the voltage drop.
Sliding Line Rail
- Applicable to KPH (sliding contact type) rail transfer carts.
- The sliding contact line can be installed in the trench flip plate device on the outside of the track, without being restricted by the running distance.
4 Flexible Power Choices for Rail Transfer Carts to Fit Your Site
The rail transfer carts are specially designed to provide the most efficient and heavy-load transportation services for industrial plants. Rail transfer carts usually operate on tracks in a factory or warehouse area. The load capacity of the rail transfer carts can reach up to 1,000 tons, and different models can be provided according to the factory’s requirements. There are four power supply methods for the rail transfer carts:
Battery Powered Rail Transfer Carts
Advantage
- Does not rely on external power supply
- Supports turning tracks (straight, L-shaped, S-shaped, arc-shaped)
- Easy to install and with low requirements for tracks
Disadvantage
- Battery life is limited
- Regular charging and maintenance are required
Aplikasyon
Cross-workshop transportation, complex routes, and no power supply areas on site.
Busbar Powered Rail Transfer Carts
Advantage
- Automatic continuous power supply
