1. The most basic components of the trolley line system. The most basic trolley line system should include the following component guides (including insulation jacket).
Connector (with joint jacket)
Conductor pendant (and pendant bracket)
Mounting clips End parts Power input parts Expansion parts Current collector mounting brackets 2. Slippery wire system Other possible parts Insulation parts Pick-up guides 3. Sliding-wire parts Number of steps for calculation Consider whether expansion is required Selection of component guides specification Considering the position and number of feed points Calculate the number of guides Calculate the number of joints and jackets Calculate the number of fixing clamps Calculate the number of lifting attachments Calculate the number of current collectors and brackets 4. Calculate the number of expansion components Consider Do you need expansion parts SL2- When the system length is less than 150 meters, no expansion parts are required.
The SL3-system is less than 200 meters in length without the need for expansion components.
Determining the Number of Expansion Parts When the system needs an expansion part, the number of expansion parts is determined according to the following formula.
n=(Tamax-Tamin)×(L-L0)×1000×ce/exp
The number of n-expansion parts Tamax - The maximum allowable temperature of the trolley wire (PVC jacket is 80°C, PPO jacket is 120°C)
Tamin - The lowest possible temperature in the field L - The actual length of operation of the system in meters
L0 - Maximum system length (unit: meters) without expansion components
Ce-expansion coefficient (galvanized steel-0.0000126/copper-0.0000162/aluminum-0.0000235)
Exp - working range of the expansion part (unit: mm)
SL2-50 mm SL3-200 mm Example: A 180-meter long system with a minimum ambient temperature of -10°C using standard aluminum conductors.
If using SL3 conductors do not need to configure expansion components.
If the SL2 conductor is used, an expansion member n=(80-(-10))×(180-150)×1000×0.0000235÷50≈1.3 is needed
If the value of n is a decimal, then no matter how big the decimal is, it needs to carry. In the above example, each phase (and each root) needs to expand two components. It should be noted that the same conditions use conductors of different materials and the number of expansion components is different.
For example: a 180-meter-long system with a minimum ambient temperature of -10°C using a standard type SL2 copper conductor. n = (80 - (-10)) x (180 - 150) x 1000 x 0.0000162 ÷ 50 ≈ 0.9 The same conditions for copper conductors and galvanized steel conductors require fewer expansion members than aluminum conductors.
5. Selection of guide bar specifications For systems with 380 V power supply, the running current of the vehicle is approximately twice the total power.
For a system that contains more than one vehicle, the total operating current of the system needs to consider the following conditions.
- One lane: The largest two motors in all the lanes - Two lanes: The largest three motors in all motors - Three lanes: The largest three motors in all motors - Four lanes: The largest of all motors After determining the operating current of the system, Taiwan Motor determines the coefficient (K) based on the following ambient temperature (Ta) and driving duty factor (Duty). The actual allowable current of the guide rod I = nominal current × K. It is necessary to select a guide rod whose I is greater than the actual operating current of the system.

Adjustable Customize Design Roll-up cover For Tool
Automatic retractable shutter shields, also known as rolling up cover, needs to fixed on the top of the machine and work with it. Shutter shields can divide into box type and bracket type. Box type shutter shields tank shell made of stainless steel or cold plate, plus the polished surface and anti-corrosion treatment. Protection belt is made of stainless steel or tri-protective cloth. In addition, it needs high precision and large elastic spring axis components.
