1. What is Pusher Cycle Time?

Pusher Cycle Time consists of maneuver time and load time in earthmoving operations. It represents the total time required for a pusher to complete one full cycle of assisting scrapers.

2. How Does the Calculator Work?

The calculator uses the Pusher Cycle Time formula:

Where:

• \( T_p \) — Pusher Cycle Time (Second)
• \( T_s \) — Scraper Cycle Time (Second)
• \( N_p \) — Number Of Scraper A Pusher (Number)

Explanation: The equation calculates the pusher cycle time by dividing the total scraper cycle time by the number of scrapers a pusher can load.

3. Importance of Pusher Cycle Time Calculation

Details: Accurate pusher cycle time calculation is crucial for optimizing earthmoving operations, equipment scheduling, and project planning in construction and mining industries.

4. Using the Calculator

Tips: Enter scraper cycle time in seconds and number of scrapers a pusher can load. All values must be valid (scraper cycle time > 0, number of scrapers ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What factors affect pusher cycle time?
A: Maneuver time, load time, equipment efficiency, operator skill, and site conditions all influence pusher cycle time.

Q2: How is scraper cycle time determined?
A: Scraper cycle time is estimated by adding fixed times for loading, dumping, and turnaround maneuvers.

Q3: Why is this calculation important for project planning?
A: It helps optimize equipment utilization, determine required number of pushers, and accurately estimate project timelines.

Q4: Can this formula be used for different types of earthmoving equipment?
A: While the principle applies to similar equipment configurations, specific coefficients may vary based on equipment type and site conditions.

Q5: How does the number of scrapers affect pusher efficiency?
A: Increasing the number of scrapers a pusher can service generally improves overall equipment efficiency and reduces idle time.
