Tools for engineers

Engineering tools & calculators

Quick screening tools for selecting and sizing conveyors. Results are preliminary estimates, not approved engineering designs; ENTRA confirms every design.

SIMPLE SELECTION & ENGINEERING TOOLS

Choose the right conveyor — or explore the engineering tools

New to conveyor systems? Start with the simple selector. Already know your requirements? Use the engineering calculators and share your results with our team. You can begin with a few basic details — no technical background needed.

Preliminary engineering estimates only. Results are for early-stage screening and enquiry preparation, not final equipment selection, motor approval, safety validation or certified design. ENTRA must verify product data, duty cycle, friction, chain/belt manufacturer limits, structure, controls and site conditions before quotation or manufacture.

STEP-BY-STEP BEGINNER DECISION GUIDE

Find Your Best Conveyor System in 4 Clicks

NO CAD REQUIRED

1. What primary product are you transporting?

2. What is your factory floor environment?

3. Conveyor Line Path Geometry

4. Single Item Weight Range

BEGINNER TIP

Acetal multiflexing chains (modular-chain layout) allow a single drive motor to carry bottles or cartons around 90° and 180° corners without needing extra transfer motors at every turn!

ENTRA RECOMMENDATION

SUGGESTED STARTING POINT

Checking your conveyor requirements…

Ideal for beginners and fast-moving packaging lines: a single SEW gearmotor pulls the low-friction acetal chain through straight runs and tight S-bends with zero belt tracking adjustments required.

GEOMETRY & PHOTOELECTRIC SENSOR WINDOW CALCULATOR

Belt Frame Width, Product Pitch & Optical Sensor Gap Validator

PLC SENSOR CHECK

1. Product Length along Belt (Lp) 240 mm

2. Product Width across Belt (Wp) 180 mm

3. Target Throughput (Units / Min) 45 BPM

4. Selected Belt Speed (v) 18 m/min

WHY THIS MATTERS FOR BEGINNERS: If your belt runs too slowly for your target Boxes Per Minute (BPM), products will touch each other (Window Gap < 35mm), blinding your PLC photoelectric counting sensors and causing jams at diverter arms!

WINDOW GAP (G) 160 mm Center Pitch: 400 mm

✓ 160 mm gap between units provides clean optical sensor triggering and barcode scanning margin.
