FEM Combined Cycle Time Calculator
Estimate the mean combined cycle time tm2 for a mini-load or AS/RS stacker crane based on the FEM 9.851 standard case with combined infeed and outfeed at the lower corner point. A double cycle represents a combined operating cycle in which one storage and one retrieval are executed within a single trip.
FEM 9.851 standard case, combined cycle, lower corner point.
P1 = (1/5 · L, 2/3 · H)
P2 = (2/3 · L, 1/5 · H)
tm2 = t(E→P1) + t(P1→P2) + t(P2→A) + t02
The additional time t02 consists of positioning, place check, switching and control, and load handling.
Each travel time is calculated as max(Δx / vx, Δy / vy).
Conveyor Throughput Calculator
Estimate conveyor throughput based on belt speed, product length, and the minimum gap between products.
Throughput = belt speed / (product length + gap)
Product length and gap are converted from millimetres to metres automatically.
The result assumes steady single-lane flow.
Bottleneck Finder
Identify the bottleneck segment, effective line throughput, utilisation by segment, line balancing index, and a practical upgrade target.
Effective line throughput = minimum segment capacity
Segment utilisation = bottleneck throughput / segment capacity
Line balancing index = sum(capacities) / (max capacity × number of segments)
Upgrade suggestion = raise the bottleneck at least to the next limiting segment or by 20%, whichever is higher.
Pallet Conveyor Capacity Calculator
Estimate how many pallets can accumulate on a conveyor based on usable conveyor length, pallet length, and safety gap.
Capacity = floor((conveyor length + gap) / (pallet length + gap))
Pitch = pallet length + gap
This is a simple static accumulation model without dynamic braking zones.
Storage Capacity Calculator
Estimate how many totes or bins fit into a rack block based on usable rack dimensions and tote outer dimensions.
Capacity = floor(rack width / tote width) × floor(rack depth / tote depth) × floor(rack height / tote height)
This is a simple block-stacking model without clearances, beams, or structural obstructions.
Picking Performance Calculator
Estimate theoretical picks per hour for one operator based on reach, scan, and packing time per item.
Picks per hour = 3600 / (reach + scan + pack)
This is a simplified one-piece-flow estimate for one operator without waiting, walking, congestion, or fatigue factors.
Container Tilt Stability Calculator
Calculate the maximum tilt angle before a container tips or slides, including centre-of-gravity offset and optional friction.
Tipping: tan(θ) = x / Hcg, where x = (b / 2) − offset
Sliding: tan(θ) = μ
If friction is provided, the lower of tipping angle and sliding angle governs.
Plastic tote on steel rollers: μ = 0.15–0.25
Plastic tote on aluminum: μ = 0.20–0.30
Plastic tote on PVC conveyor belt: μ = 0.30–0.50
Plastic tote on rubber conveyor belt: μ = 0.40–0.60
Cardboard carton on steel rollers: μ = 0.30–0.40
Cardboard carton on PVC belt: μ = 0.40–0.55
Cardboard carton on rubber belt: μ = 0.55–0.65
Wooden pallet (EPAL) on steel rollers: μ = 0.25–0.35
Wooden pallet (EPAL) on galvanized steel: μ = 0.20–0.30
Wooden pallet (EPAL) on rubber surface: μ = 0.50–0.70
Wooden pallet (EPAL) on concrete: μ = 0.40–0.60
Incline Geometry Calculator
Enter any two values and calculate the third. The tool also returns the resulting incline length.
tan(α) = H / S
Incline length L = √(H² + S²)
Enter exactly two values. The third is calculated automatically.
