1. What is range of freight elevator capacity?
From 1000 to 20000kg as common.
Following categories:
● Light load freight elevators: 1000-3000kg.Suitable for daily cargo transport in restaurants and shopping malls.
● Medium load freight elevators: 3000-5000kg.Meet the needs of small factories and warehousing centers.
● Heavy load freight elevators: 5000-10000kg.Used in manufacturing and logistics parks.
● Extra heavy-duty freight elevators: 10000-20000kg. Ideal for ports and heavy machinery plants.
2. What is relationship between freight elevator size and capacity?
It's size directly affects capacity and load:
● Cabin area: Approximately 500~800 kg per square meter.
● Cabin height: Influences how cargo can be stacked.
● Door opening size: Determines the ease of loading and unloading cargo.
● Calculation formula: Load capacity (kg) = Cabin area (㎡) × Load per unit area (kg/㎡).
Example: For a 2m × 2m cabin, at 600 kg/㎡, the load capacity is approximately 2400kg.
3. How to select freight elevator capacity based on cargo size?
Consider the following factors:
● Cargo dimensions: Measure the longest, widest, and tallest cargo.
● Loading/unloading method: Forklift access may require increased car width.Suggest adding at least 500mm wider than the forklift.
● Door opening size: Common freight elevator doors range from 1200 to 2500mm wide. Extra-wide doors require reinforced guide rails.
Example: When transporting machinery 2000mm tall, the car interior height should be at least 2300mm.
4. What are consequences of often overloading?
Overloading risks include:
● Mechanical failure: Accelerates wear on traction machines and increases the risk of wire rope breakage.
● Safety loss: May cause brake failure or buffer damage.
● Compliance risks: Failure to pass annual inspections (special equipment inspections require load error ≤5%).
● Solution: Install a dynamic weighing system that automatically halts operation and alerts when overloaded.
5. How do overload protection devices in freight elevators work?
FUJI elevators come standard with three-stage overload protection:
● Warning system: Emits audible and visual alerts when reaching 90% capacity.
● Operation restriction: Prevents door closure when exceeding 100% capacity.
● Emergency braking: Automatically halts operation during severe overloading.
These devices function through:
● Pressure sensors monitoring car load.
● Microcomputer control systems processing data.
● Mechanical linkage devices executing protection.
6. How is the safety margin for freight elevator capacity calculated?
This is based on 3 safety design principles:
● Mechanical safety factor: All load-bearing components (wire ropes, guide rails, etc.) are designed for 125% of nominal values.
● Dynamic load compensation: Additional loads occur during elevator acceleration/deceleration.
● Long-term wear allowance: Metal fatigue after 5 years reduces load capacity by approximately 15%.
Example: A freight elevator with a 5000kg nominal capacity is designed to handle 6250kg but must be strictly operated within 5 tons.
7. Is capacity of double-cabin freight elevator double that of single cabin?
A common misconception.
In actual operation, consider:
● Balance system limitations: Two cars share the same counterweight, with total load capacity typically 1.6 times that of a single car.
● Synchronization requirements: Weight difference between cars must be <15% to avoid system alarms.
● Efficiency loss: Actual transport volume is about 75~85% of theoretical capacity.
Example: Two cars with a nominal 5000kg capacity have an actual total operating load of about 8000kg and require an intelligent balance control system.
8. How can you determine if an existing building can accommodate a high-capacity freight elevator?
A 3-level assessment is needed:
● Foundation load-bearing capacity: Freight elevators over 5000kg require ≥150 kPa foundation strength.
● Hoistway structure: A 10000kg freight elevator needs at least 400mm thick reinforced concrete hoistway walls.
● Top floor height: An additional 0.5 meters of machine room height is required per ton of increased load capacity.
9. Can existing freight elevator capacity be increased through modifications?
Modification feasibility depends on:
● Whether the hoistway structure strength allows it.
● Whether the original drive system can be upgraded.
● The load margin of safety components (wire ropes, buffers).
General recommendations:
● Equipment under 10 years old may be considered for modification, costing about 60% of a new elevator.
● Older equipment is recommended for replacement, as modifications may not meet the latest safety standards.
10. Can the actual load of a freight elevator exceed its nominal value?
Absolutely prohibited!
However, understand these 3 key values:
● Rated load: The safety value marked on the nameplate (e.g., 5000kg).
● Test load: 125% during factory testing (6250kg).
● Ultimate load: Safety gear activation threshold at about 140% (7000kg).
Temporary overloading by 10% may not cause immediate failure but can lead to:
● Wire rope elongation and deformation, guide rail uneven wear, and electrical system overheating.
