Data-use note: The table is a web-selection range assembled from Chinese supplier product pages and common China-market configurations. It is deliberately specific enough for product-page lead generation, but it is not a factory production guarantee. Final dimensions, pressure/load and materials are selected against the inquiry.

Construction & Material Platform

High-strength coated fabric body with reinforced lifting harness / webbing or, for supported distributed-load cells, a low-profile bladder body with fill/drain and vent ports. Water provides continuously adjustable test mass.

· Required proof load / ballast mass

· Suspended versus supported/distributed load

· Available headroom and footprint

· Fill rate, drain rate and water source

· Rigging points, load cells and test procedure

Selection & Configuration Guide

For a useful quotation, the buyer should provide the following information. This also helps distinguish a standard web-reference model from a custom engineered version:

· Required proof load / ballast mass

· Suspended versus supported/distributed load

· Available headroom and footprint

· Fill rate, drain rate and water source

· Rigging points, load cells and test procedure

Available Customization

· Capacity, overall dimensions and aspect ratio / geometry

· PVC, TPU, rubber or project-specific membrane platform as applicable

· Inlet, outlet, vent, bypass, inflation and drain connections

· Valve / flange / camlock materials and connection standards

· Colour, marking, OEM label and multilingual instructions

· Groundsheet, repair kit, hoses, control accessories, frames, straps or manifolds as applicable

· Packing method for courier, air freight, LCL or full-container shipment

Accessories & Optional Supply Scope

· Fill manifold

· Drain hose

· Load cell / flow meter interface

· Rigging accessories

· Protective tarpaulin / storage bag

Packaging, Transport & Storage

Products are normally supplied deflated or empty, dried and folded to minimise shipping volume. Smaller units can be carton packed; medium and large units are typically packed in reinforced woven/PVC bags, pallets or export cases according to weight, fittings and destination. Metal fittings are separately protected against impact. Store dry, ventilated and away from sharp objects, heat sources and aggressive chemicals.

Commercial Guidance

Item	Web / Inquiry Guidance
MOQ	Typical project supply can start from 1 set for large/custom items; smaller standardized items may use multi-piece MOQ.
Sample / Trial	Where size allows, a sample or small trial order can be arranged before project batch production.
Typical Production Lead Time	Common custom flexible-fabric products: approximately 10–30 working days depending on size, quantity, material and accessories.
Warranty Positioning	Website wording should state a project warranty agreed in the quotation; avoid promising a fixed period for every material/application without project confirmation.
Export Terms	EXW / FOB / CIF and project logistics can be quoted according to destination and shipment size.

FAQ

How is the test load adjusted?

By controlling the water volume. This allows gradual loading and unloading without transporting equivalent solid weights.

How large can a single suspended water bag be?

Chinese marine suppliers publish single-bag ranges up to about 110 tonnes.

Can several bags be combined?

Yes. Multi-bag rigging is commonly used for larger proof-load tests or distributed loading.

Are bridge load bags the same as suspended bags?

No. Bridge/floor bags are generally supported distributed-load cells, while crane proof-load bags are suspended from lifting points.
