Mavi Deniz, water-filled load Test Bag designed for crane, lifting equipment, lifeboat, gangways load test operations. The capacity of each water bag is up to 100 tonnes.

Crane Water-filled Testing Weight Bags

Streamline your crane testing operations with Mavi Deniz load test bags and load measuring products. Crane Test Water Bags are made from 100% “High Tenacity” PVC coated polyester fabric material, which comes ready with: safety shackles, master link, fluid transfer fittings, and valves required for operation.

The Mavi Deniz Crane Load Test Bags’ continued development has substantially increased the practicability, economy, and safety of providing load testing on cranes in power plants, general industry, construction, and marine operations. These bags can also use as emergency fluid storage containers.

During transportation and staging, the bags with load cells weigh just a fraction of their rated capacity keeping freight costs, storage space, floor loading, and especially workforce to a minimum.

Crane Test Water Bags features are:

  • Foldable for easy storage and transportation.
  • Used worldwide for ship-deck cranes, offshore rigs, and general-purpose cranes.
  • Water Bag 3D Model FEA (Finite Element Analysis) Force & Stress
  • Test multiple crane sizes with one fluid weight.

Testing Applications include, but is not limited to:

  • Cranes
  • Winches
  • Davits
  • Pad Eyes
  • Hoists
  • Beams
  • Gantries
  • Elevators
  • Monorails
  • Floors
  • Ramps
  • Platforms
  • Gangways
  • Lifts
  • Bridges

Capacities range from 1 to 100 Tonnes ( 1,000 to 100,000 Kg).

The continued development of water-filled proof load bags has substantially increased the practicability, economy, and safety of providing proof load testing on cranes in power plants, general industry, construction, and marine operations.

The bags with load cells weigh approximately 2% of their rated capacity during transportation and staging, keeping freight costs, storage space, floor loading, and especially workforce to a minimum.

The load is always measured accurately with a certified loadcell or flowmeter, so exact weight variations required during the test are always achieved by filling or dumping the bags.

Testing Applications include:

  • Crane-Davits
  • Derricks
  • Winches
  • Davits
  • Pad Eyes
  • Hoists
  • Beams
  • Gantries
  • Elevators
  • Monorails

Davit, Lifeboat, Gangway Water-filled testing weight bags

Lifeboat and Davit Test Water Bags used for evenly distributed load tests. These load test bags come with fill/offload fittings and an automatic relief valve activated once the lifeboat bags achieve the desired weight.

Mavi Deniz Lifeboat Testing Systems designs to provide a safe and straightforward test load to life-saving appliances. Lifeboat test bags allow for gradual application and uniform distribution of the load. Controlled loading, unloading, and minimal handling of the test load to achieve a wide range of capacities result in minimum equipment downtime during load tests.

Lifeboat Testing Systems are an extremely safe and straightforward method of proof load testing. The bags are light and easily positioned and fulfill the requirement for an evenly distributed load test. A control manifold and pumping system are used to remotely fill and drain the water bags, negating the need for personnel to be in the craft while undergoing a proof load test. Loading is measured and verified using a calibrated flowmeter.

Gangway Load Testing Bags are also available and offered in all custom sizes.

These bags’ accessories include pumps & manifold systems, hoses, carry/storage satchel, and Marine-grade shipping/storage plywood box.

Some of the Lifeboat Key features are:

  • Foldable for easy storage and transportation.
  • Made of high-strength coated fabrics.
  • Complete with all accessories and fill/offloading systems.
  • Flat Bottom Lifeboat Bags are also available.
  • Complete Lifeboat Testing System Kit available.

Testing applications include, but is not limited to:

  • Lifeboat load testing
  • Life Raft load testing
  • Gangway load testing
  • Free Fall Lifeboat testing
  • Davit Launch Life Raft testing
  • Platform & Dock testing
