WaterWeights 6.5 Tonne Proof Load Test Bag – Rental
The 6.5 tonne WaterWeights Low Headroom bag has a wider, shorter body, so you get a useful test load where headroom is limited. It is ideal for proof load testing smaller overhead cranes, monorails, hoists, davits and lifting gear.
WaterWeights water-filled proof load test bags are a safer, more flexible alternative to solid test weights. The load is raised gradually and under control, so any problem shows up before the full test load is reached. An empty bag weighs only a small fraction of its test load, so it ships, handles and stores easily, and it is filled with water on site.
Specifications (Type BS 065L – Low Headroom):
- Safe working load (test capacity): 6.5 t
- Filled height (overall, to lifting point): approx. 13 ft (3.96 m)
- Filled maximum diameter: approx. 9 ft (2.74 m)
- Packed size (L x W x H): 1.00 x 1.20 x 0.80 m (approx. 3.3 x 3.9 x 2.6 ft)
- Packed weight: 150 kg (approx. 331 lb)
- Net (empty bag) weight: 115 kg (approx. 254 lb)
- Empty height: 4.00 m (approx. 13.1 ft)
- Filling connection: 2.5" Storz
- Use: Low Headroom bags are designed to hang one bag per lifting point. Hanging several bags from one point causes a significant loss of capacity, so use a spreader beam to combine bags.
