Description
The top left corner fitting is installed at the container's upper left corner for safe crane handling and lifting with twistlocks or hooks, and stable stacking. Each fitting undergoes multi-stage inspection, including ultrasonic or radiographic testing, dimensional checks and mandatory strength tests.
Suitable for all ISO container types, including 20-foot and 40-foot containers. Markings identify the manufacturer, heat number, production year, position code VL (top left) and the Russian Maritime Register approval stamp.
Advantages
- Designed for liftingOptimised for high lifting loads: at least 250 kN with a twistlock and 194 kN with a lifting hook
- Versatility and compatibilityCompatible with standard container handling equipment
- Exceptional strengthRated for extreme stacking loads up to 942 kN and impact loads of 150 kN
- DurabilityAt least 20 years of design service life using high-quality 20GL cast steel
Testing and quality control
Testing checks steel chemistry and mechanical properties, surface defects, and internal defects using radiographic or ultrasonic inspection. Samples from every batch undergo load tests simulating actual operating conditions.
- Stacking: up to 1,320 kN
- Twistlock lifting: 250 kN
- Impact: 150 kN
