Model 2429 Lock Down Device

The Lock Down Device secures top loading arms in the operating position, preventing upward movement during filling operations. Once the drop tube is positioned in the manhole, the operator engages the lock before starting the fill. At the end of the operation, raising the arm releases the locking mechanism.

These devices are particularly effective in installations without a pneumatic system, maintaining consistent pressure on the manhole. This ensures a continuous seal and supports efficient vapour recovery.

Alternative models are also available to suit different operational needs. The Model 4942 Lock Down Device is manually operated via a control lever, locking the arm in place by screwing it in. Meanwhile, the Model 4659 allows the operator to adjust the arm during loading, ensuring proper pressure of the cone on the tank’s manhole.
