Bottom Transfer Loading Arm| Emco Wheaton

Bottom transfer arms are especially designed to load products where vapor return is necessary while providing an extended reach that makes them ideal for applications where a vehicle cannot be accurately spotted.

Bottom Loading Station

This type of loading arm is specially designed to load products where vapour return is necessary.

Tank Truck Accessories

Emco Wheaton offers a range of accessories to help you further customize and enhance your chemical loading arm. From heated steam jackets and breakaway couplers, to pneumatic and hydraulic handling systems; we can provide you with the equipment you need to improve the safety, performance, and handling of your chemical loading arms.

Parallel Device for Bottom Loading Arms

The arm is fitted with six swivels for complete 3-axis movement of the tanker connection, allowing for tanker height changes during filling/discharge. The arm is additionally fitted with a parallel bar that holds the tanker connection arm ("B"-length) in a horizontal position irrespective of the primary arm ("A"-length) position. This makes tanker connection and disconnection much easier. The B-length also has a gas spring fitted allowing the operator to raise and lower the B-length with total ease.

Mechanical Quick Release System

Our mechanical Quick Release System provides automatic disconnection of a loading arm in the event of a tanker accidentally driving away. Simultaneously the product flow will be shut off both upstream and downstream of the disconnection point.

EM-En-Product-Photo-quick-release-system-pneumatic

Pneumatic Quick Release System

Our pneumatic Quick Release System provides automatic disconnection of a loading arm in the event of a tanker accidentally driving away whilst simultaneously shutting off the product flow both upstream and downstream of the disconnection point.

EM-En-Product-Photo-quick-release-system-hydraulic

Hydraulic Quick Release System

Our Hydraulic Quick Release System E0790 is used for the automatic separation of a connected loading arm from a tank vehicle in the event of an accidental drive-away whilst still connected. In this event, there is minimal loss of pressure in the rest of the connected supply.

Hose Release System for The Protection

Our Hose Release System is used for the protection of loading hoses during loading/unloading of barges, providing environmentally safe handling of loading hoses.

Telescopic Drop Tube

is used with a bottom contact switch, ensuring that the drop tube is permanently in touch with the bottom of the tanker being loaded. Our telescopic drop tubes can be either manually or pneumatically operated. Manually operated telescopic drop tubes are robust and have a short installation.

Heating Systems for Products

Designed to keep loaded fluids in a liquid state, used for products with low and middle temperature ranges or if there is no other heating media available.

Overfill Safety Device

Secondary safety system which prevents product overflow, for example in the case of an incorrect pre-selected loading amount.

Control Systems for Loading Arms

Systems for the comfortable and safe operation of loading arms.

SURELOK Couplings

Represent the most innovative method of producing fast and tight connection between two hoses or a vessel and a hose. These couplings comply with the safety requirements of the chemical and oil industries.

Vapor Cones and Plates

Adding a vapor cone or plate with a vapor recovery system on the arm, this improves the profitability of the terminal because vaporized product can be recovered and does not pollute the environment.
