Safety Breakaways

Protect Against Drive-Offs

Are you prepared if a driver accidentally pulls away from your terminal while still connected to your loading arm, hose or tank?

SafeRack’s wide selection of safety release systems and breakaway couplings protect your workers from accidental pull-away accidents during loading and unloading. Designed to reduce costs and downtime, our systems seal the valve on both sides, keeping spills — and any equipment damage — from occurring.

safety breakaway systems

Standard Breakaway System

The TODO Standard Break-Away Coupling has been designed to eliminate spillage and damage associated with drive and/or pull-away incidents when loading and unloading hazardous liquids. The coupler automatically senses an excessive load, closes the valves and then allows disconnection.

SPECS
  • High flow rate / low pressure drop
  • Encapsulated shear bolts
  • Operates independently of shut off safety systems and does not require an external power source
  • Will release at any angle of pull
  • Marine and Collar Release versions available
  • Easy to re-set on site

SPECS
  • High flow rate / low pressure drop
  • Encapsulated shear bolts
  • Operates independently of shut off safety systems and does not require an external power source
  • Will release at any angle of pull
  • Marine and Collar Release versions available
  • Easy to re-set on site

collarreleaseproduct

Collar Release Break-Away

The TODO Collar Release Break-Away Coupling is new to the TODO range and offers an alternative to the standard range serving a very different purpose. Like the standard product, it has been designed to eliminate spillage and damage associated with drive and/or pull-away incidents when loading and unloading hazardous liquids, but the added benefits of safeguarding loading arms.

When used with loading arms, the break-away is engineered to disconnect if the arm travels past the customer designated breakage position. The actual collar is linked via break cable to the loading arm so that once the break position is reached, the collar splits, closing the valves off. In addition to reducing any potential environmental impact from a break, the loading arm is safeguarded and potential costly downtime is avoided.

The Collar Release version of the Break-Away Coupling is appropriate for use with a range of products including oil, fuels, chemicals and foods. It is typically found used in conjunction with distribution loading arms to assist with the reduction of damage to the arm should disconnect occur.

SPECS
  • High flow rate / low pressure drop
  • Operates independently of shut off safety systems and does not require an external power source
  • Will release at any angle of pull
  • Marine Break-Away and Standard Break-Away versions available
  • Easy to re-set on site

hose quick release

Hose Release System

Our Hose Release System is used for the protection of loading hoses during loading/unloading of barges, providing environmentally safe handling of loading hoses. If the connected loading hose is stretched over the allowable working envelope, the cable will be activated. The shear pin will break and the clamp collar of the release unit will unlock. The two halves of the coupler will divide preventing damage to the installation or the vehicle. The spring loaded poppets cut the product flow of the hose and the vehicle completely so that leakage is avoided.

SPECS
  • Connection flange for hose or quick release system E0790
  • Bearing with lateral plumber block for connection to site steel work
  • Weather proof cover
  • Swivel joint D2000
  • Swivel joint anchor plate for connection to site steel work
  • Connection flange for customer's pipe work

quick release system

Quick Release Hydraulic 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. Our loading arms and the vapor return arms are provided with a quick release system with reduced diameter. The diameter of the system is designed to be 3" for the loading arm and 2" for the vapor return arm. Our Quick Release System consists of two standard ball valves and the release coupling, which is clamped together by a collar assembly. With the use of a lever, first the ball valves are closed and then the collar release is activated. Due to the high operating force a hydraulic cylinder is required for the activation. The system is controlled hydraulically according to the circuit diagram shown, i.e. with a hydraulic limit switch in the slew range between the F- and A-length of the arm. The release will be initiated either by the product arm or the vapor arm, depending on which of them is outside of its safe working envelope first. The hydraulic accumulator and the control system are located in a control cabinet with a conductive surface.

SPECS
  • Power operated by compressed air
  • The pressure converter is a pneumatic cylinder
  • Connection flange sensor prevents accidental release whilst maneuvering the loading arm
  • The system is explosion proof EEx i; an alarm at the client's installation can be provided

e0790 machanic

Quick Release Mechanical 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. The system can be used on a variety of loading applications. The quick release unit is fitted as an integral part of the outboard end (B-dimension) of the loading arm. Both valves are clamped together by a collar assembly. The actuation cam fitted to the double swing joint activates the collar release via the bowden cable. Also fitted to the double swing joint is a shear pin which prevents accidental release whilst maneuvering the loading arm.

SPECS
  • Release unit with integral shut off valves
  • Mechanical release mechanism
  • Shear pin
  • Material of product carrying parts: Stainless steel ASTM A 316
  • Seal: EPDM; Viton; PTFE
  • Working pressure: PN 40

e0790 pneumatic

Quick Release System Pneumatic

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. The system is used at single loading arm stations and bottom loading stations. The quick release unit is fitted as an integral part of the outboard end (B-dimension) of the loading arm. Both valves are clamped together by a collar assembly and the clamp is released by a pneumatic cylinder. A limit switch fitted to the double swing joint, and controlling the rotation angle, activates the cylinder. The connecting flange sensor and a shear pin, also fitted to the double swing joint, prevent accidental release whilst maneuvering the loading arm.

SPECS
  • Connecting flange sensor
  • Pneumatic control system
  • Shear pin
  • Material of product carrying parts: Stanless steel ASTM A 316
  • Seal: EPDM; Viton; PTFE
  • Working pressure: PN 40
