The Hook-Clamp is now ready to be loaded. Once the safety / hitch pin is removed, the Hook-Clamp is armed and ready to be released. Either to “set down” a load or to drop a load in a controlled manor (as a drop test / dropping clamp)

Air Cylinders provide another method of release and are fitted for activation using shop air at 60 to 100 PSI.The Hook-Clamp consists of several moving parts that allow the 'jaw' to open and release a load, generally you would use a release line to attach to the lever, pull this line and the load will release. Alternative Methods of Release

Welding, Heat Treatment, and Lubrication - All welding is with 17-4 SS wire only. All welded parts and pins are thoroughly cleaned and heat treated to H-1025 which increases the rating of the welding by 20-30% and the parts by 15%. Heat treating also results in improved mechanical, fatigue and corrosion properties across the board. Final assembly of the product includes the light application of a lubricant to each pin such as AQUA Lube, to protect the pin surfaces from pitting during extended marine use and aid in smooth mechanical function of the device. For higher capacity units, an NLGI #2.5 grease with moly added and a temperature range from 0 to 425F is applied. Sub-Sea use, made completely from aerospace-gradestainless steel the HookClamp has the ultimate in corrosion resistance. After use in or near sea water, a fresh water rinse of the Remote load release device is advised before it is stored. Toggle latches can come with or without catch plates, strikes or split pins as optional features for helping to secure the closed latch. They are available in a diverse selection of models and configurations, including:To prevent the need to work at height, enabling the load to be disconnected from distance with-out the need to climb onto the load. A multitude of general Industrial applications; indeed for any application where the rigging gear needs to be disconnected though is is an awkward, difficult to get to position. Automatic remote release of the rigging gear prevents unavoidable accidents. Effort required to release the load can be adjusted to suit your application (effort can be reduced or increased)

Inertial Load: A load resulting from accelerated releasing caused by tension on the object that is greater than gravity. It is important to test the effort frequently after some material has been removed so as to prevent the removal of too much material. The "S-Series" Hook-Clamp is affixed to a steel plate to allow more accuracy when attempting to release a load, applications such as towing and off-loading in the ocean are perfect for this Hook-Clamp Hydraulic pressure to drive a hydraulic cylinder to actuate the release lever of the Remote load release device is being used with the device ram models. These units can be activated by hydraulic hand pump, air-hydraulic foot pump, or electric pump. Ideal for use in the water utilities industry to automatically place pumps into sumps or wet wells.Once the safety hitch pin has been removed the clamp is“loaded” or “Live” and pulling the cord attached to the release lever WILL DROP / RELEASE the load. Pulling firmly on a release line connected to the end of the release lever also means that the operator can safety release the load away from the “danger area”. The release line can be activated “Directly” in any direction within the 90 degrees perpendicular and parallel to the line of load. The “Standard” release lever can also be operated from above the load as shown in the diagram below with the use of a suitable pulley; effectively giving 180 degree operation. Conversion for subsea ROV operation (Work class Remote operated vehicle also referred to as WROV usually by manipulator arm though also can be converted to hotstab. The manual release lever can be supplied pointing down (towards the opening jaw) for automatic release applications below ground; pulling up releases the load (known as a reverse lever). Alternatively the release lever / arm can be supplied pointing up (towards the rigging gear / anchorage eye) and this is used for automatic release applications where the operator is below the load. Both lever types can release the load when the operator is adjacent to the HookClamp. Do not side load the Remote load release device as it may cause loss of retainer rings and other parts or permanently damage the device.
