Question & Answer, Automatic handcuffs, Hulkkuffs Canada
Q1: Do we need to change the handcuffing standard operating procedures (SOPs) in training or operating ?
A1: No. Hulkkuffs are designed to fit all Standard Operating Procedure (SOP) for handcuffing. Hulkkuffs reduce stress in handcuffing, speed up the overall procedure, lower the risk of escalation, make more room for officers to focus on safety.
Q2: Would the new handcuffs get malfunctioned when the tension mechanism fails or gets stuck by something.
A2: No. Hulkkuffs are to lock/engage 3-tooth ahead of the tension control, or, in other words, the tension mechanism is activated only after the forward lock systems are engaged.
Q3: Would the handcuffs get over-tightened when the tension control fails ?
A3: No. If the mechanism fails, it may activate earlier (make it more or less like conventional handcuff), and it only activates after the handcuff is firmly cuffed on a wrist . The over-tighten mechanism is more reliable than the double-lock of the conventional handcuffs in any circumstance.
Q4: Would the tension control blocks the handcuff from being opened with a key, for example, the handcuff would not be removed freely when the tension control fails ?
A4: No, the stop pawl of the mechanism is uni-directional, and is spring loaded. It has no resistance in loosing / opening direction in any situation. (It is resistant only in tightening direction after activated).
Q5: Do we need to lub the Hulkkuffs regularly ?
A5: Lubrications have been made in factory, no lubrication required in daily operations. Customer lubrication is not recommended because most lubs catch dirt and debris and may block the parts from moving properly or freely.
Q6: Why do the Aluminum alloy handcuffs cost so much than steel handcuffs?
A6: Aluminum alloys, 7075 and 6061, are much soft than steels. Aluminum alloys parts must be tempered (heat treated according to specific temperature curves) to gain their strengths. The heat-treated processes are time consuming and experience-intensive.
Q7: Are all aluminum alloy handcuffs are better than steel or stainless steel handcuffs ?
A7: NO. It depends. Aluminum alloys return to their “soft origin” in strength after manufacturing ( forging , stamping/punching , and milling). Un-tempered aluminum alloys cannot be used in handcuff parts. Aluminum handcuffs are not always as good as steel ones unless their are properly tempered.
Aluminum alloys 7075 and 6061 become 7075-T6 and 6061-T6 after tempered, their strengths are much higher than steel and stainless steel based on their weight ratios.
Q8: What precautions should be taken when using Hulkkuffs ?
A8: Always keep keys in reach, you cannot remove the handcuffs by using standard handcuff keys.
Q9: What do you mean that the Hulkkuffs are 70-80% faster than conventional handcuffs ?
A9: Actually it is even faster in non-compliant situations. “This is a matter of lifesaving, not time-saving.“
