The mounting platform must be designed by a registered Skilled engineer, and obviously the "soaked" weight of the power unit and assist should be acknowledged. It is usually sensible to consult the crane manufacturer usually they are interested in delivering guidance and pertinent information and facts.
Warning pay near attention to how the shackle is orientated. It is achievable that the hoist line employed for the pile hammer may rub, and afterwards probably use the cotter pin, creating potential damage to the hoist line or perhaps the cotter pin (crucial) being dislodged after a while.
