Hydraulic Cylinder



The application of hydraulic cylinders is limited to amphibious excavator with extendable
function only.



When extended, the hydraulic cylinder shaft is exposed to air, water and other solid objects
that can cause corrosion or serious scratch. When the shaft surface is no longer smooth, the
seals could not hold the pressure and then cause hydraulic oil leakage.



Since the shaft is not protected during extension, the risk of corrosion and damage can be
reduced by retracting the shaft during parking. When the shaft is sealed inside the barrel,
the hydraulic oil will protects the shaft from outside contaminants and hence longer the
shaft life and maintain the hydraulic cylinder performance.



Extra  care  is  required  if  the  supplementary  pontoons  are  attached  to  the  amphibious
undercarriage.  This  is  because  supplementary  pontoons  only  could  be  attached  to  the
amphibious undercarriage  during  extendable  mode  and  the  undercarriage  is  unable to  be
retracted  until  the  supplementary  pontoons  are  removed.  During  this  time,  the  hydraulic
cylinder shaft must be cleaned each time at the end of daily job. Get the machine out from
water and remove all the objects  such as earth, mud, or weed that stick on the shaft and
apply grease or oil at the shaft surface for extra protection.
