sounds like youre spool lock is acting up for the bucket
thru the dipstick and vent hole by your bucket levers
EXCAVATOR are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with Hydraulic cylinders and Hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.
Sounds like you got hydrolocked. You'll have to relieve pressure on the hydraulic cylinders, by loosening the connectors for the hydraulic lines.
Aerial bucket trucks use a hydraulic lift to put workers at a desired height. One worker stays in the bucket on the exterior of the vehicle while another rides inside to operate the truck.
I'm assuming you are talking about the flexible hose that controls the bucket swivel. Mine exploded on me the other day. I ended up grabbing a bucket for all of the hydraulic oil that may have been left in the line and simply loosened off the nuts. For the one end of the hose that connects to the solenoid, you have to loosen the largest nut counter clockwise (left). And for the other end of the hose that connects to the solid steel line, you must turn the second largest nut counter clockwise (left). Try looking for the threads on the valves to determine which nut to loosen.
Purge slowly into a pail or bucket in the telemotor hydraulic system purging valve until such a time pure hydraulic oil are coming out from the purging valve.
Assuming you have checked the hydraulic fluid and it's OK, you could look into replacing the seals on the compression cylinder, but with jacks as inexpensive as they are these days, it would be easier and maybe even cheaper to replace the jack. I routinely see two-ton jacks on sale at automotive stores for $20-30. just check the rubber seling at bucket's bottom of the ram and plunger they wear of.f
A bit bucket is a supposed place in where bits go when they fall off the end of a register during a shift operation - also known as the Great Recycle Bin in the sky.
Your description is vague to say the least - but I think you mean a 'hydraulic ram' that raises the bed of a dump truck to empty it.
The steps produce considerable energy dissipation along the chute and Second, at the base of a spillway, a flip bucket can create a hydraulic.
If your bucket is not working, check the quick-disconnects on the hydraulic hoses for the loader. Brush or vibration will sometimes slightly retract the spring-loaded collar on the outside and even a slight disconnect will suck in enough air that the loader will not work or will work very slowly.
