Why won't my Manitowoc National Crane NC1400H lift the load?
If your Manitowoc Construction Equipment jack won't lift the load, it could be due to a couple of reasons. First, check if there's enough oil in the system. If not, add oil to the reservoir tank through the oil filler hole. Another possible cause is that the release valve isn't fully closed. Make sure to turn the handle clockwise tightly to close it.
How to improve lifting on Manitowoc National Crane NC1400H Construction Equipment?
Poor lifting in your Manitowoc Construction Equipment can stem from a couple of issues. One possibility is dirty oil, which requires a hydraulic oil change. Another cause might be air trapped in the hydraulic system, so you should purge the air from the system.
What to do if Manitowoc National Crane NC1400H Construction Equipment will lift load only part way?
If your Manitowoc Construction Equipment jack will lift the load only part way, it's likely due to a low oil level. Add oil to the reservoir tank through the oil filler hole to resolve this.
What to do if Manitowoc National Crane NC1400H Construction Equipment jack will not lower?
If your Manitowoc Construction Equipment jack will not lower, the release valve is likely stuck due to dirt or foreign matter. To fix this, transfer the load, then replace the dirty oil and flush the oil reservoir with kerosene.
Why is there poor pumping action in my Manitowoc National Crane NC1400H Construction Equipment?
If your Manitowoc Construction Equipment exhibits poor pumping action, it's likely that the oil seal for the pump unit is worn out or defective. The suggested solution is to replace the jack.
What to do if Manitowoc National Crane NC1400H will lift load but will not hold?
If your Manitowoc Construction Equipment will lift a load but won't hold it, it could be due to a leaking valve (suction, delivery, or release valve) or worn-out/defective packings. The suggested solution is to replace the jack.
