To prevent the standard Doosan 22-tonne crawler excavator from sinking into the water, a particularly low ground pressure
The ground pressure
of an Ml Abrams tank weighing 136,000 lbs., for instance, is around 15 pounds per square inch (psi) because of its broad track system.
The model features kinetic energy threat protection (360-degree B7), blast threat protection (front wheel Stanag 2A, rear wheel and centre undercarriage front wheel, Stanag +1), blast seats and mats, transparent armour (B7-ballistic protection level), higher ground clearance and wheel travel, larger tyres for increased traction and reduced ground pressure
, significant ride improvement, increased approach and departure angles, - Anti-Lock Brake System, Electronic Stability Control, traction control and an autonomous break control interface.
With those narrow tyres and two five-gallon drums of oil in the back, adding a bit of weight and applying more ground pressure
, I went about my business with barely a hitch, limited only by the old 10hp side valve engine, which lacked a bit of power.
"The track configuration of the Vactor Paradigm vacuum excavator is ideal for pipeline applications where significant ground pressure
may cause damage to buried infrastructure," said Schmidt.
With a ground pressure
of just 7.9 psi, the RT14R travels easily through sensitive terrains to reach remote pipeline projects.
System Fondaline Fondaline, made of high density polyethylene is used for draining of groundwater and protection of underground waterproofing systems against damages caused by ground pressure
The two biggest technical challenges Supacat faced were designing the vehicle to maintain a low ground pressure
and designing the equipment to withstand treacherous sea conditions.
This is a great benefit as this reduces ground pressure
The wide stance of the Terex crane and use of heavy-duty, 5m-long x 2.8m-wide x 0.36m-thick thick steel matting helped GHHL's operators meet the project's ground pressure
