Buying used foundation equipment is mostly a question of knowing what to ask before you travel to see a machine. These guides set out the specifications that decide whether a machine suits your work, the wear points that decide what it will cost you, and the checks worth making before money changes hands.
What to check before buying a used foundation drilling rig: torque and depth ratings, kelly bar condition, mast and undercarriage wear, hours, and the paperwork that decides whether the machine can work where you need it.
Choosing a used hydraulic impact hammer: matching ram weight and energy to the pile, checking the power pack pairing, and the wear points that decide whether a hammer is a bargain or a rebuild.
What matters when buying a used vibratory hammer: eccentric moment and frequency, variable versus fixed moment, clamp condition, bearing life and carrier compatibility.
Assessing a used pile driving rig: leader configuration and rake, hammer compatibility, winch and mast condition, and the transport and setup constraints that decide whether it suits your sites.
Buying a used anchor or micropile rig: drilling methods, mast and feed configuration, restricted-access dimensions, rotary head condition and the hydraulic capacity that determines what the rig can drill.
Buying a used casing oscillator: matching casing diameter and torque to your piles, checking clamping cylinders and jaws, and why the hydraulic power pack decides whether the machine is usable at all.
What to check on a used diesel pile hammer: ram and cylinder condition, energy rating against your piles, starting behaviour, and the emissions and noise limits that decide where it can legally work.
Buying used casing tubes, augers, buckets and core barrels: matching joints and connections to what you already own, judging remaining wear life, and the compatibility checks that decide whether tooling is usable.
Choosing a used grout plant: matching mixer type and pump pressure to the work, checking wear parts, and the output and continuity questions that decide whether the plant suits jet grouting or anchor work.
Assessing used duty-cycle cranes, diaphragm wall grabs and hydromills: winch and rope condition, verticality control, tooling compatibility, and the transport constraints that dominate these machines.
Sizing and checking a used drilling air compressor: free air delivery and pressure against your DTH hammer, airend condition, aftercooler and filtration, and the emissions rules that affect where it can work.
