Safe-T-Driver ® Hoist with ¼-inch (6.4mm) Cable

Safe-T-Driver ® Hoists - are available from USExploration Equipment Company as an alternative to a cathead for SPT sampling operations.

The simple design allows the operator to raise and lower a safety hammer assembly 30-inches (762mm) - attached directly to the ¼-inch (6.4mm) cable that is spooled on the drum itself.

The handle at the panel allows the operator to control the lift (visually), then pull the same lever down, pushing enough oil through the system to an over-running clutch attached to the hoist drum, creating a free-fall “action” for the 140-pound (63.5 kg) weight as part of the requirements for ASTM-D-1586-99  in every state.

This same hoist can be used to “bump-out” when required, unlike other automatic or semi-automatic driving devices.

The field kit includes a hand brake when conditions require it – simply specify the rig make and model when ordering.

140-Pound (63,5kg) SPT Automatic Hammer Assembly

SPT Automatic Hammer Assemblies - are available from USExploration Equipment Company.

They give you extremely consistent and accurate Standard Penetration Test (SPT) results, meeting all ASTM-D-1586-99 requirements in every state.

These assemblies can be adapted to virtually any 5-foot stroke machine because the hammer simply swings in from a “stored” position to the “on-hole” position.

Since raising and lowering is done hydraulically, set up is quick and almost effortless.

For maximum safety, all moving parts are enclosed, including the impact area between the weight and the anvil.

Each assembly includes a Hammer Case, Slug, Hydraulic Cylinder, Hydraulic Motor, Guide and Sub.

When ordering, specify the make and model for the rig installation and hydraulic circuitry you intend to use.

AWJ Full-Swivel Hoisting Plug (top) and AW/ AWJ Rod “Slip” Ring (bottom)

Hoisting & Rod Handling Tools for J-Series, W-Design & API style Drill Rods – are available from USExploration Equipment Company.

Full-Swivel style Hoisting Plugs and Rod (Slip) Rings are all DCDMA compatible.

When ordering, simply choose the appropriate thread style and corresponding tool for your application.

140-Pound (63.5 kg) In-Hole Hammer Assembly with Swivel and AW Box Down

140-Pound (63.5 kg) Safety Style Hammer Assembly with Cast Anvil  and AWJ Pin Down

Safety Type & In-Hole Style “SPT” Drive Hammers, Parts & Accessories – are available from USExploration Equipment Company.

Typically attached to the “business end” of a Cathead Rope or a Safe-T-Driver Hoist (free-spooling) cable, these tools are designed to help the operator complete ASTM Procedure D1586-08a along with the appropriate down-hole sampling device.

This test includes lifting and (freely) dropping a 140-Pound (63.5 kg) weight exactly 30-inches (762mm) on top of 1-3/4-inch (44.5 mm) Outside diameter (AW or AWJ) Drill Rods to achieve the correct “N” value as it relates to determining material density and proper foundation design.

The 300-Pound (136 kg) version is typically used to drive Flush Joint Casing through formations that are too difficult to advance Solid Stem or Hollow Stem Augers.

The In-Hole Style Hammer works best in conjunction with a Safe-T-Driver Hoist as the 2-7/8” (73mm) OD assembly can be lowered into Flush Joint Casing or Hollow Stem Augers, to advance a Sampler, break up material that has worked its way inside the annular space or simply act as an internal cutting face in addition to the Casing Shoe or Cutter head.

When ordering, make sure you specify Safety Style or In-Hole Hammer assembly

The simple clamping function allows you to adjust quickly to different casing diameters.

The precision machined (roller) axles assure a smooth straight pull without vibration - every time.

The Pump Pull-Assist clamps quickly & easily to a wide range of steel casing.

Tapered hard plastic rollers assure that the PVC, wires and pump come out of the casing easily.
