PatLoc Safety Systems PatLoc Safety Systems delivers engineered ground-level pawl control for pumpjacks. 700× Faster LOTO. Zero climbing. Zero exposure. Field-proven for over a decade.

Safety that protects crews and drives real ROI in oilfield operations. The PATLOC Safety System is the only product available engineered to engage and disengage the pawl from the ground – out of harm’s way and locking the pump using a single individual. Our system properly secures pump jack units safely for employees and contractors when needed. Available for Weatherford and Lufkin models, with Patloc Safety System installed, you'll save time and money and reduce risk of accidental injury to almost zero.

There is a design argument for keeping safety-critical field equipment purely mechanical. Sensors fail. Batteries drain. Firmware becomes obsolete. Signal paths degrade in the presence of dust, temperature swings and moisture, all standard conditions on a producing lease.

PatLoc's actuation system uses none of those. The result is a piece of equipment that behaves identically at -30°F and 120°F, in a Wyoming winter and a West Texas summer, on year one and year ten.

Mechanical simplicity is not a limitation. On a pumping unit, it is the point.

What PatLoc changes:

• The operator's physical position during pawl actuation
• The line of sight to the pumping unit while engaging the pawl
• The consistency of the actuation motion across crews

What PatLoc does not change:

• The brake as primary motion control
• The pawl as the secondary locking mechanism
• Chain, binder or any other required mechanical restraint
• The site's existing LOTO procedure

A useful addition to the field is one that fits, not one that reorganizes everything around it.

Most safety improvements in the oilfield ask the crew to add a step, adopt a new tool or memorize a new protocol. PatLoc is designed to do none of those things.

It is a mechanical assembly, clamped onto the pumping unit, that transfers the operator's actuation of the pawl to a ground-level handle. The pawl itself does not change. The brake does not change. The LOTO sequence does not change. The operator's position changes, from working at elevation, near the brake drum and counterweights, to working at ground level with the equipment in full line of sight.

That is the entire premise. Small change in position. Meaningful change in exposure.

Five points describe how PatLoc integrates with a pumping unit:

1. Installed as a clamp-on assembly. No welding, no hot work, no unit modification.
2. Positioned so the operator remains at ground level for the actuation task.
3. Actuated through a mechanical linkage that drives the existing pumping unit pawl.
4. Verified visually, the operator can confirm pawl engagement before proceeding.
5. Integrated into whatever LOTO sequence the site already runs. No procedure rewrite.

What changes is where the operator stands. What does not change is anything else about the unit's safety architecture.

On many beam pumping units, the answer is: on the unit itself.

Near the brake drum. Near the counterweights. Above ground.

That physical position is one of the clearest indicators of exposure on any servicing procedure, and one of the most rarely re-examined.

Worth revisiting.

Three questions worth asking of every LOTO procedure on your fleet:

→ Is the pawl seating visually verified, not just assumed?
→ Is brake application confirmed before mechanical restraint is applied?
→ Is each step recorded in a way another crew could audit tomorrow?

A procedure that fails any of these is a procedure that depends on the individual instead of the system.

Message us to discuss how your crews document pawl verification today.

A pawl seated under load is a pawl bearing forces it was never designed to absorb.

The brake exists to hold the load first. The pawl is then set into an already-restrained system.

Reverse the sequence and you place the operator between stored energy and an undersized restraint. The procedure exists for a reason.

Every layer of the pumping unit safety hierarchy has a distinct engineering function.

The brake dissipates and holds motion, it is the primary control surface for stopping the walking beam and preventing rotation of the crank arms.

The pawl provides a secondary mechanical lock at the brake drum, catching motion the brake is already holding.

Chain and binder introduces a tertiary mechanical restraint where site procedure or configuration requires it, a physical barrier against unintended movement.

Each layer earns its place. None replaces another.

Lockout / Tagout (LOTO): the OSHA-recognized framework for isolating hazardous energy before servicing equipment.

The common misreading - LOTO equals a lock and a tag.

The engineering reality - LOTO is a sequenced procedure that combines motion control, secondary locking, mechanical restraint and verification, each layer selected for the specific equipment and energy source being isolated.

On a beam pumping unit, no single device performs the whole job. Treat it accordingly.

The pawl explained in three points:

1. It is a mechanical locking element that engages the brake drum to help restrain motion during servicing.

2. It is a secondary safeguard, the brake remains the primary motion-control device on the unit.

3. It works alongside, not instead of, any additional mechanical restraint (such as chain and binder) that the site's LOTO procedure calls for.

Understanding where the pawl sits in that layered system is what separates procedural compliance from actual field safety.
