Product Types – Vertical Lifting Solutions Portfolio

Our vertical lifting solutions cover the full spectrum of well intervention lifts:

Hydraulic Rod Pulling Unit (VLS‑20/50) – Lightweight, trailer‑mounted for sucker rod replacement. Used on beam pump wells. Fast set‑up (under 1 hour), one‑person operation.
Tubing Workover Unit (VLS‑50/100) – For pulling tubing strings in conventional or slightly deviated wells. Includes mast, dual lift cylinders, and hydraulic catwalk option.
Snubbing Unit (VLS‑100/150 with jack) – Live‑well workover against pressure. Combines vertical lift cylinders with a snubbing jack stack. Runs or pulls pipe without killing the well.
Hydraulic Platform Lift (VLS‑150/200 skid) – Fixed installation on offshore platforms or central facilities. No road transport – just bolt to the deck. Used for routine well maintenance.
Truck‑Mounted Vertical Lift (VLS‑50/100) – Mast and HPU permanently mounted on a heavy truck chassis. Self‑propelled, ideal for multi‑well campaigns within a small geographic area.
Standalone Hydraulic Lift Cylinder – For customers who already have a mast and only need the lifting power. We supply the twin cylinders, control valve, and HPU to retrofit into your existing structure.
Portable Foundation Lift – For temporary wells or exploration sites. The mast and cylinders mount on a steel foundation beam that sits directly on the ground. No trailer, no truck – just a flatbed drop.

Applications – Where Our Vertical Lifting Solutions Are Used

Our vertical lifting solutions have been deployed in:

Rod pumping well maintenance – Replacing broken or corroded sucker rods. The VLS‑20 pulls 1‑1/4" rods from 5,000 ft depths in minutes.
Tubing changeout in older fields – Many wells require tubing replacement every 5‑10 years. Our VLS‑100 handles 2‑7/8" tubing strings up to 10,000 ft.
Live‑well snubbing (high‑pressure gas wells) – Using the VLS‑150 with a 5,000 PSI snubbing jack. Operators avoid killing the well (which can damage low‑pressure reservoirs).
Platform well intervention – Offshore platforms in Southeast Asia use our skid‑mounted VLS‑150 for routine scale removal and pump changes. Compact footprint fits between other equipment.
Arctic winter workovers – The VLS‑100 with cold‑weather package operates at -40°C. Heated cab and hydraulic fluid keep the system ready.
Remote desert well servicing – A trailer‑mounted VLS‑50 with diesel HPU can be towed by a 4x4 pickup. Minimal ground preparation.
Abandoned well plug and pull – Heavy pulling (up to 200 tons) to extract stuck packers or corroded casing strings. Our VLS‑200 provides the force needed.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a vertical lifting solution and a conventional workover rig?
A conventional workover rig uses a winch and wireline – it is simpler but has less control, cannot snub against pressure, and has higher drift (load creep). Our vertical lifting solutions use hydraulic cylinders: infinite variable speed, positive load holding, and live‑well snubbing capability.

Q2: Can I use your vertical lifting solution for snubbing without buying a separate unit?
Yes – our VLS‑100, 150, and 200 models can be ordered with an integrated snubbing jack. The same lift cylinders raise and lower the jack. You do not need a second machine.

Q3: How long does it take to set up a trailer‑mounted VLS on a well site?
Two crew members: 1.5‑2 hours from pulling the trailer into position to being ready to lift. This includes leveling the trailer, extending the mast, connecting hydraulic hoses, and testing the safety systems.

Q4: Do you provide load test certification?
Yes – every vertical lifting solution is load‑tested to 125% of rated capacity at our factory. We provide a signed test certificate. For offshore use, we can schedule witness testing by ABS or DNV.

Q5: Can your system be powered by the rig’s existing hydraulic unit instead of a separate HPU?
Possibly – if your rig’s HPU has enough flow (GPM) and pressure (PSI) to match our cylinders. Send us your HPU specifications (flow rate, pressure, fluid type) and we will calculate compatibility.

Q6: What safety features are standard?
Every system includes: overload protection (relief valve), emergency stop pendant, hydraulic counterbalance valves (fail‑safe lock), and hoses with burst‑resistant rating. Snubbing models add a manual lock for the slip bowls.

Q7: Can I get a system with remote telemetry to monitor lifts from my office?
Yes – for VLS‑100 and above, we offer a telemetry package. The PLC records each lift’s load vs. depth and sends a summary to your email or server. You can monitor job progress without being on site.

Q8: What is the typical life of a hydraulic lift cylinder?
With proper maintenance (seal replacement every 3‑5 years), the cylinders last 15‑20 years. The rods can be re‑chromed if they get scratched. We keep seal kits and replacement rods in stock.

Q9: Do you offer rental units for short‑term projects?
Yes – we have a small rental fleet of VLS‑50 and VLS‑100 units available for 30‑day minimum rental. Contact our rental desk for availability and rates.
