VRT350H Top Drive

The Victory Rig Equipment Top Drive is the first in a family of superior drilling machines. A dedicated team of seasoned topdrive designers and operators have cooperatively developed a machine that has been fundamentally improved in almost every aspect. The VRT350H is a hydraulically powered topdrive suitable for both portable and permanent applications. It is a compact, powerful machine that can even be installed on small workover and portable rigs..

The top drive system is a seamless combination of proven features, such as Driller's Panel control of all drilling functions and also control of pipehandler tasks. The topdrive incorporates and integrated swivel, and a novel arrangement of swivel bearings that enables a full 300 T pulldown capacity while rotating! Every aspect of the system has been reworked to improve reliability, serviceability, and especially ease and speed of rig in and rig out. Crew safety was a top priority in the design and development of the new system. Patents have been filed on several new features, including a quill/load sub connection that is an order of magnitude more robust than everyone else's, and a back up wrench die holder that is able to sense and release the tool joint if someone inadvertently tries to hoist with the Backup wrench.

Specs and Information

Premium materials and components have been used throughout the system to minimize downtime. Rineer hydraulic motors have been selected based on their outstanding robustness and reliability in the drilling environment. The Driller's Panel is an effortless joy to troubleshoot. Every panel element has built-in self diagnostics, and they are all connected with ribbon cable to ensure the elimination of loose connections. When all components are ok their indicator lights show green. When a component fails it shows red and can be replaced in about a minute. No more hours of frustrating multimeter adventures or waiting for an electrician!

Another time-saving feature of the pipehandling system is adjustable elevator bails. Rather than having to change to longer bails and swap over link tilt mechanisms, all VRT topdrives come with extendable bails.

Geared Hydraulic Drive

Two Rineer single stack 125 cubic inch code 62 (5000 psi) motors, each driving its own pinion and the bull gear. The final reduction ratio was chosen by the peak torque that the topdrive will require using 125 cubic inch motors. Final configuration of the gearbox has been set. The gearbox specifications are as follows:

Gear ratio 2.48 reduction material

Pinion 9310 carburized

Bull Gear 8620 carburized

Life Expectancy >>1 million hours

Hydraulic Power Unit

Redundant electric motor pump drives:

Topdrive can operate with either of the pump drives shut down for economy or maintenance.

Two AC induction motors, 300 hp at 1750 rpm

Two piggyback swashplate pump groups

Each group has a 250 cc and a 100 cc Sundstrand pump

Each motor/pump group can produce 161.5 gpm

Total closed loop pump system can produce 323 gpm

The system is designed to maximize performance and minimize flow losses.
