Our Methods

EQ Renew, Inc. is pleased to offer a program for remanufacture of Parallelogram Lift equipment to better than new condition. This program is not a “refurbish” effort that rebuilds equipment on site and calls it “Remanufactured”. The entire lift system, including controls and accessories, is returned to a factory where a complete remanufacturing process takes place. This allows for the proper quality control and required lift upgrades to be put in place, to bring a level of quality that simply cannot be achieved in a field setting. This approach, coupled with a factory-supervised installation program, will ensure many more years of dependable service, and the remanufactured units should last longer than the originals, if properly cared for.

In addition to delivering a higher quality lift system than the original, a considerable cost savings can be realized when considering remanufacturing over replacement. Design and construction costs related to installing a system from a different vendor can amount to well more than the cost of the lift itself. These costs are eliminated from the process, as in most cases, the same equipment removed from the facility is reinstalled in the facility.

So, what is the EQ Renew Remanufacturing Program? Over the years, we’ve learned a few things regarding what needs to be upgraded or re-engineered, and with hindsight being 20-20, we offer the following program:

Field Evaluation

Before a lift can be remanufactured, the “core” must be evaluated to determine if the unit is suitable for remanufacturing. For those who have been involved in the vehicle maintenance industry, the process of using “cores” is nothing new. Cores have been used for decades to remanufacture everything from axles to air conditioners. In most cases, the structural elements are well within allowable tolerances to be used for remanufacturing, and if not, provision will be made to repair the structural elements or replace the deficient elements.

The existing system is evaluated at the customer facility using an extensive protocol and a variety of methods including, but not limited to, the following:

Visual inspection of all structural elements, including checks for straightness, weld integrity and structural damage.
Thickness measurements of structural elements using standard measuring tools.
Checks for compromised structural integrity due to corrosion using visual and ultrasonic testing.
Function testing to evaluate the condition of the hydraulic cylinders, pivot tubes, mechanical locks and anchorage.
Checks to determine the “Vintage” of the system, including number of lock positions, pins sizes, anchor size and pattern, hydraulic configuration of the control system, etc.

Proposal Process

Once the condition and vintage of the existing unit is determined, a firm price for remanufacture can be established based upon the number of operations that must be performed to bring the unit up to standards. For example, there are many early units in the field, that have no provision for pivot bushings, and all pivot tubes must be precisely bored to accept the required bushings. Later units had some provision for pivot bushings and need less precision machining, and therefore cost less to remanufacture. Other factors that can affect the cost of remanufacture are the distance from the factory and the options chosen in addition to the standard remanufacturing upgrades. Such options may include galvanized structural elements, stainless components, LED light packages, longer approach ramps, etc.

Once an agreement has been reached to remanufacture the equipment, the following program steps are taken:

Adjustment and Final Inspection

After assembly, each unit undergoes a final adjustment and function test for operation to ensure the unit will perform as advertised once it is returned to the customer.

Packing and Shipping

Each unit is carefully packed and loaded onto the truck of a carrier carefully selected by EQ Renew. These carriers have transported these units for years and are very familiar with the requirements of the assignment. Each lift is treated with care to be delivered in excellent condition.

Reinstallation

Once the remanufactured unit arrives on site, a factory trained representative will inspect the lift unit and accessories while still on the truck, supervise unloading and inventory the truck contents to ensure order completeness. The lift unit will then be reinstalled and tested to factory specifications.

Finally, customer personnel will be trained in the proper use of the product, maintenance personnel will be instructed in the care of the product, and the owner’s, parts and maintenance manuals will be left with the customer for future use.
