When a lift gearbox begins to fail, lift service providers are often faced with a tough decision: should you overhaul the existing machine or replace it entirely? The right choice depends on a variety of factors, including cost, lead times, and the specific requirements of the client's site.
Here is a breakdown of when a root-cause overhaul is the more cost-effective and faster option compared to sourcing a new machine.
The Case for Gearbox Overhaul
1. Faster Turnaround Times
Sourcing a brand-new lift machine can involve significant lead times, especially if the unit needs to be custom-built or shipped internationally. In contrast, a comprehensive gearbox overhaul can often be completed much faster. At EES Vertical Transportation, our precision machining capabilities allow us to remanufacture obsolete or hard-to-find components, getting the lift back into service quickly.
2. Cost-Effectiveness
A full machine replacement is a major capital expense. Overhauling the existing gearbox—replacing bearings, re-cutting gears, and fitting new seals—can restore the unit to OEM standards at a fraction of the cost. This is particularly appealing for clients looking to extend the lifespan of their equipment without a massive layout of funds.
3. Minimizing Structural Modifications
Installing a new machine often requires significant modifications to the machine room bedplates and structural supports to accommodate different dimensions and mounting points. An overhaul allows you to retain the existing footprint, eliminating the need for costly and time-consuming structural rework.
When Replacement Makes Sense
While overhauls are highly effective, replacement may be necessary if the gearbox casing is catastrophically damaged, or if the client is undertaking a full modernization project to upgrade the entire lift system to the latest technology.
