Wastewater Plant Builds a
Multi-Station Lifting Network.
A new wastewater treatment facility needed to lift pumps at every station in the plant — tighter budget than a permanent overhead crane at each station, less operator strain than a heavy portable rig at each lift point. eme installed side-mount sockets on the tank wall at every station and supplied one lightweight GEN II davit crane to service the entire network. More sockets, fewer cranes, every lift point covered.

Pump Service at Every Station in a New Treatment Facility.
The facility was a new build with multiple wastewater process stations, each carrying its own pumps. Every station needed a rated way to lift pumps for service — change-outs, impeller cleaning, motor swaps, scheduled inspection cycles. Without a permanent overhead crane at each station and without a budget that would let the plant install permanent cranes everywhere, the operator needed a lifting solution that scaled with the facility.
Tighter Budget. More Lift Points. Less Operator Strain.
The plant's brief was specific: be more efficient on a tighter budget, with less stress on the operators. The traditional answers — a permanent overhead crane at every station, or a heavy portable rig hauled around the facility — each failed one of those tests. A permanent crane at every station exceeded the budget. A heavy portable rig hauled station-to-station produced operator strain and slowed every service cycle. The operator needed lift coverage at every station without the capital cost of permanent cranes and without the daily handling burden of heavyweight portable equipment.
Side-Mount Sockets at Every Station. One Lightweight Davit Across the Network.
eme installed side-mount sockets on the tank wall at every pump station in the plant — safety-yellow, permanently mounted, Smooth Glide engagement. A single eme GEN II davit crane — lightweight aluminum construction at 38–43 lb depending on the model — handles the lift at any station. When pump service is due, an operator carries the davit to the station, drops it into the socket with zero tools, rotates under load, completes the lift, and moves the davit to the next station as needed.
The architecture inverts the usual question. Instead of "how many cranes do we need?" the question becomes "how many sockets do we need?" — and the answer scales linearly with the plant, not with the number of cranes. As the plant expands or adds new pump stations, eme installs new sockets; the existing davit covers them all.
Permanent Lift Points at the Cost of Fixtures. One Davit Covers Them All.
- Sockets cost less than cranes per lift point. A side-mount socket is a permanent, rated fixture. Installing one at every station costs a fraction of installing a crane at every station — and the network only needs one davit to service them all.
- 38–43 lb davit. Light enough for one-person handling in many applications. The GEN II davit is light enough that an operator picks it up, walks it to the next station, and drops it into the socket with zero tools. Operator strain drops; service cycle time drops.
- Scales as the plant grows. When the facility adds a new pump station or expands process capacity, eme installs another socket. The existing davit covers the new station without an additional crane purchase.
- Permanent, documented lift points for plant safety review. Each socket is engineered, installed, and visibly identifiable as a designated lift point — simplifying internal safety reviews and recurring maintenance planning.
- The lifting-network architecture eme is now known for. This wastewater plant project is the foundation of the eme socket-network value proposition: don't replicate the crane, replicate the lift point. One davit, many sockets, every lift point covered.
