Murphy adds electric diggers to its fleet: deployment notes for urban project teams

30 Second Briefing
Civil engineering contractor Murphy has added two 23‑tonne Sany SY215E excavators to its fleet, each powered by cobalt‑free lithium iron phosphate batteries from CATL. Sany states the machines deliver six to eight hours of operation with rapid charging to 80% state of charge in about one hour, enabling a full shift with a single mid‑day top‑up on many urban or constrained sites. The zero‑tailpipe‑emission units are likely to be deployed where air quality limits, noise constraints and low‑carbon client requirements are tightening.
Technical Brief
- Murphy’s two new units are Chinese-built Sany SY215E 23‑tonne crawler excavators.
- Traction energy storage uses CATL-manufactured cobalt‑free lithium iron phosphate (LFP) battery packs.
Our Take
Murphy’s move into battery-electric 23‑t excavators aligns with its role on major UK schemes like the Lower Thames Crossing, where contractors are under pressure from National Highways and Treasury scrutiny to demonstrate tangible emissions reductions on plant-heavy packages.
Sany’s growing UK footprint, highlighted by TH White’s recent appointment as an authorised Sany Heavy Machinery UK dealer, suggests Murphy will likely have improving local support and parts availability for these Chinese-built electric machines, which is often a concern on early low-emission kit.
Using CATL battery systems ties Murphy’s fleet decarbonisation to cobalt-dependent supply chains in China, which may become a procurement and ESG talking point as more of the 408 Infrastructure stories in our database touch on battery material sourcing and lifecycle impacts.
