Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, delivering the same protective coverage as the part it replaces.
- Direct Bolt-On Fit — Engineered to align with the existing mounting points on ST-45HRM and ST-70 concrete pumps, making installation straightforward for any qualified technician.
- Confirmed Fitment — Verified for use on ST-45HRM and ST-70 swing-tube concrete pump models.
- Thermal Protection Where It Matters — Shields the heat exchanger from impact, debris, and jobsite hazards that can compromise cooling efficiency and lead to overheating.
- Operational Safety — Provides a physical barrier around a high-temperature component, reducing burn risk for operators and service personnel working in close proximity to the pump.
The heat exchanger guard on a concrete pump serves as a protective housing around the heat exchanger core, which is responsible for regulating hydraulic fluid temperature during pumping operations. Without adequate protection, the heat exchanger is vulnerable to physical damage from debris, concrete splatter, and accidental contact — damage that can cause fluid leaks or loss of cooling capacity, leading to hydraulic overheating and unplanned downtime. Keeping this guard intact and in good condition is essential to maintaining safe operating temperatures and protecting the hydraulic system over the long term.
