International Wireline Truck – Specifications & Overview

Manufacturer: International (Navistar)
Type: Heavy-duty service truck
Application: Wireline/logging, perforating, cased hole/formation evaluation, well work

Common International Chassis Used in Wireline Builds

International produces vocational and work-truck platforms ideal for customization:

• International HV (formerly WorkStar / 7400/7600 series) — rugged, high GVWR

• International LT / LT Series — highway capable with heavy payload

• International CV (formerly Durastar / 4000/4400 series) — mid-size work truck

• International 9900 / 9800 — classic highway chassis (less common for body work)

Most wireline trucks use HV/WorkStar or CV series for durability and payload.

Engine (Typical)

Heavy-duty diesel engines paired with International chassis:

• International A26

  • ~300–475 HP

  • ~200–450 HP

• Cummins ISX / X15 (on larger configs)

Engine choice depends on:

• Body weight

• Hydraulic loads
