Service Trucks International

What Service Trucks International does

Service Trucks International, Ltd. (STI) is a privately held US manufacturer of custom service truck bodies and telescoping boom cranes, headquartered in Sioux Center, Iowa. The company operates two integrated product lines — STI Service Bodies, built for chassis from 10.5K to 33K GVW in six configurations (1540, 2244, 2250, 2460, flatbed, and propane variants), and Tiger Cranes, a 35-year-old sub-brand offering 13 telescoping models in electric-over-hydraulic and full-hydraulic formats with lift capacities from 2,000 to 14,800 pounds and reaches from 5 to 30.5 feet. STI's Tiger Cranes line was established in 1989 through the acquisition of Pacific Crane of Oregon assets, and cumulative Tiger Crane production passed 10,000 units in 2025. Differentiated mechanical features include Auto II Speed load-sensing control, sealed turret design, sequential boom cylinders with measurement indicators, hex boom profile, cabinet pressurization, and 3-point compression door locking.

STI generates revenue primarily through hardware sales (service bodies, Tiger Cranes, and replacement parts) supplemented by professional services (DOT inspections, repair, remounting onto new chassis, and reconditioning). Pricing is quote-based and not publicly disclosed; distribution runs through an authorized US distributor network supported by six regional sales managers and a National Sales Manager covering distinct US territories, with pre-built work-ready inventory available for immediate delivery. The customer base is horizontally distributed across construction (primary), agricultural equipment service, municipal utilities, inland marine/waterways, and propane/natural gas end markets. The company employs 101-250 people across two Sioux Center facilities, is privately held with no disclosed external institutional ownership, and is currently investing in a new dedicated Tiger Crane manufacturing plant, expanded customer support, and ongoing product redesigns.

Broad incumbents

• Palfinger: Palfinger is a global lifting solutions manufacturer with truck-mounted knuckle boom and telescoping cranes that compete with Tiger Cranes in the service crane category. While their core focus is larger loader and knuckle boom cranes, they overlap with STI in mid-range service crane applications.
• Knapheide: Knapheide is one of the largest commercial truck body manufacturers in North America with a broad portfolio spanning service bodies, utility bodies, platform bodies, and upfits. As a much larger incumbent, Knapheide competes with STI on the service body side while also offering crane integration through partner relationships.

Direct peers

• JOMAC: JOMAC builds custom service trucks with integrated cranes and utility bodies, directly comparable to STI's body+Tiger Crane packages. They serve similar municipal, utility, and construction fleet customers with crane-equipped service vehicles.
• Iowa Mold Tooling (IMT): IMT is a direct competitor in truck-mounted service cranes, compressors, and lubricators, serving the same construction, agriculture, and utility fleet operators as STI. Their product portfolios overlap heavily in telescoping and articulating service cranes for service truck applications.
• Stellar Industries: Stellar Industries (Garner, Iowa) manufactures service truck bodies, hydraulic and electric service cranes, and material handling equipment - directly overlapping STI's combined body and Tiger Crane product lines. Both companies target similar vocational fleet customers in construction, utilities, and agriculture.
• Reading Truck Body: Reading Truck Body designs and manufactures commercial work truck bodies including service and utility bodies. They serve similar fleet customers in construction, utilities, and municipalities, and compete for the body portion of integrated crane truck specifications.
• Royal Truck Body: Royal Truck Body manufactures custom service and utility truck bodies with crane mounting capabilities, serving similar construction, utility, and municipal fleet markets. Their product offerings overlap directly with STI's service body line for vocational fleet applications.
• Maintainer Corporation: Maintainer Corporation (Sheldon, Iowa) manufactures integrated service truck bodies with cranes - a near-identical product concept to STI's body+Tiger Crane combination. Both Iowa-based manufacturers compete for the same construction and utility fleet customers with crane-equipped service trucks.
• Auto Crane Company: Auto Crane (Tulsa, OK) manufactures electric and hydraulic truck-mounted service cranes with similar lift capacities and reach profiles to Tiger Cranes. They sell to the same truck body builders and fleet operators, making them one of STI's closest direct competitors in service cranes.

Emerging players

• Versalift: Versalift specializes in aerial lift (bucket truck) equipment mounted on commercial chassis, adjacent to STI's crane-equipped service trucks. While their core focus is aerial work platforms rather than telescoping service cranes, they overlap with STI in the work truck mounted equipment space serving utility and municipal customers.
