Tranzsporter Liftan Engine TP400 TP250

Description

Roofing hoist motor failures strand heavy shingles on flatbed trailers and halt roofing crews. Installing the Tranzsporter Liftan Engine TP400 TP250 replacement engine restores hoisting capability to TP400 and TP250 ladder hoists. Delivering dedicated power for 400-pound lift ratings, it pulls shingle bundles with steady speed. The specialized mounting base restricts installation to Tranzsporter hoist carriages.

Constructed for roofing platform winches, this engine uses a cast-iron cylinder sleeve housed within an aluminum block to manage rapid heat buildup during continuous hoisting cycles. The valvetrain features overhead valves to enhance fuel combustion and exhaust scavenging. A reinforced recoil starter assembly withstands aggressive pulls by roofing laborers, while an integrated oil alert sensor prevents ignition if the engine tilts past safe limits on steep pitched roofing setups.

Roofing Hoist Hardware Matrix Data

Residential and commercial roofing contractors require dependable hoisting power to move tons of asphalt shingles onto rooftops. This replacement power unit bolts onto ladder hoist tracks.

• Direct-fit replacement engine powers Tranzsporter TP400 and TP250 roofing ladder hoists without fabrication.
• 400-pound maximum lift capacity hoists bundles of shingles, rolled roofing, and plywood sheets.
• Overhead valve engine architecture delivers fuel efficiency and cooler operating temperatures on hot roofs.
• Cast-iron cylinder sleeve provides bore durability during continuous material lift duty.
• Heavy-duty recoil rewind starter provides dependable manual ignition without requiring external batteries.
• Integrated low-oil shutdown sensor halts engine operation before oil starvation damages internal bearings.
• Pre-drilled hoist bracket mounting pattern enables fast changeouts on active commercial jobsites.

Hoist Lift Dyno Telemetry Data

Hoist test stand pulls evaluate cable drum torque and engine thermal limits under continuous shingle lifting cycles. Hoisting 400 pounds on the TP400 track at 110 feet per minute draws a continuous 3.8 horsepower load, burning 0.44 GPH regular gasoline. Sump oil temperature climbs to 210°F during two hours of continuous hoisting trials in 90°F sun. Mechanical torque sustains steady drum speed without engine bogging. Sound meter testing measures 83 dBA at 7 feet during active hoisting.

Field Service Maintenance Boundaries

Roofing worksites expose engines to fiberglass shingle dust and granules. Do not operate this hoist engine when tilted past 15 degrees on ladder rails, as oil alert sensors will trip and kill ignition mid-lift. Avoid using old contaminated fuel left over from previous roofing jobs.

• Change engine oil every 50 hours of active shingle hoisting.
• Inspect and clean the foam air cleaner element every 20 operating hours.
• Check hoist base mounting clamp bolts every morning before lifting materials.
