Description
Lifting an engine is a slow conversation between a pump handle and a hydraulic cylinder. Add a second power source and the conversation gets shorter. The Long Arm is an 8-ton long ram jack that runs on either shop air or a manual hydraulic pump, so the same cylinder handles a repetitive day in a busy bay and a delicate alignment job where millimetres matter.
Connected to an air compressor, it lifts on a trigger, which suits the repeated drivetrain pulls that fill an auto shop schedule. Switched to the manual pump, it makes fine adjustments under load so an engine and transmission can be lined up before the mounts are tightened. The cylinder carries 8 tons, roughly 17,600 pounds, and adjusts across 26.8 to 45.7 inches to suit most shop cranes and garage jacks without extra adapters.
The internals are built for a working garage rather than occasional use. The rod is chrome-plated alloy steel to resist corrosion under repeated pneumatic cycling, and the sealing system is reinforced against dust ingress and oil leaks. Safety is handled twice over with a hydraulic relief valve plus an air pressure cutoff that prevent overload, and an adjustable air-release valve controls descent so lowering is slow and steady instead of abrupt. A quick-install clevis base fits most engine hoists, and the same cylinder serves farm tractors, construction rigs, and warehouse machinery.
Gravity is patient. So is a good cylinder.

Where It Belongs
Engine and transmission removal in automotive workshops, farm tractor repair, construction equipment maintenance, and warehouse machinery handling where a crane needs a long reach cylinder. The pneumatic mode suits high volume shops, while the manual pump is the mode for alignment work where the load has to move slowly and stop exactly where it is put.
Frequently Asked Questions
Q: How much can it lift?
The cylinder is rated at 8 tons, about 17,600 pounds, which covers truck engines, tractor components, and industrial machinery within that limit.
Q: Does it need an air compressor?
Air is one of two options. Connected to a compressor it lifts on a trigger for fast repetitive work, and the manual hydraulic pump gives fine adjustment when you need precision instead of speed.
Q: What height range does it cover?
It adjusts from 26.8 to 45.7 inches, which fits most shop cranes and garage jacks without additional adapters.
Q: Is descent controlled?
Yes. An adjustable air-release valve allows slow, wobble-free lowering, which matters when a loaded engine is coming back down.
Q: How is overload handled?
Two mechanisms are fitted: a hydraulic relief valve and an air pressure cutoff switch, so the cylinder has protection in both operating modes.
Q: Will it fit my engine hoist?
The quick-install clevis base is designed to fit about 90 percent of engine hoists. Send us your hoist model and we will confirm compatibility before dispatch.
Q: How should it be maintained?
Keep the chrome rod clean and lightly oiled, check the hydraulic fluid level periodically, and inspect the seals for weeping if the unit runs on air every day. Store it with the ram retracted to protect the rod surface.
The EastSupplier Promise
Every cylinder is checked before dispatch and shipped with tracked international delivery in protective packaging. Because hoist fitment and compressor setups vary, our team confirms the clevis mounting and air supply arrangement before the unit ships, and spares advice is available after delivery.
