ESCO YAK 44/22 Ton Air/Hydraulic Portable Jack

The YAK 92005 features dual-stage lifting capacity rated at 44 tons primary stage and 22 tons secondary stage (40/20 tonnes metric). This dual capacity allows flexible lifting configurations - use the 44-ton capacity for single-stage applications or 22 tons for dual-stage lifts. Always verify vehicle weight specifications before lifting, and never exceed the rated capacity regardless of vehicle size. The jack is designed specifically for heavy vehicles including trucks, commercial vehicles, and emergency service equipment.

The minimum height when fully retracted is 3.5 inches (89 mm), making it one of the lowest-profile portable jacks available. This ultra-low profile enables access under vehicles with severely restrictive ground clearance that traditional floor jacks cannot fit under. The jack extends to a maximum height of 13.81 inches (351 mm) with a 6.7-inch stroke, providing adequate vertical lift range for most tire service, brake work, and suspension access on heavy vehicles and commercial equipment.

Yes, the YAK 92005 operates on 116-145 PSI (8-10 bar) air, making it compatible with vehicle-mounted air compressors on heavy trucks and commercial vehicles. This vehicle air compatibility is one of the key advantages for roadside service and emergency assistance operations - technicians can tap into the customer's vehicle air system to power the jack without requiring separate shop air infrastructure. Always verify the vehicle air system maintains adequate pressure within the 116-145 PSI operating range.

At 82 pounds (37 kg) with a removable handle, the YAK 92005 is specifically engineered for portability. One technician can easily transport the jack from a service vehicle to the work location. The removable 37.8-inch handle reduces length for compact storage in service vans, emergency kits, and onboard vehicle storage. This portability makes the YAK ideal for mobile tire service, roadside assistance, and emergency response operations where equipment must be easily transportable.

The two independent descent valves provide precise control over lowering speed and prevent uncontrolled descent under all conditions. The dual-valve design guarantees perfect holding in all lift positions and controlled lowering speed under load - critical features for tire service and emergency roadside repairs where load stability cannot be compromised. If one valve experiences any issue, the second continues to hold the load safely, providing redundancy for operator and vehicle safety.

The YAK 92005 includes a 4.725-inch saddle extension (120 mm) for standard lifting, multiple 2.75-inch extensions (70 mm) for various vehicle saddle configurations, a 0.5-inch saddle pad (10 mm), and an extension holder for organized storage. These multiple extensions allow precise saddle point alignment on different vehicle types without purchasing additional equipment. Keep extensions organized in the included holder for quick access during service calls.

Yes, the YAK 92005 is specifically designed for roadside assistance and emergency service operations. The portable design, removable handle, vehicle air compatibility, and dual descent valve security make it ideal for AAA, towing services, mobile repair, and fleet emergency kits. Technicians can carry the jack in service vehicles, use existing vehicle air systems for power, and confidently perform tire service and vehicle recovery operations at customer locations without shop infrastructure.

The YAK 92005 requires minimal maintenance. Inspect external components monthly for leaks, cracks, or damage. Verify dual descent valves operate smoothly at mid-lift position. Ensure shop or vehicle air supply includes moisture trap and pressure regulator. Keep saddle points clean and lightly lubricated. Store in a clean, dry environment between uses. Before each service cycle, verify all extensions are present and in good condition. Replace or clean air filters according to air system maintenance schedules.

The YAK 92005 portable jack trades some vertical lift range for exceptional mobility and transportability. It's superior to stationary lifts for mobile operations, roadside service, onboard vehicle storage, and emergency response where equipment must be easily moved between locations. Stationary floor jacks and two-post lifts excel for high-volume shop operations requiring rapid vehicle turnover, but cannot be transported. The YAK 92005's 3.5-inch minimum height also accesses vehicles that stationary lifts cannot reach.

No, professional safety standards require secondary support at all times. Always position safety jack stands or equivalent secondary support equipment alongside the YAK 92005 before beginning any service work underneath a vehicle. Use the jack for lifting and positioning, then engage mechanical jack stands before working underneath. This redundant support provides critical protection if the primary jack malfunctions or experiences unexpected pressure loss.

ESCO backs the YAK 92005 with a 3-year limited warranty covering all hydraulic components, pistons, descent valves, and structural elements against manufacturing defects. Warranty requires the jack be used within rated capacity and operated according to the instruction manual. Keep your receipt and warranty registration documentation. Normal wear items like seals are excluded, as are damages from misuse, overload, or unauthorized disassembly. Contact ESCO directly for warranty claims and service support.

Yes, the YAK 92005 is suitable for tire replacement, brake service, suspension work, undercarriage inspection, and emergency vehicle recovery. The dual descent valves and automatic piston retraction make it reliable for extended service procedures. The ultra-low 3.5-inch profile enables access under vehicles with restrictive clearance. Always position secondary jack stands alongside the jack before performing any work underneath a vehicle, regardless of the service task.
