SLT-660F – JET 14077 660 Lbs. Capacity Scissor Lift Table with Folding Handle
Available now on the Airparts.aero Marketplace.
The JET SLT-660F (Manufacturer Part Number 14077) is a high-utility, industrial-grade hydraulic scissor lift table designed for the precision handling of aircraft components, battery banks, and shop tooling. In an aviation maintenance environment, the SLT-660F serves as an ergonomic bridge between floor-level storage and workbench or airframe heights. With a 660 lb. lift capacity, it is specifically engineered to mitigate technician fatigue and prevent musculoskeletal injuries during the removal and installation of heavy line-replaceable units (LRUs), such as main aircraft batteries, starter-generators, or small piston engine cylinders.
Constructed from heavy-gauge reinforced steel, the SLT-660F utilizes a foot-operated hydraulic pump to achieve smooth, incremental vertical displacement. This "fine-feed" capability is essential when aligning heavy components with mounting studs or sensitive airframe interfaces. The integration of a folding handle allows for a minimized footprint, enabling the unit to be stowed under workbenches or within mobile maintenance trailers, maximizing hangar floor efficiency.
Key Features
Ergonomic Foot Pump: Features a high-ratio hydraulic pump assembly that allows for effortless lifting of maximum loads with minimal physical input.
Precision Overload Protection: Integrated bypass valve prevents the hydraulic system from exceeding its rated capacity, protecting both the operator and the sensitive aircraft components being lifted.
Folding Handle Design: Equipped with a quick-release folding mechanism, reducing the unit's vertical profile for compact storage or transport in service vehicles.
Polyurethane-on-Steel Casters: High-durability, non-marring wheels ensure low rolling resistance on hangar floors while providing excellent chemical resistance to Skydrol and fuel spills.
Dual-Wheel Braking System: Includes safety floor locks on the rear swivel casters to ensure a stationary, stable platform during component transfer or assembly work.

Applications
The SLT-660F is primarily used for Ergonomic Component Positioning. Its specific applications include:
Battery Shop Operations: Transporting and elevating heavy aircraft batteries to charging rack heights.
Brake and Wheel Changes: Aligning heavy wheel assemblies with the axle during tire changes on mid-sized airframes.
Avionics Tray Loading: Supporting heavy flight-deck displays or weather radar units during rack integration.
Why Choose SLT-660F?
Choosing the JET SLT-660F ensures that your shop equipment meets the industrial standards required for a Part 145 repair station. The precision-controlled lowering valve is a critical safety feature; unlike lower-quality tables that may "drop" the load, the JET valve allows for a metered, hydrostatic descent, ensuring that expensive avionics or machined parts are not subjected to impact loads.
The SLT-660F operates via a planar four-bar linkage system configured in a "scissor" geometry. The mechanical advantage is provided by a single-acting hydraulic ram that applies force to the inner linkage members. As the ram extends, the angle of the scissor members relative to the horizontal plane increases, converting fluid pressure into vertical linear motion. The stability of the platform is governed by the geometric stiffness of the welded steel members and the precision of the pivot pins. Under load, the system must resist lateral deflection (sway); JET achieves this through tight-tolerance machining of the pivot bushings and high-tensile steel construction, ensuring the table remains level even when the center of gravity (CG) of the load is slightly offset.
Note: This is heavy-duty industrial lifting equipment. Never exceed the 660 lb. rated capacity. Ensure the load is centered on the table to prevent tipping. When the table is in an elevated position, do not move the unit unless the floor is perfectly level and clear of debris. Installation of the handle and initial hydraulic bleeding must be performed by qualified personnel.
