Tronair 8721A – Malabar 11-Ton Tripod Jack, Air Pump

The Malabar 8721A is a 11-Ton (22,000 lb) hydraulic aircraft tripod jack engineered to lift aircraft from the forward fuselage or main wing jacking points during maintenance, inspections, and ground operations. The single-stage hydraulic design provides controlled lift and positive lock at any extension height. A factory-installed air pump allows rapid initial extension without additional equipment. CE-marked for compliance with European aviation safety standards. OEM-specified for Embraer ERJ-170, ERJ-175, ERJ-190 and others. Also approved for Airbus A319, A320 and others.

Safety Features

• Ram Lock Nut: Prevents the lowering of the ram. The ram lock nut must be lowered as the aircraft is being lifted. Ram lock nuts must be kept within 2" of the stop while raising the aircraft.
• Hold-to-Run Air Valve: Requires the operator to hold the air valve lever to raise the ram using the air pump. Releasing the air valve lever stops the upward movement of the ram.
• Lock Nut Retention Ring: Prevents the lock nut from being unscrewed from the second stage.
• Pressure Relief Valve: Prevents overload during raising operations.
