Schweiss Hydraulic Doors can now be opened or closed during an unexpected power outage with a DC battery-motorized back-up control system. Hangar owners/operators simply press “Up,” and their hydraulic door opens. The back-up systems are also engineered with a drill-driven backup system at no additional cost, which uses a screw gun 7/16” socket hex head. Hydraulic tractor fittings come standard with each Schweiss Red Power pump hydraulic unit.
Emergency door lowering can also be as simple as turning a screw on the pump. A large moving door can close at a controlled, safe speed, no matter the situation or emergency. It’s that easy… no mess, no oil drains back into the tank.
Schweiss Doors has been at the forefront of providing hydraulic and liftstrap bifold doors for aviation and agricultural uses throughout the U.S. and Canada.
The Schweiss hydraulic door pump unit provides faster door speed when opening and closing, giving a cycle time of approximately 30 seconds. It is the most efficient pump on the market.
Hangar owners/operators do not want a slow door that lets the heat out of their hangar in the winter or air conditioning out in the summer. The uniquely designed Schweiss pump unit is a all-in-one contained unit and can be top-hung or under-hung and mounted on the hangar wall, floor, beneath a bench or in a back room.
The hydraulic pump system uses a fast and quiet, fan-cooled LEESON 1,800 rpm motor available in 2 to 10 hp, depending on the size and weight of the door. Schweiss doesn’t use undersized motors that can get hot and burn out.
Two powerful cylinders carry the entire weight of the door. Schweiss cylinders won’t bend, break or bow. Another important feature that hangar owners/operators won’t find on other hydraulic doors is the recent introduction of “spherical bearings.” These bearings are located between the teardrop area and cylinder plate at each end of the doors’ cylinders — a perfect answer to a safer, stronger and longer-lasting door.
The frames on Schweiss hydraulic doors have “added-strength” with double end hinges and more hinges per door, which means they don’t have to support as much weight per hinge.
