Aggregate Housings

Power pack housings – the load-bearing structure of the hydraulic unit

Power pack housings form the load-bearing frame in which the electric motor, hydraulic pump and oil reservoir are combined into a compact functional unit. They accommodate mounting bores, connection flanges and internal supports, transferring all vibrations cleanly into the vehicle frame. At SULEJ Ladebordwand you will find power pack housings in steel and aluminium versions, matched to the installed component and suitable for common power pack configurations on the market – a solid base for the hydraulic drive of your tail lift.

Load-bearing role and connection layout – more than just a shell

Unlike pure covers, the power pack housing takes on a structural task: it fixes motor and pump in the intended axial position, seals the oil chamber against contamination and provides defined mounting points for valve blocks, pressure lines and return connections. Steel housings are usually deep-drawn and powder-coated, while aluminium housings are produced as die castings or profile constructions. Internal ribs, vibration dampers and sealing surfaces ensure that pump drive vibrations are not transferred to the bodywork and that the oil system remains cleanly enclosed.

What matters when replacing the housing

When replacing a power pack housing, the alignment of the mounting patterns, the position of the pressure and suction connection ports as well as the depth of the oil chamber are decisive. Pay attention to the condition of the internal sealing surfaces, to cracks around the motor flanges and to corrosion traces around the threaded bores. A distorted housing leads to leaks at the pump flange – here a precise replacement of the entire load-bearing structure is more effective than repeatedly retightening the bolts.

Benefits at a glance

• Load-bearing structure for motor, pump and oil reservoir from a single body
• Steel and aluminium versions for different weight and load classes
• Sealed separation between the oil chamber and the outside environment
• Compatible with common connection patterns for pump, valve block and high-pressure lines

A precisely fitting power pack housing is the prerequisite for a quiet, sealed and long-lasting hydraulic drive on your tail lift.
