We are pleased to introduce our first product: a simplified elevator for transporting goods between two floors within a commercial enterprise. It has been operational since the beginning of 2012 and has proven itself in daily business operations.
Location of our hydraulic goods lift
The hydraulic goods lift by SeaLeRo GmbH & Co. KG, formerly known as H. Lohmann Schiffs- und Industriebedarf e. K., facilitates the transportation of goods in the newly built warehouse at the company headquarters in Haren (Ems). Since the foundation was laid in 1985, the trading company has not only made a name for itself in the shipper city of Haren but also regionally, by reliably fulfilling customer-specific procurement requests. The company now also has additional offices in Rotterdam and Münster.
Technical details
General construction and function
Our hydraulic lift is designed as an indirectly driven lift: The platform is not moved directly by the hydraulic cylinders, but indirectly via a pulley system. This system consists of four wire ropes, connected to both the lifting platform and the guide frame, redirected over pulleys. The upward and downward movement of the platform occurs by the hydraulic cylinders acting directly on the pulleys.
Powerful yet quiet
The power required for operation is generated by a 4 kW submersible motor unit. Thanks to its simple construction and the electric motor running quietly in hydraulic oil, our elevator offers a pleasantly low noise level

Spacious platform for large loads
The platform has a base area of about 2.5 square meters, providing ample space for larger loads – for comparison: A Euro pallet has a base area of about one square meter.
This size makes our column lift particularly suitable for applications with bulky goods.
Intuitive Control
The goods lift is operated using a programmable logic controller (PLC). The user interface is a surface-mounted control unit with three buttons and an emergency stop switch. The current position of the platform is indicated by the continuous illumination of the corresponding button, while movement is signaled by the flashing of the respective button. Even with the elevator shaft closed, one remains constantly informed about the platform's location.
In the event of a malfunction, the display in the main switch cabinet provides initial valuable information for troubleshooting. Clear hints in the form of keywords like 'Emergency stop' or 'Overload' facilitate the investigation of causes and allow for quick resumption of operations.
Comprehensive safety measures
To eliminate the risk posed by the lifting motion, our simplified goods lift is housed within a closed shaft and may only be operated by specially trained personnel. To prevent unauthorized access to the hazardous area, the access doors of the elevator shaft are electromechanically locked. The doors can only be opened when the platform is at the designated floor or in an emergency using a special key.
Furthermore, the goods lift includes the standard safety features of hydraulic lifts. These include line rupture valves, a pressure switch, and a pressure relief valve. For regular inspection of these safety devices, the hydraulic unit is equipped with a bypass that allows simulation of a hose break in the drive train.
Despite these extensive safety features, the transportation of people is not intended with this elevator configuration. The goods lift is exclusively designed for transporting goods and should be used accordingly to avoid safety risks.
Good reasons for our freight elevator
The decision to opt for our freight elevator was made primarily due to its favorable cost-benefit ratio. Alternatively, the purchase of a forklift could have been considered.
However, a simplified goods lift offers several advantages compared to large forklifts:
- lower maintenance costs,
- less space required,
- simple operation,
- no risk of damage from bumping into gates, doors, shelves, etc.
Overall, our freight elevator is a safe and economical solution for efficient goods transport between different levels.
