Automated conveyor technology for stacker cranes in high rise storage facilities and small parts warehouses

Horizontal application in the field of conveyor technology:

Problem:
Stacker cranes in high rise storage facilities move along rails at very high speeds. Before reaching the end points of the aisle, they are brought to a standstill via an electrical braking system. Should the electrical control of the conveyor technology fail, the stacker crane travels unbraked into the end stop. Severe damage to the equipment, building, or personnel is the result.

Solution:
A COMPENSER® from the DC series acting in both directions of travel, or a single-acting COMPENSER® from the C series or CE series, is installed on the stacker crane as end-position damping at the end stops. In an emergency, the stacker crane is braked by the shock absorbers with the maximum permissible deceleration or reaction force.

Advantage:
No damage to the stacker crane, building, or personnel in an emergency situation.

Operational load cycles of the stacker crane:

In fully automated high rise storage facilities, great importance is placed on efficiency. To achieve maximum usable storage space, reaching the ends of the aisles is required. This leads to permanent approaching and depressing of the shock absorber’s piston rod at the end point. The industrial shock absorbers from LEBEN-Dämpfungstechnik GmbH are market leaders for cyclic loads, as they are equipped with particularly reliable and durable technology. To achieve several 100,000 cycles without interference, sensor monitoring is provided and an external accumulator is usually installed on the buffer.

Vertical application in the field of conveyor technology:

Problem:
Stacker cranes lift heavy loads as pallet lifters, telescopic lifters, or via a lifting hoist. Mechanical damage and errors in the electronic control system can lead to an unbraked fall of the lifting equipment. Severe damage to the equipment, building, or personnel is the result.

Solution:
A single-acting COMPENSER® from the C series or CE series is mounted on the stacker crane as a fall protection device. Alternatively, a single-acting COMPENSER® from the C or CE series is firmly anchored to the floor plate of the building as an emergency stop. In an emergency, the falling mass is cushioned by the vertical buffers with the maximum permissible deceleration or reaction force.

Advantage:
Industrial shock absorbers for conveyor technology prevent damage to the warehouse technology, the building, or personnel in an emergency situation.
