All JHT - Janssen Hydraulik Technik GmbH cranes are equipped with a double-acting hydraulic pump, i.e. the support arm is moved upwards with each pump stroke (time saving). Depending on the model, a maximum load of 500 to 2000 kg is possible. In addition, all wheels have foot protection (employee protection). The workshop cranes have either a spread chassis (collapsible, space-saving) or a parallel chassis (bypassing pallets).
