The EH100 compact monorail air hoists consists of two trolleys with a load capacity of 50 tonne each.
Centralised Pneumatic Control for four EH50 Hoists
On a BOP Handling System, consisting of four JDN EH50 Monorail Air Hoists, the control system had to fulfill the following requirements:
- Independent control of individual hoists
- Control of two hoists as a pair
- Common control of all four hoists
- Optional individual pendant control for maintenance operations
Each monorail air hoist is equipped with an emergency lowering device that allows a controlled lowering of the load in case of interruption of the air supply. This is an example of JDN being able to meet complex requirements for the pneumatic controlling of a multiple hoist installation.
