When STEELBRO notifies you that a modification is required, it is the responsibility of the Owner to ensure that the modification is carried out in accordance with the instructions from STEELBRO and if requested, to withdraw the Sidelifter/trailer from service until the modification has been carried out.
The Owner should withdraw the Sidelifter/trailer from use when any deficiencies are identified during inspection of the Sidelifter/trailer which may affect its safe operation, until the design or operational deficiency is rectified.
The Owner should ensure that neither the Sidelifter/trailer nor any of its components are used beyond their design capacity. For crane design capacity refer to the Working Load Limit decal and for the chassis design capacity (when applicable) refer to the Chassis Plate decal. Copies of both of these are included in the manual.
Particular care should be taken to ensure that the emergency stop controls are always operational.
