Spencer stretchers are also distinguished by their MBC backrest mechanical regulation system, a real milestone in the technique of blocking systems. A system that guarantees trustworthiness and durability for millions of manoeuvres without having to use any kind of lever and above all allows raising of the backrest even laterally. To reset the level or select intermediate positions you use just one hand to activate the ergonomic handle, placed in a distal position, easily found and at the same time, sustaining the weight.

A clever and unprecedented mechanical system, that interacts with a rack made from the top of the patient surface mould. It assures the use of the anti-shock system in one swift movement, without the need to use compound levers. To reset the level or select intermediate positions you must modify the position of an easily identified lateral lever.

• Position of the head inclination between 0 and 75 °
• Position of the anti-shock and Trendelenburg positions between 0 and 10 °
• Position of the comfort or Fowler position between 0 and 45 °

This mechanism permits the adaptation of the stretcher to the needs of the rescue operation. In order to make getting on and off easier in the case of walking patients or for the elderly, it is sufficient to put the Cross into the inclined position. When transferring the patient there is the possibility to adjust the stretcher into an intermediate height, modifying at the same time the inclination of the posterior legs, therefore ensuring that the operators do not strain any muscles in transferring the patient from the bed to the stretcher or vice versa.

The variation of the height of the trolley in relation to the different loading levels of the ambulance is possible thanks to:

• a loading trolley with six different heights, extremely easy to adjust without requiring specialised technicians
• a patented system of geometrically variable runners, that guarantee an optimum sliding angle during loading and also maintaining level once the ambulance

In areas where the patient assistance becomes critical both in therapeutic terms and in transfer terms, the frame has been modelled to consent more comfortable and effective operation.

If necessary the Cross can be shortened to guarantee good manageability in limited spaces or small lifts. The trolley system at the front can rotate upwards (automatic blocking system), acting hence as a bumper to protect the patient from bumps when the stretcher hits a wall, or moves downwards.

Each time the stretcher is put into the ambulance or on the ground the wheels rest in a space in the frame, thanks to an elementary mechanism: another way of avoiding strain.

An excellent distribution of the weight, guaranteed by an advanced geometry and welded chassis, which gives the Cross absolute stability.
