The Tremix Surface Vibrator SMEH/SMPH is used for working bay widths from 6 to 12 m. The depth effect is 100 to 150 mm depending on theconcrete consistency and the length of the beam. Thicker concrete slabs should be vibrated with a Tremix Poker Vibrator before levelling. The screed consists of two main parts: Tremix beam S 150 and Tremix electric vibrator unit ME150 or Tremix vibrator unit MP for petrol drive. The beam S150 consists of two Tremix light alloy profiles height 150 mm. The 8.0 m beam may also be delivered in sections for ease of transport. The beam is strenghtened with cross stays. Beam lengths over 8 m are delivered in two sections. The switch with reversing mechanism is mounted on a separate clamp fixed to one end of the beam. Tremix offers various accessories such as Tremix outriggers, used when the surface vibrator is run on elevated track rails and skates to be used directly on the reinforcement. The skates can be adjusted in several heights. Standard beam lengths: 6.2, 7.2, 8.0, 8.4, 9.4, 10.4, 11.4 and 12 m.
