Abstract: The invention relates to a support frame positioning a laser beam level and comprises: a first support module 1 inclusive a reference element 10 that can be positioned against a planar surface and enganging elements 11 located in a longitudinal direction A1 to cooperate with a second support module 2 displaceable relative to the first support module 1, bracing means 22 on the second support module 2 to support a laser beam type level 3 and a motor 25 to power a drive shaft in either of two directions of rotation of at least one element translatable along the first support module 1, and a remote control for said motor 25. The support frame may be positioned in height on walss and allows automatically positioning the laser beam in the continuous and progressive manner FIG. 1.

Abstract: A support frame for positioning a laser beam level includes a first support module having a reference element that can be positioned against a planar surface and elongated engaging elements that cooperate with a second support module that is displaceable relative to the first support module. A brace on the second support module supports a laser beam level. A motor drives a drive shaft of at least one element that is translatable along the first support module in both directions of rotation. The motor can be remotely controlled. The support frame can be positioned at different heights on walls and allows automatic positioning of the laser beam in a continuous and progressive manner.

Abstract: A modular laser level determination system includes a laser beam generator in a housing, fixed to a positioner. The laser beam is oriented towards a central shaft inside the housing that is not closed off by any obstacles and passes through a collimator. A rotation drive module of an optical assembly comprises at least one reflection plane. The rotation drive module extends in a direction coaxial with the center line of the laser beam. The rotation drive module comprises a brushless motor with electronic switching, a hollow shaft, and a stator fixed to an element fixed in rotation. The stator can be tilted by a module for determination and adjustment of the inclination with respect to a reference place. The laser beam generator is fixed to the brushless motor.
