Laser Accurate Angles

KwikMark - Mining Equipment in South Africa

KWIK-ANGLE is an intrinsically safe, versatile and compact instrument used for measuring vertical and horizontal angles and is also indispensable when extending line and grade in routine mining and tunnelling operations. Specific uses are, straight line extensions and turn off angles in tunnels, raises, winzes, ore passes and setting of grades. Turn off angles in room and pillar mining and setting of fan holes to be drilled in sub level stoping.

This extremely robust but lightweight unit is made from hard anodized aluminium. The laser pointer is powered by a 3 volt internal battery – providing an operating time of 10 hours. It is easily fitted to a standard surveyor’s tripod and incorporates a tribrach levelling base with a bullseye bubble, a pan head and an extension shaft.

The laser pointer produces a bright green spot, visible to a distance of over 100m and can be rotated 360° in the horizontal and 180° in the vertical axis.

The horizontal protractor and vertical inclinometer measures angles to an accuracy of .01 degree.

The instrument consists of:

Pan Head

The pan head has two bearings, both can be locked or unlocked by means of screws. The one bearing provides 360° rotation on the horizontal axis and the other provides 180° on the vertical axis. (0 to 90 degrees left and right sides).

Extension Shaft

The pan head is attached to the levelling base by means of an extension shaft allowing it to raise to 100mm. A lock-screw is provided to lock the extension shaft in the lowest position or any other position up to 100mm.

Leveling Base

This base is a surveyor’s tribrach and has a 5/8 wit worth thread to fit onto any standard surveyors tripod and is used to simplify the levelling of the instrument.

Digital Inclinometer

A digital inclinometer is fixed to the side of the pan head where angles from horizontal to vertical angles can be measured.

Laser Pointer

The top of the pan head has a laser pointer which rotates 360° on a protractor enabling horizontal angles to be measured with an accuracy of .01°. The moveable protractor allows the miner to ZERO the protractor


The type of the laser is a class IIIa and has an effective range of 100+ meters.

Battery Pack

It is powered by an internal 3.0 volt battery.

Different uses for KWIK-ANGLE unit

Mining and Tunneling
  • Straight Line Extensions: Kwik-Angle can be set up below a survey bench mark and laser light can shine on a line suspended from a second survey bench mark and on rock face simultaneously creating a straight line for 100 meters.
  • Turnoff Angles: Kwik-Angle can establish a straight line as described above and at desired turnoff point can be re-aligned, back sighted to survey bench mark and then turnoff desired angle.
  • Grades: Kwik-Angle can be set up under survey grades and by means of fine adjustment of extension shaft the laser light can light up the grade lines thus establishing grade for up to 100 meters.
  • Box Holes: Horizontal angles are turned off as in (2) above and then by means of the inclinometer a vertical angle is also measured.
Construction Underground
  • Conveyor Installations: Aligning and Grading
  • Foundation Work: Aligning and leveling of foundations
  • Pipe, Cable and Track Installations: Aligning and Levelling

Other Uses Indicating vertical and horizontal lines:
  • Painted on aeroplanes, boats and squash courts etc.
  • Mirror & cupboard installations
  • Tiling on walls and floors
