Kwikangle
Laser Accurate Angles
KWIKANGLE is a versatile instrument used for measuring vertical and horizontal angles plus any leveling likely to be found in the daily routine of underground mining and tunneling. Kwikangle is best described as a simple theodolite which has an accuracy of 1 degree, however the telescope has been replaced with a laser pointer. Vertical angles are measured by means of a built in inclinometer.
This unit is compact and fits onto any standard survey tripod. The mass of the unit is 3 kg and the body is made from nickle plated brass. The laser pointer is powered by a 4 volt rechargeable battery pack which provides an operating time of 18 hours. The range of the laser pointer is 100m in underground conditions.
Typical uses for the KWIKANGLE 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.
The Instrument Consists Of:
Leveling Base
This base has a 5/8' witworth thread to fit onto any standard surveyors tripod. The base is also equipped with a bullseye bubble and three leveling screws.
Pan Head
The pan head has two bearings both of which can be locked or unlocked by means of screws. The one bearing provides 360 degrees rotation on the horizontal axis and the other provides 180 degrees on the vertical axis. (0 to 90 degrees left and right sides).
Extension Shaft
The pan head is attached to the leveling base by means of an extension shaft which allows the pan head to be raised 100mm. A lock-screw is provided to lock the extension shaft in lowest position or any position up to 100mm.
Inclinometer
An inclinometer is fixed to the side of pan head and angles from horizontal to vertical can be measured with an accuracy of one degree.
Laser Pointer
The top of the pan head is equipped with a laser pointer which rotates 360 degrees. The laser pointer rotates on a protractor which enables horizontal angles to be measured with an accuracy of one degree. The protractor is also movable which allows the user to zero the protractor.
Laser
The laser is a 3,5mw class llla type battery powered laser and has an effective range of 100 meters.
Battery Pack
4 volt rechargeable battery pack is used. Batteries permit constant use for 18 hours between charges.
Different Uses for KWIKANGLE UNIT
1. Mining and Tunneling
- Straight Line Extensions: Kwikangle 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 100meters.
- Turn - off Angles: Kwikangle can estabilish a straight line as described above and at desired turn - off point can be re-aligned, back sighted to survey bench mark and then turn-off desired angle with an accuracy of one degree.
- Grades: Kwikangle 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 estabilishing 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.
2. Construction Underground
- Conveyor Installations: Aligning and Grading
- Foundation Work: Aligning and leveling of foundations
- Pipe, Cable and Track Installations: Aligning and Levelling
3. Other Uses Indicating vertical and horizontal lines:-
- Painted on aeroplanes, boats and squash courts etc.
- Mirror & cupboard installations
- Tiling on walls and floors
