What Is a Cross Staff Used For?
A cross staff is one of the simplest surveying instruments for laying out right angles on the ground. Because its two lines of sight are at right angles, a surveyor who lines up one pair of sights with the chain line can look through the other pair to fix a point square to it — the basis of perpendicular offsets in chain surveying. It is used in surveying practicals at civil engineering colleges, polytechnics and ITI surveyor courses, and for outdoor work on right angles and perpendicular lines in school maths labs.
What to Specify When Ordering
- Quantity — for example one cross staff for each survey group in a practical class.
- Other survey items — ranging rods, measuring chains and optical squares are separate items that can be quoted on the same enquiry.
- Delivery destination and any tender reference.
Frequently Asked Questions
What is a cross staff used for?
For setting out right angles and taking perpendicular offsets from a survey line in chain surveying, and for practical work on right angles in maths labs.
What is an open cross staff?
It is the type with metal arms carrying two pairs of vertical sights fixed at right angles, as on this model. The French cross staff and the adjustable cross staff are other common types.
What is the head made of?
Gun metal, brass or another alloy that does not rust. The head sits on a wooden pole of size 4 in x 4 in.
How does a cross staff differ from an optical square?
This cross staff sets out right angles with open vertical sights on a metal head mounted on a wooden pole. JLab’s Optical Squares is a hand-held instrument that lays off right angles with two optical glass pentaprisms in a sturdy housing.
What information is needed for an export quotation?
The quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if there is one.
Who manufactures the Cross Staff Metal?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of surveying, maths lab and educational laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The cross staff is built in JLab’s own works, not bought in from a trader, so colleges, schools, dealers and importers buy it factory-direct and repeat orders come from the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Myanmar in Southeast Asia, Mongolia in East Asia, Canada in North America, Namibia in Southern Africa and Cameroon in Central Africa. For institutional tenders, see the JLab lab tenders page.
