Camlok BTG Concrete Pipe Lifting Clamp Set, 1500-3000 kg

Lifting concrete pipe vertically with a three-clamp set and chain sling

The Camlok BTG is concrete pipe lifting gear for the vertical transport of concrete pipe sections and manhole pipes. It is sold as a set of three clamps that comes complete with a 3-legged chain sling, and the working load limits in the datasheet apply to the full set of three. Camlok gives a pipe diameter of up to 2000 mm and states the gear is for concrete pipes according to DIN 4034.

The attraction on site is simple handling: the clamps go onto the pipe wall and come off again with a lever, and the product page notes that the gear lets the trench for a manhole pipe be kept small and helps place pipes accurately on top of one another. Two sizes are listed, BTG1500/3 and BTG3000/3.

Sets, wall thickness and chain size

The jaw capacity is the wall thickness the clamp can bite: 40 to 120 mm on the BTG1500/3 and 50 to 180 mm on the BTG3000/3, so check the pipe wall thickness at the lifting point first. The two sets differ in everything: mouth depth 165 against 245 mm, pressure line 100 against 175 mm, chain 6 against 10 mm and set weight 34 against 60 kg. The datasheet weight is per three-legged lifting gear, not per clamp.

The 3 in the code is the three clamps and the 3-leg sling; it is not a size. Sets are priced and supplied as a unit, so specify the pipe diameter, wall thickness and the weight of the heaviest pipe when asking for a quotation. The manual says never to pick up loads below the minimum marked on the clamp, so a set rated 3000 kg should not be used for light pipes.

Fitting the three clamps and lifting

Check the pipe surface for grease, standing water, oil, scale or coatings and confirm the sling is slack. To close a clamp, press the lever down; set the three clamps on the pipe wall and make sure all three are properly seated before the weight comes on. Look for obstacles in the path and for twists in the chain sling.

Lift smoothly with the sling vertical, never with an endless or four-leg sling, and keep everyone out of the area under and around the pipe while carrying it close to the ground. To release, lower until the attachment is load-free and the suspension eye moves freely, then move the lever to Open and remove the gear. Manual checks cover smooth operation, weld cracks, shell plate distortion, teeth cleaning, lubrication, fasteners, jaw bolt and locator pin, and jaw wear, in daily, weekly and monthly columns.

Pipeline, drainage and precast jobs

BTG sets are used where concrete manhole and drainage pipe are laid in trenches, and in precast yards and at stockpiles where pipes are loaded out vertically. Water and sewerage network works in the GCC use large concrete pipe, so a three-clamp set that makes positioning accurate saves excavation width. Confirm that the pipe is to DIN 4034 or the dimensions are within the wall thickness range before ordering, since pipes to other standards may differ.

Selection and installation notes

Lifting clamps and grabs must be selected from the working load limit, the thickness and size of the load and the lifting angle, and used only by trained people under the site lifting procedure. Check the working load limit and the range on the marking, inspect the clamp before each use, never exceed the rated load or the stated angle, keep people away from the load and follow the periodic examination rules of the country where it is used. Damaged or worn clamps are taken out of service.

Information needed for a quotation

Send the full model code, the quantity, the delivery location in Oman or the GCC, the intended use and any accessories needed, so that the complete package can be quoted together.

Documents and supply information

The manufacturer data sheet is attached to this page and should be read together with the project specification and the site risk assessment before a purchase is confirmed. Ratings, standards and dimensions are quoted as printed on that sheet. Lead time, stock position and certificates available with the shipment are confirmed in the quotation, and we supply to Oman and the wider GCC region for industrial, utility and building services projects.

The BTG set already includes its three-leg chain sling. Other items on the Camlok site for ground works include the CP pile pitching clamp. Rated slings, a crane hook with a safety latch and a spreader are lifting-plan items which are not part of the set. The catalogue lists the BTG under ground works, product group I4.

Frequently asked questions

What does the 3 in BTG1500/3 mean?

It marks the set of three clamps with a 3-legged chain sling; the working load limit applies to the three together.

What pipe diameter can be lifted?

Concrete pipe sections up to 2000 mm in diameter.

Which standard is mentioned?

The datasheet states the gear is for concrete pipes according to DIN 4034.

What wall thicknesses fit?

40 to 120 mm for the BTG1500/3 and 50 to 180 mm for the BTG3000/3.

How is the gear released from the pipe?

Lower until the attachment is load-free, then move the lever to the Open position, per the manual.
