lEconomical and long-lasting

H-Beam, an engineered timber

component is the core of the system.

Manufactured under stringent quality

measures, the wooden flanges are made

of chemically treated, seasoned timber.

Using a unique finger jointing method,

the webs are manufactured by joining

these flanges with boiling water-proof

plywood.

H-beams consume less timber, as low as

40% of the required timber volume.

Hence, they are light, dimensionally

stable and retain their structural

properties over a period of time, even

after continual usage. They are more

predictable, easy to design and use.

H-beams can be used and reused nearly

100 times, which is 8 times greater than

conventional timber.

H-beams are available in two sizes

namely H-16 (16 cms depth) and H-20

(20 cms depth). The length varies

between 1m to 4.00m for H-16 and upto

4.80m for H-20.

A suitable and more convenient type of

formwork for laying RC floors, the L&T

Flex System is made up of components that

give a firm support to floorings. It is suitable

for RC floors as high as 5.80 m and is very

well adapted for use with the Beam Forming

System.

H-beams positioned at designed intervals

provide additional support to the

plywood sheathing. These H-beams,

supported by telescopic props

mounted on tripods, ensure lateral

stability.

Props of various sizes – CT-250, CT - 300,

CT - 340, CT - 410 & EUREX 550 - can be

effortlessly mounted on the tripods, enabling

faster and easier erection of the shuttering

system. Height adjustments are done by

adjusting the prop nuts. Required dimension

is obtained through side-lapping of H-beams

in either the primary or secondary layer.

By facilitating re-propping, the system

minimizes the quantity of formworks

significantly.

Widely used in making large scale flat

slabs in construction majors like IT

parks, commercial complexes and

malls, L&T Flex Table System is handy

and easy to use. It is highly suited for

laying RC-floors up to 5.80m height.

Depending on grid sizes, standard

tables are made using suitable and

effective components: timber beam,

steel member, aluminum member,

collapsible props and plywood

sheathing. These primary and

secondary beam components are

connected firmly with table heads,

making the entire system rigid and

robust. Horizontal shifting of the system is

done using hydraulically operated pallet

trucks, while vertical shifting is done

using cranes. This avoids dismantling

of individual components, hence

reducing labour and cycle time.

L&T Beam Forming Support System

(BFS) is suitable for RC-Beams of depth

between 30 cm to 110 cm. It is

customised for use along with Flex and

Heavy Duty Tower systems.

Beam Bottom: Rigid H-20 beams /

H-16 beams, positioned at designed

spacing, support the plywood sheathing

and form the secondary layer. These in

turn are supported, for extra-stability,

by a primary layer of H-beams.

Beam Sides: Like the Beam bottom,

the Beam sides are also made up of

plywood sheathing supported by

H-Beams at designed spacing, running

along the length of the RC-beam.

Supported by the BFS, the H-beams are

clamped onto the H-20 beams provided

for the Beam bottom. The beam forming

support ensures the right angle between

the beam bottom and sides.

BFS extensions available in three sizes -

600mm, 800mm and 1100mm in length

- provide required adjustments in depth.

Salient Features

L&T Wall & Column Formwork

System is suitable for casting RC-walls

and columns of minimum 15 x 15 cm.

In both cases, the plywood sheathing is

supported by H-beams, backed by steel

walers. This assembly facilitates fixing

working platforms for access, checking

of reinforcement, concreting, etc.

Panels have extra provision to achieve

verticality and the concrete pressure is

sustained by high strength tie system.

The high strength tie system can be

through tie system or lost anchor

system depending on the structure. The

H-Beams can be butt and splice jointed

to form larger size of panels.

The entire panel, along with the

platform and alignment system can be

shifted using cranes as a single unit.

Panels are created in workshops at the

site and the assembly of components is

reduced, enhancing accuracy

throughout. Since the entire unit is

handled as a whole, loss of smaller

component is reduced, and contributes

to material productivity. In the absence

of a crane the panels can be dismantled

and handled manually.

The walers are available in sizes of

0.8m, 1.2m, 1.6m, 1.8m, 2m and 2.4m

for making panels and combination of

panels with splices and adjustments can

be made to arrive at the exact lengths of

RC wall.

0.3 manhours per cu.m for 1525 x 1525 towers

0.2 manhours per cu.m for 1525 x 2250 towers

L&T Heavy Duty Tower System is

widely used as staging for heavy floors

at higher altitudes, and also serves as

scaffolds on certain occasions. Heavy

duty frames are braced using standard

bracings, forming the heavy duty tower

system. Couplers and pins connect

frames together, ensuring verticality.

Spindles provided at the bottom can be

used to adjust height and level. At every

6m interval, the towers are braced with

permanent structures that prevent the

tower from twisting under abnormal

loading conditions.

Each heavy duty tower has an

unmatched capacity of 25 MT and is

ideal for handling heavy loads at

unusual heights. It also serves as Table

Formwork in multi-storied

constructions and can be handled as

single units up to a height of 10m.

The Heavy Duty Basic frames are

available in heights of 0.9m, 1.2 m or

1.8m. The Heavy Duty Towers are

available in two sizes namely

1525x1525 mm or 1525x2250 mm (in

plan).

Heavy duty towers can also be used as

scaffolding for application like external

finishing works, painting, cladding etc.

Salient Features

lHigh load carrying capacity of 6.25 MT per leg

lRigid and stable with minimum bracings

lEasy to erect and dismantle using unskilled labour

lEasily shifted using cranes and transport devices

lIdeal for heavy floors involving greater heights

lCan be converted into stair-tower withadditional standard components

lTowers are available in plan sizes of1525x1525 mm and 2250x1525 mm

L&T CLIMBINGSYSTEM

L&T Climbing System is used for tall

structures like cooling towers, tankages,

core walls, where staging or scaffolding

along the interior or exterior walls

would prove uneconomical.

In the Climbing System, brackets are

hooked to lost anchors, which are

already provided along the cast wall.

Entire shuttering is supported on the

climbing brackets. The brackets are

suitably braced to prevent any sway and

are provided with walkways, working

platforms and handrail for safety and

ease of operation.

Varying degrees of sophistication are

available in the climbing systems, a few

of which are listed below:

CB - 150 A: Simple climbing, crane

handled - platform width 1.50 m. The

brackets and wall formwork are to be

handled separately. Provision for

extension of bracket width is also

possible.

CB - 150 F: Travel climbing, crane

handled - platform width 1.50 m.

Roll back arrangement for de-shuttering

and cleaning of shutters. The wall

formwork and climbing bracket are

lifted as one unit. Provision for

extension of bracket width is

also possible.SUSPENDED PLATFORM 150A HANDRAIL POST

Automatic Climbing Formwork: The wall

formwork along with the climbing brackets

slide along the wall using hydraulics, thus

eliminating the need for a crane. This system is

very often used for core walls in high rise

structures, cable stayed bridge pylons, natural

L&T ACCESSSCAFFOLD SYSTEM

LABOUR PRODUCTIVITY FOR SCAFFOLDINGl0.15 manhours per cu.m

L&T Access Scaffold System provides

a free and safe working environment,

increasing productivity. It contains

frames, 1.8m high, braced with

standard H225 & 2H225 bracings that

form the main structure. Suitable

couplers and pins connect individual

frames with each other, giving the

tower the desired height. The towers

are provided with tower spindles at the

bottom for fine adjustments in height

and leveling.

The towers provide a continuous

corridor for working with the bracings

serving as hand rails. There are no cross

members or diagonal bracings that

impede free passage or safe working.

This is an ideal system for scaffolding

for heights up to 40m. The width of the

working platform is 1m. The scaffold

has to be braced with the permanent

structure at every 4m in height. Salient Features

lEconomical design

lLightweight, easy to erect or dismantleusing unskilled labour
