Lifting and crane equipment
construction) is designed for lifting two people, building materials and
tools directly to the workplace to carry out painting and decorating
the outside of buildings and structures up to 150 meters.
construction on the buildings of the cradle with a flat roof using the
console. One - for single facade
lift, two - for a double. The scope of delivery
facade lift may include the console, providing cradle flight distance
0,9 m 1,5 m 2,5 m from the walls of the building that provides the
performance of work both on flat vertical surfaces, and on projecting
corners of buildings or structures.
Building maintenance units
are equipped with:
- consoles on the roof of
the building for the suspension of construction cradles;
- two catcher insurance;
- portable remote
- rope, cable.
Can also be supplied
separately winches LEF-500 (electric friction, r / n 500 kg, lifting
height up to 150m), the consoles with the emission of 0,75, 1,5, 2,5 m
from the building and other spare parts. At the request of the
customer's building cradle is equipped with reinforced concrete
counterweight weighing 50 kg or metal weighing 20 kg, iron load differs
from the convenience of installation of concrete, due to the small
weight and long lifespan.

Device facade lifts
consists of a
frame, lifting machinery, catches and electrical equipment. Skeleton of
structure made of pipes and corners at the ends of its established
mechanisms of catches and guide rollers of lifting and safety ropes.
Under the deck working
platform having a fence, mounted lifting mechanism, which is a
double-drum winch. In leading drum winch
built a three-gear drive, details of which operate in a closed oil bath.
Friction winch mechanism
for lifting pulls no lifting ropes on the drum, and moves on them due to
friction. This cradle can be raised
to any height, determined by the length of rope.
Tilt mechanism is
equipped with two automatic brakes - disc and drum brakes. Disc -
is built into the leading drum winch, operates in case of excess load
moment. Drum brakes - automatic
stop, installed on the drive shaft of the planetary gear, a
spring closes when you turn off the current in the control circuit.
suspended on two lifts and two safety ropes, the upper ends of which are
fixed on the consoles installed on the roof of the building. The lower ends of the ropes, weights inventory.
When breakage or
weakening of the ropes included automatically interlocked with catcher,
and the cradle hangs on the safety line. Electrical control
circuit with opens.
In the control circuit
switches are the extreme top and bottom of the cradle. In the event of a
outage cradle is equipped with a hand-driven winch.
Within the construction
site construction cradle moves on wheels, mounted on the frame. From
object to object
without disassembling it shipped by truck.
Environment, which can be
operated lift facade:
are satisfied by the facade lifts:
- temperature of -40 to
+40 ° C;
- the upper value of
relative humidity at 25 ° C of the atmospheric type II according to GOST
15150 - 80%;
- wind area installation
GOST 1451 - IV;
- wind speed at 10 m, not
more than 14 m / s;
- explosion - an
- fire hazard - fire
- building cradle should
be done in the form of a skeleton with a platform to accommodate the
worker (workers). Floor area per person
cradles must be at least 0,7 m2. Paul bassinet should not
- one should be suspended
cradle hung on a hoisting cable and have a safety line;
- two to be suspended
cradle suspended on two ropes, and have two safety rope;
- load one hanging
cradles must be not less than 120 kg, two suspended - not less than 300
- construction cradles
around the perimeter should be protected. The height of the fence
with a non-working party should not be less than 1200 mm, and from the
front of work - not less than 1000 mm. Device cradle doors in
the fence is not permitted;
- barriers should be
designed for a load of not less than 1300 N for attaching carabiners
safety belts and tethers for working tool;
- construction should be
suspended from the cradle to the console, installed on top of the
building (construction). Coefficient of stability
freely arranged consoles should be not less than 2,2;
- sustainability of
building cradles at work and with the relocation should be checked by
calculation. In order to prevent
buildup cradles, they can be fitted to support the construction;
- building the cradle
must be fitted with rollers to move along the ground.
