In order to transport and handle easily, the suspended access equipment might be introduced in a form of unassembled parts from the manufacturing facility, after which will be assembled only while all additives arrive within the construction site.

Suspension platform

The suspension platform is a suspended closed frame device with the protection guards around, designed to carry the working team of workers, equipment and materials for paintings at heights.

The suspension platform is of steel or aluminium structure.

The suspension platform is consisted of 3 primary segments and two erection frames for hoists at each end. Where each segment is consisted of the balustrade at the the front and rear, in addition to the base. The the front balustrade (remaining to the running floor) is 0.9m high, the rear balustrade 1.2m high. The multiple primary segments and the erection frame for hoists at both ends form a closed body platform. The fundamental duration is 1m, 2m and a couple of.5m; the finished available length is 1m, 2.5m, 3m, 3.5m, 4m, 4.5m, 5m and so on. ZLP800 kind platform not more than 7.5m.

Suspension mechanism

The suspension mechanism is a device designed on the top of constructing to suspend the suspension platform by way of metal twine ropes. The suspension mechanism is consisted of two suspension brackets with identical structure, assembled in pairs.

The suspension bracket ZLP800 type suspended get right of entry to gadget is consisted of the front base, rear base, tommy bar, upper column, front beam, middle beam, rear beam, reinforced cord rope and counter weight. Where the middle beam is installed inside the front and rear beam; the distance between the front and rear base can be adjusted via changing the location of installation hole of connecting bolt, with an adjusting range 2~4m, adjusting space 0.2m. The front and rear beam is mounted at the front and rear base thru the tommy bar; the space from the beam to the ground can be adjusted by means of changing the position of installation hollow of connecting bolt among the tommy bar, the front and rear base, with an adjusting eight variety

1.Three~1.8m, adjusting space 0.1m, it’s miles an adjustable suspension bracket.

The groupware of the reinforced cord rope is attached with both ends of the front and rear beam thru the turnbuckle, coupling sleeve and the top column. The complete tension of the suspension bracket can be stepped forward with the aid of tightening the wire rope thru the turnbuckle.

Hoists

The suspended get entry to gadget is furnished two LTD8.0 hoists with power of one.8kw (ZLP800 type), that are mounted inside the erection frames of hoists at each end of the suspension platform. The hoist is the electricity facility to force the suspension platform to move up and down.

Hoist-frame

The raise motor is the 3-phase asynchronous motor with the electromagnetic brake, wherein the everyday close kind DC electromagnetic brake is mounted on the higher give up 9 of the primary shafts of the motor. When strength deliver is switched on, the armature iron releases from the friction plate under the movement of electromagnetic force, so one can guarantee the motor to run commonly; while strength deliver is switched off, the armature iron continues closed with the friction plate beneath the motion of spring pressure, on the way to break the motor right now; using the self-lock of motor can save you the suspension platform from falling down resulting from overload. The electromagnetic brake has a semi-circular launch device, the descending take care of is inserted into the discharge tool thru the kidney-form take care of hollow on the upper of the quilt of motor; whilst lifting the deal with upwardly, it can open the brake manually. The suspension platform can comprehend its guide fall beneath the pressure of self-gravity. At the joint of the shaft give up of motor and the input give up of the lowering mechanism in the box, the centrifugal reducing mechanism is established, that is used to save you the suspension platform from falling down sharply because of stall speed when it makes unfastened fall.

The reducing mechanism in the field is consisted of the bug wheel, worm tools and a pair of-elegance sub-velocity reducing transmission system of internal gears. The working wire rope shall encircle the dovetail groove on the outer give up of the inner gear disc in “α” form after getting into the body (See Figure 2). When the motor drives the internal tools disc to show with exclusive instructions, below the motion of the friction pressure formed between the wire rope and dovetail groove, the hoist and suspension platform will pass up and down along the cord rope.

Safety Lock

The suspended access gadget is provided two LSG20 protection locks, mounted respectively inside the bracket at the higher of the erection body for the hoists at both ends of the suspension platform.

LSG20(LSG30) safety lock is the skew-free protection lock; it is truly the tool to save you the ten-suspension platform from falling down by way of locking the safety twine rope automatically when the suspension platform tilts caused by the broken working wire rope or fall of 1 cease of the suspension platform.

The protection lock is best to clamp the rope automatically by means of the swing arm and cord locking mechanism; it’s far a kind of the normal close lock

When it works generally, the scroll wheel on the swing arm will carry the swing arm underneath the pressure of the running cord rope, so that it will then motive the rope-locking mechanism to unfasten, and make the safety lock under an unlocked situation. At this time, the safety wire rope can get entry to into the protection lock without difficulty. When the running wire rope breaks or the suspension platform tilts (at certain angle), the strain at the scroll wheel at the swing arm resulting from the operating wire rope will disappear, in order to make the swing arm fall to the authentic locking position, and purpose the rope-locking mechanism to take hold of and clamp the safety cord rope absolutely, and consequently the protection lock will comprehend the automatic lock on rope.

  • Unfasten the nets among the scroll wheel and connection plate
  • Increase or reduce the locking attitude of protection lock in line with the indicated course
  • Tighten the nuts between the scroll wheel and connection plate
  • Adjust the rope-locking perspective fashioned with the horizon to three°—8°

Working wire rope and protection wire rope

The operating wire rope could be used to droop and raise the suspension platform after coming into and encircling the hoists; it’s far truly the carrier of the suspension platform for motion. The safety wire rope will only play a position to save you the suspension platform from falling or tilting with the aid of being clamped by way of the protection lock whilst the working twine rope breaks or the suspended get entry to gadget turns into tilted, so one can then assure the working group of workers in secure.

The operating wire rope and protection cord rope are the primary additives to support the load of the suspended get right of entry to device, consequently, the twine rope in order to be used have to meet the given requirement. Preferably, the operating twine rope and the safety wire rope have to be the zinc-plated one (it must be, Φ9.1-four×31Fi+PP for ZLP800 kind) with functions of high energy and rust-proof capability.

The groupware of the reinforced cord rope is attached with both ends of the front and rear beam thru the turnbuckle, coupling sleeve and the top column. The complete tension of the suspension bracket can be stepped forward with the aid of tightening the wire rope thru the turnbuckle.
