Electric Hoists

The entire range of PBL ElectricHoist has been designed inaccordance with the latest rulesfor the manufacture of materialhandling equipment and to meetthe continuously increasingdemands of hoist efficiency.

The construction of these hoistsis based on InternationalStandards and also on theRules for the Design of SerialLifting Equipment issued by theFederation of European HoistManufacturers FEM.

PBLs long experience inmanufacturing power transmission drives and similar products under foreigncollaboration and technicalknow how , is your guaranteefor a high standard of quality

and reliability of design.

Modern manufacturing facilitiesand techniques allow efficientseries manufacture andinterchangeability of parts.

1. Hoist Motor is a fan cooled ,brake motor, as per IS 325 suitable for 40% dutycycle, S4 duty and 150starts / hour. Typr of motor enclosure is IP 55.Motor is

protected by fuse andoverload relays in controlcircuit from failure causedby excessive starts,

heavy-duty cycle or abnormal voltage drop, etc.The motors are with class Finsulation.

2. Limit Switches wired in thecontrol circuit are adjustableand limits highest andlowest position of hook.

3. Flange Plates are gradedcast iron castings with veryhigh wear-resistanceproperty and are accuratelymachined, fitted with cagedroller bearing.

4. Hoist Barrel with smoothmachine cut grooves ismade from seamless tubewith high tensile strength.The pressed -in internalgear ring is heat treated toapprox. 90-100 kg/mm2

tensile strength.

5. Rope guide of very highwear resistant property,manufactured fromPolyurathane, preventsslack rope and retains wirerope in the barrel grooves.For special applications acast iron rope guide isprovided.

7. Gear Bo x with helical gearsand pinions mounted on ballbearings ensure quiterunning. Gears are madefrom high quality alloy steeland suitably heat-treated togive long, trouble-free

service.8 . Rope Sheaves of bottom

blocks and equalisingpulleys are mounted on ballbearings. The load hooks,manufactured inaccordance with ISstandards, swivel on thrustbearings.

9 . Control of all motors is byelectro-magnetic contactors..

6. Steel Wire Rope is flexibleand of multistrandconstruction withguaranteed breakingstrength, which gives long

service. Galvanized wirerope is provided as per IS2266

Power Build is manufacturing hoist as per technical know-how from M/s KULI-Germany.

Manufacturing range of Power Build make hoist.

1. Foot mounted hoist2. Mono rail trolley drive hoist3. Hoist with double girder crab4. Flexible trolley drive hoist to travel on curved beam5. Twin Hoist

1) Foot mounted hoist

Foot mounted hoist can be used as a winch. It has one rope pay-off.

2) Hoist with double girder crab

This type of hoist is traveling on two parallel girders.

Hoist travels on rails through amotorized trolley.

These types of hoist are available in2 or 4 rope falls.

There is one rope pay-off from ropedrum and it is converted into 2 or 4rope falls by an equalizing arm and rope anchor beam.


4/9

3) Monorail trolley drive

Monorail trolley drive hoist travels on I-beam. Travel of hoist on beam is by motorized trolley. In this type of hoist on one side of beam there

is a counter weight box. The weight is to be filled in counter weight

box to balance the weight of hoist. These types of hoist are available in 2 or 4 rope

falls. There is one rope pay-off from rope drumand it is converted into 2 or 4 rope falls by anequalizing arm and rope anchor beam.

4) Flexible trolley drive hoist

Flexible trolley drive hoists are mainly used on I-beam, which has curved path.

Hoist is mounted on I-beam. Hoist travelson beam through a motorized trolley.

These types of hoists are available in 2 or 4rope falls. There is one rope pay-off fromrope drum and it is converted into 2 or 4rope falls by an equalizing arm and ropeanchor beam.


5/9

5) Twin Hoist

Twin Hoists Are Combined Unit of TwoHoists Operating At a Time

Out Of Two Hoists, One Hoist Has RightHand Grooves and Other Hoist Has LeftHand Grooves.

For foot-mounted hoist working as a winch, only hoist with control panel and pendent push buttons are provided.

For monorail trolley drive, double girder crab and flexible trolley drive hoists, hoists aresupplied with hook, control panel and pendent push button to operate hoist from operatingfloor.

How to select your Electric Hoist

Information required for selection of the most economical and suitable hoists:

1. Load capacity in Tones2. Duty Class: Light, Medium, Heavy3. Height of lift: Total/ Average4. Load cycles per hour 5. Working hours per day6. Lifting speed in meter per minute

In order to facilitate the selection of hoist bearing in mind the need for a long service life, it is necessaryto classify the Hoists in to groups as in Table 1(Below).

These classification consider the average running time (hours/day) and the duty class, both clearlydefined in the "Rules for the Design of Serial Lifting Equipment" of FEM and in the new Germanstandards DIN 15020 being the basic for the design of our hoists.

Average running time - hrs/day: This only considers the effective lifting and lowering time. The averagerunning time is estimated or calculated as follows:

Average running time - hrs/day:

2 * average height of lift/m * load cycles/hr * working hrs/day== ---------------------------------------------------------------------------------

60 * lifting speed (m/min)

Duty Class: Generally, the duty classification is estimated.

Class DutyLight - Occasional loads of rated capacity. Majority of loads less than 50% of rated capacity.Medium - Majority of loads in the vicinity of 50% of rated capacity average duty class

Heavy - Majority of loads greater than 50% of rated capacity.

Having determined the group classification from table 1, the hoist can be selected from Table 2 takinginto consideration the lifting speed and the height of lift.

Please consult us for special service condition or for classification of hoists as * marked.
