The I-beams and spans shown in the table are for telphers.2. Span is determined by the capacity regardless of the hoist type (standard or low headroom type) or trolley type (manually-pushed, chain-driven or electrically-driven type).3. The spans shown in the table were calculated based on a deflection of approx. 1/1500.Grounding of the hoistSecurely ground (earth) the hoist in the same way as that for ordinary electrical products.Catenary hoists:In the case of direct installation on a steel frame structure, ground the hoist completelyto the shape steel after removing the paint and rust from the contact part to a sufficientdegree. In the case of installation on a wooden structure, completely ground the mainbody of the hoist using a copper wire with a diameter of 2.6mm or larger.Stoppers for traversing railsHoists with trolleyGround the I-beam basically in accordance with the instructions given in the left.Do not paint the traversing surface. As the traversing wheels of the hoist arecoated with anti-rust paint, remove the paint from the part that will come incontact with the I beams before installation.Stoppers for standard headroom type hoists and low headroom type hoistsAbout installation of stoppers for Double-RailType hoistsStoppers must be installed in such a way that thewheels of the hoist come in contact with the bothsides of the traversing rail simultaneously.The stopper height ( “a” ) must be at least onefourth of the wheel rolling diameter.Double-Rail Type hoists employ an automaticcenter adjustment structure in which the axle onthe Driven side is deviated so that the 4 wheelscontact the surface completely. For this reason,the amount of deviation varies depending on theheight difference between the right and left rails.Stoppers must be installed in such a way that theright and left wheels come in contact with themsimultaneously taking into consideration theamount of the deviation due to the rail heightdifference.The diameter of the wheel rolling contact sectionof the stopper must be “the wheel rolling diameter+ 10mm.”Capacity(t)2-57.5-10Stoppers for Double-Rail Type HoistsWheel rolling diameter(d)160195Drive sideAxle is not deviated.Diameter of the wheel rolling contact section(D)170205StopperDriven sideDifference in the stopper installationlocation due to the axle deviation.This difference varies depending onthe height difference between the rightand left rails.

Values shown inthe table below must be used. In the case of specialspecifications, calculate the C value from the W andP values.Capacity (t)W(drive side /driven side)PC0.5-2230310200290(230410)250330 32732796452.8, 3, 7.512840(90)5, 10156140(drive side /driven side)For high hoisting lift trollies (low headroom type) only.3215, 202000Stoppers must be installed in such a way that thewheels on both sides come in contact with themsimultaneously.
