3.0 Pre-operational Procedures

3.1 General Information

3.1.1 When the RH Advantage trolley hoist is incorporated into lifting systems utilizing other equipment,

follow and complete all pre-operational procedures and instructions provided with the equipment. Special wiring considerations must also be taken to complete the integration of the RH Advantage trolley hoist into the system.

3.1.2 The RH Advantage trolley hoist is generally delivered pre-assembled and shrink-wrapped on a pallet

or in a wooden crate (see Figure 3-1). During shipment and storage prior to installation, the trolley hoist should be kept between –4° and +140°F (-20° and +60°C) and the relative humidity must not exceed 80%. The standard packaging is not watertight and rainproof.

3.1.3 The RH Advantage trolley hoist is shipped pre-lubricated and the gear box(s) are filled with the correct

amount and type of oil. Follow the lubrication requirements in Section 6.1 after the trolley hoist is placed into service.

3.2 Handling

3.2.1 Transportation – Move the trolley hoist utilizing a fork lift, pallet jack or hoist/crane system. Do NOT

place the trolley hoist on its side (see Figure 3-2). Do NOT stack or place anything on top of the trolley hoist or crate. Avoid swinging and unbalanced conditions (see Figure 3-3).

3.4 Assembly, Adjustments and Mounting

3.4.1 RH Advantage Trolley Hoist Installation

1) Make sure the mounting location complies with Section 3.3.

2) Install any additional devices, if any (power supply cords or pendants, for instance – see Section 3.5)

onto the trolley hoist. If the trolley hoist is not secured to a pallet, place and secure it to one making sure that the trolley hoist is completely stable (see Figure 3-6).

3) Remove the Bottom Block from the pallet/packing and place it on the ground. Use a hoist or other suitable lifting means to pickup the Bottom Block if it is heavier than 50 pounds (weight is written on the container if it exceeds 50 pounds). Always lift/hold the Bottom Block from the Hook regardless if it is lifted using a hoist or handled manually (see Figure 3-7).

4) On the counterweight side, loosen the Screws (D) that attach the Stiffening Plates (E) to Side Plates (F) and loosen the Lock-Nuts (G) on the Stirrups (H) that secure the Side Plates (F) to the Load Bars (J) (see Figure 3-10).

5) Remove the Nuts (K) and Socket Bolts (L) to remove the Spacers (M) from the Stirrups (H) so that the Side Plates (F) on the counterweight side can move freely along the Load Bars (J) (see Figure 3-11).

6) For relatively small beam flange widths (at the lower end of the flange range – see Table 2-3), the trolley Drive Shaft must be shortened to allow the Side Plates (F) to adjust close enough together as required. Drive the Spring Pin attaching the Drive Pinion, slide the counterweight side Side Plates (F) out and remove the Drive Shaft. After cutting the Drive Shaft, reinstall it onto the trolley and reattach the Drive Pinion.

3.6 Reeving and Adjustments

3.6.1 Reeving the bottom hook

1) Working from a scaffold or lifting platform, remove the Retaining Ring (B) and Load Limiter Pin (D) from the Terminal Head Crossbar (A). Let the Load Limiter (C) rotate downward and remove the Terminal Head (F) from the Lever Support/Load Limiter Assembly (C) by pulling out the Terminal Head Pin (E). (see Figure 3-17). Note and 10T trolley hoists.

2) From the ground, press the down button on the pendant until there is sufficient rope unwound to reeve the hoist. Take care not to activate the down limit switch.

3) Place the Bottom Block on the ground so that it is positioned perpendicular to the hoist, and insert the rope end into the bottom block as shown in Figure 3-18 for 4/1 reeved hoists (4 rope-falls). To make rope insertion easier, temporarily attach a wire to the end of the rope with adhesive tape and use the wire to pull the rope through the Bottom Block. Securely tie a string or cord to the end of the rope and pull the wire rope up to the hoist from the scaffolding/platform. Thread the rope through the return pulley installed in the hoist, then back through the Bottom Block (see Figure 3-

18).

4) Insert the end of the rope into the Terminal Head (F) and making sure at least 4 inches of rope extend beyond the Terminal Head (F). Install the Wedge (G) into the Terminal Head (F) and pull the rope until the Wedge (G) and the rope are tightly seated in the Terminal Head (F) (Figure 3-19).

5.0 Inspection

5.1 General

5.1.1 The inspection procedure herein is based on ANSI/ASME B30.16. The following definitions are from ANSI/ASME B30.16 and pertain to the inspection procedure below.

+ Designated Person – a person selected or assigned by the employer or employer’s representative

as being competent to perform the specific duties.

+ Qualified Person – a person who, by possession of a recognized degree in an applicable field, or

certificate of professional standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.

+ Normal Service – that distributed service, which involves operation with randomly, distributed loads

within the rated load limit, or uniform loads less than 65% of rated load for not more than 25% of the time.

+ Heavy Service – that service, which involves operation within the rated, load limit that exceeds

normal service.

+ Severe Service – that service which involves normal or heavy service with abnormal operating

conditions.

5.2 Inspection Classification

5.2.1 The Initial Inspection – a designated person shall inspect prior to initial use all new, re-installed, altered, or modified hoists/trolleys to ensure compliance with the applicable provisions of this manual.

5.2.2 Inspection Classification – the inspection procedure for hoists/trolleys in regular service is divided into two general classifications based upon the intervals at which inspection should be performed. The intervals in turn are dependent upon the nature of the critical components of the hoists/trolleys and the degree of their exposure to wear, deterioration, or malfunction. The two general classifications are herein designated as FREQUENT and PERIODIC, with respective intervals between inspections as defined below.

5.2.3 FREQUENT Inspection – visual examinations by the operator or other designated personnel with intervals per the following criteria:

Section 5.3.

+ Hoist Idle More Than 1 Year: Inspect per PERIODIC Inspection criteria in Section 5.4.

Page 31

5.6 Inspection Records

5.6.1 Dated inspection reports and records should be maintained at time intervals corresponding to those

that apply for the hoist’s PERIODIC interval per Section 5.2.4. These records should be stored where they are available to personnel involved with the inspection, maintenance, or operation of the hoist/trolley.

5.6.2 A long-range rope inspection program should be established and should include records of

examination of ropes removed from service so a relationship can be established between visual observation and actual condition of the rope.

5.7 Inspection Methods and Criteria

5.7.1 This section covers the inspection of specific items. The list of items in this section is based on those

listed in ANSI/ASME B30.16 for the Frequent and Periodic Inspection. In accordance with ANSI/ASME B30.16, these inspections are not intended to involve disassembly of the hoist. Rather, disassembly for further inspection would be required if frequent or periodic inspection results so indicate. Only a qualified person trained in the disassembly and re-assembly of the hoist or trolley should perform such disassembly and further inspection.
