Installation of Trolley Hoist on the Beam
1.
Place trolley hoist in correct position relative to bridge beam or monorail, orienting it for proper end approach in
accordance with specification requirements. Be sure that collectors and conductors are properly positioned and
aligned.
2.
Place Trolley hoist unit in position on bridge beam or monorail. Check that trolley bumpers, if provided, meet
trolley stops on beam, reposition if necessary.
The simplest ways to mount the trolley hoist on the beam, as long as the crane or building construction permits it, is to
remove the trolley stops on an open end of the beam, run the trolley onto the beam and replace the trolley stops. If this
method is not possible due to crane or building interference, mount the trolley hoist according to the following instructions
(refer to Figure 4.2.2.1).
Figure 4.2.2.1
3.
Remove side plate assembly, with the wheels intact, from one side of the trolley only, by removing the spacer pin
from the suspension shaft hole A. Then insert it into hole B. Insert cotter pin in the spacer pin to fix it in place. On
geared and motorized trolleys it is recommended that the side with the plain wheels be removed.
4.
Spread side plate G and side plate S apart. Lift the trolley up to the beam; keep both sides of the wheel and
beam at the same level.
5.
Support one side plate then push the other side towards the supported side to prevent it from shedding from the
beam. Keep the wheel and the beam at the same level.
6.
Remove the spacer pin from hole B and insert it into hole. Secure the spacer pin with the cotter pin.
7.
Check that the hoist is centered between trolley side plates and centered under the beam.
8.
The load block must hang straight and directly under the hoist. The load chain must be free of kinks, twists or
any other damage.
Trolley hoists are balanced at the factory based upon the condition of the hoist “as ordered” and “as shipped”. Auxiliary
equipment or devices furnished and mounted by others may require additional counterweights to balance the hoist. It is the
responsibility of the party mounting such auxiliary equipment or devices to add additional counterweights as necessary and
required.
If the load chain welding points are not inline you must replace the load
chain before use.
