EDCK1 & EDCK2  
INSTALLATION INSTRUCTIONS  
1050LB CAPACITY  
PURPOSE  
To provide instructions for installing the ED1050 Kit. The ED1050 kit provides a method to increase the capacity  
of the ED525 hoist to 1050 pounds by converting the hoist from single fall to double fall.  
SCOPE  
WARNING  
The ED1050 kit can only be installed on the ED525S and DS model hoists. It cannot be  
installed on an ED525 with an ET525 Mini Trolley. For trolley-mounted applications the hoist must be mounted on  
an appropriate capacity push or geared trolley. Reference the Manual Trolley, TF2/TS2 Series, Owner’s Manual  
for installation instructions.  
CAUTION  
Hoist lift and lifting/lowering speed are affected by installing the ED1050 kit. The lift is halved  
(approximately) by installing the double fall kit, therefore load chain length must be increased accordingly.  
Further, the chain container size must be increased to accommodate the longer load chain. Do not exceed the  
maximum capacity of the chain container. Lift/lowering speeds are reduced by half to 22 ft/min for the single  
speed hoist and 22/6 ft/min for the dual speed hoist.  
ED1050 KIT INSTALLATION  
Before installing ED1050 kit, reference the parts list (page 9) to confirm that all the parts are in the kit.  
DANGER  
Before proceeding, ensure that the electrical supply for the hoist has been de-  
energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel Protection -  
Lockout/Tagout of Energy Sources”.  
1. ED525 Hoist Disassembly  
1.1 Remove the load chain stopper.  
1.2 Remove the load chain and bottom hook.  
1.3 Remove chain container (if required).  
1.4 Remove top hook assembly.  
1.5 Remove the hoist nameplate.  
1.6 Remove the motor nameplate.  
2. ED1050 Hoist Assembly  
2.1 Install the Connection Yoke Complete Set (Figure 5).  
2.2 Temporarily connect power to the hoist. Invert hoist so chain guide is at the top of the hoist. Insert chain  
into chain guide on the load side (side away from chain container mounting point). Be sure to keep  
welds of the vertical links oriented away from load sheave. Press the UP button and make sure chain  
feeds though the chain guide smoothly. If the chain jams and the friction clutch slips, STOP  
OPERATION. Press DOWN button and remove chain from unit. Re-insert chain until chain moves  
though the chain guide smoothly.  
2.3 Install the Bottom Hook Complete Set (Figure 23). Include the chain spring (Figure 37), washer (Figure  
38) and cushion rubber (from ED525) on the load side of the load chain. Making sure there is no twist in  
the load chain attach the chain to the joint yoke (Fig. 15) with chain pin (Fig. 20).
