ED1050 KITS

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

1.1Remove the load chain stopper.

1.2Remove the load chain and bottom hook.

1.3Remove chain container (if required).

1.4Remove top hook assembly.

1.5Remove the hoist nameplate.

1.6Remove the motor nameplate.

2.ED1050 Hoist Assembly

2.1Install the Connection Yoke Complete Set (Figure 5).

2.2Temporarily 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.

2.3Install 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).

EDCK1, EDCK2 specifications

Harrington Hoists has long been recognized for its high-quality hoisting solutions and has made significant strides with its EDCK series. The EDCK2 and EDCK1 models are notable electric chain hoists that cater to varying lifting requirements in industrial settings.

One of the main features of the Harrington EDCK series is its compact design. The EDCK1 and EDCK2 models are engineered to fit into tight spaces while still delivering powerful performance. Despite their small footprints, these hoists offer impressive lifting capacities, making them suitable for a range of applications, from light-duty tasks to heavier industrial operations. The EDCK1 has a lifting capacity of up to 1 ton, while the EDCK2 reaches up to 2 tons, catering to diverse needs.

Another highlight of the EDCK series is their user-friendly operation. The ergonomic control pendant ensures that operators can maneuver loads safely and efficiently. Additionally, the hoists come equipped with a durable, high-speed motor that provides swift lifting and lowering capabilities. This is particularly beneficial in busy work environments where time is of the essence.

Technologically, the EDCK series incorporates high-quality components that enhance performance and reliability. The hoists are fitted with a heavy-duty chain that undergoes rigorous testing to ensure longevity and reduced wear. Harrington Hoists also incorporates advanced overload protection systems, which prevent the hoist from exceeding its rated capacity, thus safeguarding both the equipment and the operator.

Safety features extend beyond overload protection, as the EDCK models also feature a reliable limit switch that prevents the hook from exceeding its maximum travel distance. This technology significantly reduces the risk of accidents, ensuring that operations can be conducted with peace of mind.

A standout characteristic of the EDCK series is their quiet operation. The design minimizes noise during lifting operations, which is particularly advantageous in settings where sound levels need to be controlled. This focus on user comfort and workplace tranquility is often a deciding factor for users in industries that require consistent operation without disruptive noise.

In summary, the Harrington Hoists EDCK1 and EDCK2 models present an exceptional blend of performance, safety, and user-friendly features. With their impressive lifting capacities, compact design, robust safety technologies, and quiet operation, they stand out as ideal solutions for anyone searching for reliable electric chain hoists in a variety of industrial applications.
