The document is an Operator's Manual for the Sumner Series 2100 Contractor Lifts, published in May 2024. It provides comprehensive information on the safe operation, maintenance, and specifications of these lifts.

Function Description:

The Sumner Series 2100 Contractor Lifts are designed for lifting and lowering loads in various work environments. They are manually operated lifts, featuring a winch assembly for controlled raising and lowering of the fork carriage. The lifts are portable, equipped with 10" transport wheels and 5" casters for mobility, and can be configured with stabilizer legs for enhanced stability when handling heavier or bulkier loads. The forks can be reversed to accommodate different load configurations, and optional accessories like fork extensions and a boom are available to expand their utility. The manual explicitly states that these are not personnel lifts and should never be used for hoisting or moving people.

Important Technical Specifications:

The Series 2100 Contractor Lifts come in three models: 2112, 2118, and 2124, with varying maximum lift heights.

Dimensions (for all models unless specified):

Height - stowed: 84" (213.4 cm)
Length - stowed: 34" (86.4 cm)
Height - operating: 84" (213.4 cm)
Length - operating:
- 2112: 62" (157.5 cm)
- 2118 & 2124: 73" (185.4 cm)
Base width: 31.25" (79.4 cm)
Width with stabilizer legs: 74" (188.0 cm)
Ground clearance: 2.5" (6.4 cm)
Load height (minimum): 6" (15.2 cm)
Maximum height (forks down):
- 2112: 10' 11-5/8" (3.3 m)
- 2118: 16' 4-5/8" (5.0 m)
- 2124: 21' 9-5/8" (6.6 m)
Maximum height (forks reversed):
- 2112: 12' 11-3/8" (3.9 m)
- 2118: 18' 4-3/8" (5.6 m)
- 2124: 23' 9-3/8" (7.2 m)

Weight:

Net weight:
- 2112: 255 lbs. (115.9 kg)
- 2118: 327 lbs. (148.6 kg)
- 2124: 372 lbs. (169.1 kg)

Load Capacity:

Load capacity, 14" load center: 650 lbs. (300 kg) for all models.
Load capacity with fork extensions: 200 lbs. (90 kg) for all models.
Boom Capacity Chart:
- Station 1: 650 lbs. (300 kg)
- Station 2: 525 lbs. (240 kg)
- Station 3: 425 lbs. (195 kg)
- Station 4: 300 lbs. (140 kg)
- Station 5: 200 lbs. (90 kg)
- The load capacity decreases as the distance from the back of the fork increases. The load capacity chart illustrates this relationship, showing a maximum safe load of 650 lbs at 9 inches from the back of the fork, decreasing to 100 lbs at 44 inches.

Fork Specifications (for all models):

Standard fork width: 21.5" (54.6 cm)
Standard fork length: 28" (71.1 cm)
Fork length with extensions: 42" (106.7 cm)
Fork weight: 32 lbs. (14.5 kg)
Fork weight with extensions: 38 lbs. (17.3 kg)

Usage Features:

Pre-Operation Inspection: Before each use, operators must check all moving parts, wire rope (cable), and ensure smooth operation. Any visible damage or issues with smooth movement warrant not using the unit. The wire rope must have a minimum of four complete wraps around the winch drum.
Proper Operating Position: Operators should maintain balance and proper footing, operating the lift from the designated operator position.
Work Area Safety: The work area must be clear of obstructions, and bystanders, especially children, should be kept at a safe distance. Horseplay around the equipment is prohibited.
Load Handling: Loads must be properly balanced and secured to the forks before lifting. The center of gravity of the load should always be centered between the fork arms and as far back towards the lift as possible, never extending past 22" on standard forks or 36" on extended forks.
Moving the Lift:
- No Load: The lift is moved on its 10" tires or four caster wheels. It should not be pulled by the load lifting cable. To tilt the unit for transport, the carriage must be lowered, the Mast Hold Down Bar engaged, and the unit tilted by grasping the legs past the casters.
- With Load: Light loads can be transported on the four caster wheels on a level surface, with the load in the lowest possible position and secured to the fork to avoid shifting. Movement with elevated loads should be limited to short distances (10-15 feet/4-5 meters), slowly, and with personnel clear of the load and behind the operator.
Stabilizer Legs: Recommended for loads weighing 400 pounds or more, or when extended to heights greater than 12 feet, or for any large, bulky loads. They are deployed by pulling them down until the caster on each leg is snug on the floor.
Reversing Forks: The fork assembly can be rotated 180 degrees by disengaging and re-engaging four spring-loaded pins. When reversed, the load must be secured and not extend beyond the fork stop.
Mast Hold Down Bar: Used to secure the carriage in the lowered position, especially during transport or storage.
Mast Brakes: Automatically engage when the unit is horizontal, preventing mast section disassembly. A special tool (or a homemade alternative) is required to release them.
Options:
- Fork Extensions: Slide out from the fork arms and lock into position with plungers.
- Boom: Attaches to the mast, allowing for lifting at various stations with corresponding load capacities. The plunger must be engaged in the locating hole for safe operation.

Maintenance Features:

Regular Inspections:
- Before Each Use: Check cable for kinks/frays (replace if more than 3 wire strands are broken), winch operation, forks/legs/base for bends, and caster wheel movement. Verify stabilizer leg locking mechanism.
- Every 6 Months: Detailed inspection of cable, winch parts, and brake system.
Cable Replacement: A detailed procedure is provided, including cutting the old cable, fusion welding the new cable end (must be straight and smooth), threading it through the unit, and bolting it to the top mast. The cable must be fed from the bottom of the winch, between the winch and mast sections.
Winch Maintenance: Ensure winch covers are on, check ratchet dog and brake ratchet for wear (lubricate if needed), inspect gear teeth for wear (lubricate with 50-wt. motor oil), and adjust the brake as per troubleshooting.
General Maintenance: Check winch handles for wear/bends, inspect roller wheels for damage/smooth rotation, ensure all bolts/nuts are tight, check legs/forks/braces/base for damage, verify pulley covers are undamaged and pulleys rotate freely, and inspect mast sections for smooth sliding action (lubricate with silicone).
Troubleshooting Guide: A comprehensive section addresses common issues like masts not rising, slow load easing, winch problems, and safety brake issues, providing causes and solutions. For example, if masts are not rising in succession, potential causes include overloading, improperly centered load, or mast roller issues. Solutions range from removing excess weight to cleaning and lubricating components or replacing damaged parts.
Safety Brake Adjustment: Specific instructions are provided for adjusting the 2100 Lift winch, ensuring the pinion and drive shaft are correctly positioned when the lock nut is tightened to 15 ft. lbs.
Replacement Parts: Emphasizes using only factory replacement parts to maintain quality and safety.
Maintenance Record: A dedicated page is included for recording maintenance actions and dates, allowing for tracking of service history.
