Hyster E30 50B, E60BS, E60 120B service manual
- From dock to stock and anywhere in between, the Hyster® E30-40HSD3 series is your versatile materials handling workhorse. Engineered with superior ergonomics, these 3,000 to 4,000-pound capacity three-wheel stand-up lift trucks are easy to operate and easily demonstrate that increased operator comfort helps to improve productivity. MORE ACTION, LESS RE-ACTION Work can be hard. And gritty. But maneuvering and maintaining your materials handling equipment shouldn’t be.
- You need a lift truck that consistently and efficiently maneuvers in and around tight spaces and, at the end of the shift, one that is easily cleaned and maintained. Shouldn’t your lift truck be as tough as the warehouse it works in? The Hyster® E30-40HSD3 three-wheel stand lift truck has a small turning radius — turning in smaller aisles and dock operations than a sit-down unit. Your operators can save valuable time and be more productive when using one forklift that can handle the big and small spaces. When a job gets dirty, so does your forklift. But that’s no challenge for this forklift. With sealed electrical connectors as well as enclosed master drive units and motors, you know that harmful dirt and grime will stay out of the components and washing down this forklift will be worry-free. The AC traction and hoist motors eliminate the need for commutating brushes, and can reduce maintenance requirements.
- Cooler/freezer options are available for extreme environments. A tough forklift comes with a great warranty: 12 month/unlimited hours full forklift limited warranty 36 month/6,000 hour powertrain limited warranty Lifetime frame warranty (Offered to the original owner only. Contact your Hyster® dealer for full details.) STAND UP FOR THE RIGHT TO BE COMFORTABLE Your operators can spend a lot of time getting in and out of a sit-down lift truck to pick and move product. Wouldn’t it make sense to eliminate some of that effort and make it easier for them to do their jobs? Are your operators sitting on the job when they should be standing? The E30-40HSD3 three-wheel stand forklift is an operator’s dream
- . Easy on/off access, low step height and a spacious suspended floor help to alleviate fatigue and can increase productivity. Your operators will be in control with fully proportional travel, lift/lower, tilt, and sideshift functions. With more usable floor area than leading competitors, and no pedals to stand on to enable travel, your operators can adjust posture freely.
