Spacemaster® SX Electric Wire Rope Hoists

The Spacemaster® SX represents a revolutionary new generation of exceptionally reliable electric wire rope hoists, featuring advanced technology and cutting-edge performance.

An innovative design that includes a large drum diameter gives Spacemaster® SX hoists the lowest headroom and best wheel loads in the industry, while providing near true vertical lift with single reeved hoists, plus exceptional hook approaches and heights of lift. Unique features include low maintenance, sealed brakes; a two speed hoist motor; and trolley inverter control. The standard hoist nameplate will carry a CSA c/us rating as well as a NEMA 3R rating for the electrical enclosures.

Spacemaster® SX hoists are designed to meet and exceed either ASME H3 or ASME H4 duty (FEM 1Am, 2m or 3m) ratings and provide the ultimate in easy load handling, safe operation and lasting, trouble-free performance.

Standard configurations include normal headroom, low headroom and double girder trolley designs. Hoists in short ton ratings (ASME) or metric tonne ratings (FEM) meet a wide variety of application requirements:

  • 1/2 – 80 ton (500 – 80,000 kg) capacities
  • Lifts from 13ft (4m) to 320ft (100m) and beyond
  • Lift speeds 10/1.5 – 62/10 fpm (3/0.5 – 19/3 m/min)
  • 208, 230, 460, 575/3/60 or 380/3/50 power supply
  • Single-reeved or double-reeved

Crane-Tec Cranes with Spacemaster® Hoists = Savings in New Construction

  • Unmatched clearances – the floor area under your new crane can now be used more efficiently. Better hook to wall dimensions (A) compared to the competition.
  • Lower roof heights/maximum lifting heights – Your new building design can be smaller and more functional giving you savings in initial construction. Better hook to ceiling dimensions (H) compared to the competition.
  • Lower operating costs – Continual savings in heating and/or air conditioning expenses over the lifetime of your building.
  • Maximum flexibility – Factory layout and material flow planning is optimized.

Spacemaster® hoists can be fitted to most single or double girder bridge cranes.
